| − | <h2>A layman's guide - <span style="font-size:150%;color:#0000ff;">How to compile ReactOS.</span></h2>
| |
| − |
| |
| − | In this tutorial there is also a Unix based subsection (this requires updating to git).
| |
| − |
| |
| − | Git has now replaced SVN, so this tutorial now describes how to download the source with Git.
| |
| − |
| |
| − | You will need to install '''git''' for Windows from '''https://git-for-windows.github.io/''' and '''TortoiseGit''' from '''https://tortoisegit.org/'''.
| |
| − |
| |
| − | Next you will need to create a master folder to keep all the next folders in one place. This folder can be created in C: or D: (or any other drive partition), for example '''D:\ReactOSDevelopment''' or '''C:\ROS'''.
| |
| − |
| |
| − | Create the following folders in your master folder:
| |
| − |
| |
| − | 1. '''\source''' (the name does not matter - you will download the source tree into this folder).
| |
| − |
| |
| − | 2. '''\compiled''' (the name does not matter - this is the output folder where the binaries are complied to and the ISO is created).
| |
| − |
| |
| − | 3. '''\RosBE''' (this is where you will install RosBE).
| |
| − |
| |
| − | You should now have something like the following examples.
| |
| − |
| |
| − | Example No1
| |
| − |
| |
| − | '''C:\ROS\source'''
| |
| − |
| |
| − | '''C:\ROS\compiled'''
| |
| − |
| |
| − | '''C:\ROS\RosBE'''
| |
| − |
| |
| − | or
| |
| − |
| |
| − | Example No2
| |
| − |
| |
| − | '''D:\ReactOSDevelopment\source'''
| |
| − |
| |
| − | '''D:\ReactOSDevelopment\compiled'''
| |
| − |
| |
| − | '''D:\ReactOSDevelopment\RosBE'''
| |
| − |
| |
| − | Using example No2, within '''D:\ReactOSDevelopment\''' create a '''compiled''' folder, a '''RosBE''' folder and a '''source''' folder.
| |
| − | Next, navigate into '''D:\ReactOSDevelopment\source''' and right click within the folder, then select '''Git Clone''', then in the next window, enter this url '''<nowiki>https://github.com/reactos/reactos.git</nowiki>'''; this will create a '''reactos''' folder and download the current source tree into it.
| |
| − |
| |
| − | I have noticed this behaviour with Git; if you first copy the url, then click in the source folder, you will find that Git has put the copied url in the '''Url''' input and put the path to your source folder with the addition of reactos, in the '''Directory''' input.
| |
| − | See <sup>[<span style="color:#0000ff">'''1'''</span>]</sup> <sup>[<span style="color:#0000ff">'''2'''</span>]</sup> <sup>[<span style="color:#0000ff">'''3a'''</span>]</sup> <sup>[<span style="color:#0000ff">'''3b'''</span>]</sup> <sup>[<span style="color:#0000ff">'''4'''</span>]</sup> in the '''Getting the source with Git''' section below.
| |
| − |
| |
| − | For how to update your local source, see the subsection '''Updating a local source tree with Git'''.
| |
| − |
| |
| − | Having downloaded the source you will now need to download and install the ReactOS Build Environment <sup>[<span style="color:#0000ff">'''5'''</span>]</sup> <sup>[<span style="color:#0000ff">'''6'''</span>]</sup> <sup>[<span style="color:#0000ff">'''7'''</span>]</sup>
| |
| − | (a link to the latest version <small>(''Windows and Unix'')</small> can be found here: '''https://www.reactos.org/wiki/ReactOS_Build_Environment''') into '''D:\ReactOSDevelopment\RosBE''' (I select to have a desktop shortcut. See also <span style="color:#dd0000">'''Note'''</span>), then start it, and from it's command prompt: <sup>[<span style="color:#0000ff">'''8'''</span>]</sup>
| |
| − |
| |
| − | '''1'''. Navigate to '''D:\ReactOSDevelopment\compiled''' and type '''D:\ReactOSDevelopment\source\reactos\configure ninja'''
| |
| − |
| |
| − | '''2'''. Still within '''D:\ReactOSDevelopment\compiled''' type '''ninja bootcd'''
| |
| − |
| |
| − | or
| |
| − |
| |
| − | '''3'''. Still within '''D:\ReactOSDevelopment\compiled''' type '''ninja livecd'''
| |
| − |
| |
| − | or
| |
| − |
| |
| − | '''4'''. Still within '''D:\ReactOSDevelopment\compiled''' type '''ninja hybridcd'''
| |
| − |
| |
| − | or if want all three ISO images
| |
| − |
| |
| − | '''5'''. Still within '''D:\ReactOSDevelopment\compiled''' type '''ninja bootcd livecd hybridcd'''
| |
| − |
| |
| − |
| |
| − | Now you should find the '''bootcd''' and/or the '''livecd''' and/or '''hybridcd''' in '''D:\ReactOSDevelopment\compiled\reactos'''.
| |
| − |
| |
| − | If you have problems compiling after you have updated your local source tree, try typing '''ninja clean''' and then start again at step '''1''' above.

| |
| − | ===<span style="color:#0000ff">How to compile ReactOS - '''Unix subsection'''</span>===
| |
| − | You will need '''Git''', which should be in your system. To test for Git, type '''git --help''' at the command prompt in a terminal window, if it doesn't displayed the help text, then you will have to install it through your package manager.
| |
| − |
| |
| − | You will also need to download the ReactOS Build Environment (RosBE), from '''https://www.reactos.org/wiki/ReactOS_Build_Environment'''
| |
| − |
| |
| − | '''Example:'''
| |
| − |
| |
| − | Unpack the RosBE installation files to '''/home/RosBE-Unix-2.1.2''' directory.
| |
| − |
| |
| − | Create the following folders '''/home/RosBuild''' then '''/home/RosBuild/RosBE''' (install RosBE in this folder).
| |
| − |
| |
| − | '''Note:''' The default directory for RosBE, is '''/usr/local/RosBE''', if you prefer, you can use that.
| |
| − |
| |
| − | To continue with my example; Open the folder '''/home/RosBE-Unix-2.1.2''' and right click within <sup>[<span style="color:#0000ff">'''9'''</span>]</sup>, for the menu, '''Window''' - '''Terminal Here''' <sup>[<span style="color:#0000ff">'''10'''</span>]</sup>.
| |
| − |
| |
| − | In the terminal window, run the builder script by typing '''./RosBE-Builder.sh'''
| |
| − |
| |
| − | If it reports any missing tools <sup>[<span style="color:#0000ff">'''11'''</span>]</sup>, you will need to install them (the package '''devx.sfs''' worked for me).
| |
| − |
| |
| − | Then run the script as before, and if it reports all tools '''OK''' <sup>[<span style="color:#0000ff">'''12'''</span>]</sup>, then you can continue.
| |
| − |
| |
| − | To follow my example, type '''/home/RosBuild/RosBE''' for the install directory and then follow the instructions from the running script.
| |
| − |
| |
| − | If all went well, then it will ask you about creating a shortcut, just follow the instructions.
| |
| − |
| |
| − | I created the shortcut in '''/home''' then copied it onto the desktop and checked to see if it ran RosBE.
| |
| − |
| |
| − | To populate your source folder, you will need to open a terminal window within the empty source folder; right click - '''Window''' - '''Terminal Here''', then at the command prompt, type: '''git clone https://github.com/reactos/reactos.git'''. This will create a folder called '''reactos''' and download the main source code.
| |
| − |
| |
| − | To get the revision number, right click on the reactos folder and select '''Window''' - '''Terminal Here''', then at the command prompt, type: '''git describe''', which will display something like this '''0.4.7-dev-532-g3cd76b91b5'''.
| |
| − |
| |
| − | The alternative to the 'Right click-Window-Terminal Here' method, is to type the full address, eg. '''/home/RosBuild/source'''.
| |
| − |
| |
| − | To update the source code, right click within the reactos folder and select '''Window''' - '''Terminal Here''', then at the command prompt type: '''git pull https://github.com/reactos/reactos.git'''
| |
| − |
| |
| − | '''NOTE''': You must be '''actually in''' the '''source''' folder to clone and '''actually in''' the '''reactos''' folder to update the source or get the revision number.
| |
| − |
| |
| − | ====Compiling====
| |
| − |
| |
| − | Start RosBE and at the terminal command prompt type '''cd /home/RosBuild/compiled''' (or the directory that you want ReactOS to be built into).
| |
| − | Then type '''/home/RosBuild/source/reactos/configure.sh'''. When the script finishes, type '''cd /home/RosBuild/compiled/reactos/''' and then '''ninja livecd''' or '''ninja bootcd'''

| |
| − |
| |
| − | This guide shows you how to, using the built in ReactOS debugger, get a debug log. You will need to install or run one of the debug ISOs in the list below and choose '''Debug''' mode at the boot options menu <sup>[<span style="color:#b60000">'''1'''</span>]</sup>; for other modes see '''Variations''' below, but please read this section first.

| |
| − | * A test computer with a serial port.
| |
| − | * A second computer with a serial port and Putty installed (or similar app).
| |
| − | * A nullmodem cable to connect both computers.
| |
| − | ===Software===
| |
| − | Win32 Putty - http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html You will also find the source code for Windows and Unix at this link, but Linux users may be able to get Putty through their Package Manager.
| |
| − |
| |
| − | === Setting up Putty. ===
| |
| − | There are some vital settings in Putty, which need to be set, so that Putty can capture a debug log.
| |
| − | In putty go to '''Category''' and select '''Session''', then set the following inputs to these values:
| |
| − | <br />
| |
| − | '''Serial line''' = '''COM1'''
| |
| − | <br />
| |
| − | '''Speed''' = '''115200'''
| |
| − | <br />
| |
| − | '''Connection type''' = '''Serial'''
| |
| − |
| |
| − | Back to '''Category''' and select '''Logging''', in '''Session logging:''' check '''All session output'''. Note where Putty saves the log file and change if required; use the '''Browse''' button for the destination folder.

| |
| − | === The ReactOS debugger ===
| |
| − | The ReactOS debugger has some commands that can be used from the command line; all of the commands are typed into the ReactOS test computer, but will be viewed in the terminal window (i.e putty) on the second computer. To enter a command, press the hotkey combination of '''Tab'''<small>+</small>'''k''', which halts the system and gives you the command prompt which looks like this: '''kdb:>''' where you can then enter the command.
| |
| − |
| |
| − | ==== Commands: ====
| |
| − | '''Tab'''<small>+</small>'''k''' - this command halts the system so you can enter commands into the debugger.
| |
| − | <br />
| |
| − | '''bt''' - this command gives a backtrace; use it when ROS enters the debugger (see below).
| |
| − | <br />
| |
| − | '''cont''' - this is short for continue.
| |
| − | <br />
| |
| − | '''set condition <big><big>*</big></big> first always''' - this command tells ROS to enter the debugger on the first exception.
| |
| − |
| |
| − | The following is an example of when ROS enters the debugger (see also in the <sup>[<span style="color:#b60000">'''4'''</span>]</sup> screenshot below):
| |
| − | <br />
| |
| − | <span style="color:#ffffff;background:#000000">Entered debugger on last-chance exception (Exception Code: 0xc0000001) (Unknown/User defined exception)<br />kdb></span>
| |
| − |
| |
| − | === Getting a backtrace: ===
| |
| − | By looking in the Putty window, you will see when ROS enters the debugger, when that happens, you need to enter '''bt''' at the command prompt, like so:
| |
| − | '''kdb:> bt''' <sup>[<span style="color:#b60000">'''4'''</span>]</sup> and press '''enter''' on the keyboard.
| |
| − | You may see this
| |
| − | <br />
| |
| − | '''--- Press q to abort, any other key to continue ---''' <sup>[<span style="color:#b60000">'''5'''</span>]</sup>
| |
| − | <br />
| |
| − | If you do see it, then just press any key other than q, it may show again, just repeat until you are back at the command prompt of '''kdb:>'''
| |
| − |
| |
| − | === Getting a more detailed backtrace: ===
| |
| − | When you see debug info streaming into putty <sup>[<span style="color:red">Note</span>]</sup>, then press the hotkey combination of '''Tab'''<small>+</small>'''k''' on your keyboard, then type '''set condition <big><big>*</big></big> first always''' at the command prompt and press '''enter''' on the keyboard, then type '''cont''' <sup>[<span style="color:#b60000">'''6'''</span>]</sup> and press '''enter''' on the keyboard. Setting the condition to first always, will make ReactOS enter the debugger on every exception, which it will do many times, and each time you will have to type '''bt''' then '''cont'''.
| |
| − |
| |
| − | <div style="border:1px solid #dd0000;padding:5px"><span style="color:#ff0000">'''Note'''</span>: If you are testing an app, then it is better to wait until you are ready to run the app, before setting the condition to first always, else you could be overwhelmed with ReactOS entering the debugger.</div>
| |
| − |
| |
| − | === No working keyboard! ===
| |
| − | Currently <small>(Jan 2015)</small> usb support is problematic, so your keyboard may not work! If you have found that your usb keyboard does not work with ReactOS, and ReactOS bsods at or before the first input window in the installation process, but after it is running in memory, you should still be able to get a debug log by using a '''livecd debug''' version (example: '''reactos-livecd-0.4.7-dev-575-g48b2714-x86-gcc-lin-rel.7z'''). The livecd versions currently default to '''Debug''' mode, so when it boots, it will output debug info to the serial port, but you will not be able to get a '''backtrace'''!
| |
| − |
| |
| − | === Advice: ===
| |
| − | '''Do not''' use '''Tab'''<small>+</small>'''k''' and '''bt''' to get a '''backtrace''', when ReactOS does not automatically enter the debugger! If you think by doing so, you will get some more useful information for the dev's to work with (which I have done in the past), you will not, it is a waste of time, the backtrace is of no value!
| |
| − |
| |
| − | Putty names the file putty.log, it would be a good idea to re-name it, because the next time that putty is run, it will over-write the file called "putty.log". I use something descriptive, in this format "'''''app name - ReactOS revision number'''''", for example "'''gimp-1.0.4 [0.4.7-dev-575-g48b2714]'''".
| |
| − |
| |
| − | '''TIP:'''
| |
| − | If you find that when you use the test computer's keyboard to enter commands, nothing appears at the Command Prompt on the second (receiving) computer, then type the command on the second computer's keyboard, you then should see what you type appear at the Command Prompt.
| |
| − |
| |
| − | === Variations ===
| |
| − | '''RosDbg''' - This is only useful when ReactOS is compiled with a Microsoft compiler, which adds extra debugging code into ReactOS, which can output extra debug info. In use, the difference is in the keyboard input, where you can only use '''Tab''' <small>+</small> '''k''' on the ReactOS test computer, all other keyboard input is via the logging computer's keyboard.
| |
| − |
| |
| − | '''Screen''' - In this mode, debug information is written to the screen and you will have to take photos to be able to submit the information in a JIRA Issue. Any keyboard input is done on the ReactOS test computer keyboard. The instructions for '''Debug''' mode also apply to '''Screen''' mode.
| |
| − |
| |
| − | '''Log file''' - This writes all debug output to a '''debug.log''' at '''C:\reactos\''', on the ReactOS test computer's hard drive. Any keyboard input is done on the ReactOS test computer keyboard. You may, also need to use a Linux livecd to be able to recover the log file from the test computer.

| − | === Getting a debug log from VirtualBox ===
| |
| − | This section covers a simple VirtualBox setup using com0com or tty0tty as a virtual null modem cable to connect to Putty; all running on the same computer, no need for a real null modem cable and a second computer.
| |
| − |
| |
| − | VirtualBox for Windows, Unix, can be down loaded from https://www.virtualbox.org/ (plus installation help, should you need it), it is also available for Unix through your package manager.
| |
| − |
| |
| − | '''Note''' that for Unix, you will need to have the development package and the kernel source or header files installed.
| |
| − |
| |
| − | Install VirtualBox for your operating system, then start it. You will first need to create a virtual machine to install ReactOS into; this is done by clicking on the blue '''New''' button. In the first setup window you will need to give it a name in '''Name:''', then set it to '''Microsoft Windows''' in '''Type:''' and then set it to, either '''WindowsXP(32bit)''' or '''Windows 2003(32 bit)''' in '''Version:''', then for a simple setup, you can accept all the defaults in all the other setup windows (I alter just one item, I select '''VHD (Virtual Hard Disk)''' in the last setup window). There is no need to install ReactOS into the virtual machine just yet, if you want to log the debug output from the start of an installation.
| |
| − |
| |
| − | '''Note:''' You may find it helpful if you name the virtual machine with a descriptive name, such as '''0.4.7-dev-582-g74cc915''' or '''ReactOS-g74cc915''' or '''ROS-0.4.6''' (g74cc915 is a revision number and 0.4.6 is a release number), especially if you intend doing some serious debugging and having several virtual machines with different versions of ReactOS installed.
| |
| − |
| |
| − | There is another user's wiki here https://www.reactos.org/wiki/User:Matthiasbasler which covers a more detailed setup for VirtualBox.
| |
| − |
| |
| − | ====Windows - com0com====
| |
| − |
| |
| − | Get the latest '''com0com''' from https://sourceforge.net/projects/com0com/files/com0com/ and install it. Then run setup <sup>[<span style="color:#b60000">'''8a'''</span>]</sup>, click on the '''Add Pair''' button, which creates a pair of virtual ports, then click on the '''Apply''' button. There is no need to tick any of the tick boxes.
| |
| − |
| |
| − | In the setup window you will see '''CNCA0''' and '''CNCB0''' which are the newly created virtual ports <sup>[<span style="color:#b60000">'''8'''</span>]</sup> (If you should ever have the need to add more virtual ports, then the next pair will be '''CNCA1''' and '''CNCB1'''). The '''CNCA0''' is used in the '''<u>P</u>ath/Address:''' in VirtualBox virtual machine serial configuration <sup>[<span style="color:#b60000">'''10'''</span>]</sup> in this format '''\\.\CNCA0''' and the '''CNCB0''' is used in the '''Serial line''' in the Putty serial configuration <sup>[<span style="color:#b60000">'''11a'''</span>]</sup> just as it is.
| |
| − |
| |
| − | The com0com virtual ports process remains until you use the '''Remove''' button in the setup app, to remove them.
| |
| − |
| |
| − | ====Unix - tty0tty====
| |
| − |
| |
| − | You can get '''tty0tty''' from https://sourceforge.net/projects/tty0tty/files/ (the latest is currently tty0tty-1.2).
| |
| − |
| |
| − | Unpack the package '''tty0tty-1.2tgz''' to a folder; my OS was able to unpack it to '''/tty0tty-1.2/''', just by clicking on the package.
| |
| − |
| |
| − | It requires compiling, so navigate to the directory '''/tty0tty-1.2/pts''' (cd /tty0tty-1.2/pts) and open a terminal window (right click - '''Window''' - '''Terminal here'''). At the command prompt type '''make''' and shortly you should have an executable file in the '''pts''' folder.
| |
| − | Then still within the '''pts''' folder/directory, type '''./tty0tty''' at the command prompt to run <sup>[<span style="color:#b60000">'''8b'''</span>]</sup>. The output could be
| |
| − |
| |
| − | '''(/dev/pts/1) <=> (/dev/pts/2)'''
| |
| − |
| |
| − | or
| |
| − |
| |
| − | '''(/dev/pts/2) <=> (/dev/pts/3)'''
| |
| − |
| |
| − | it may vary. But whatever the left side is, such as '''/dev/pts/2''' will be entered into the '''<u>P</u>ath/Address:''' in the VirtualBox virtual machine's serial configuration <sup>[<span style="color:#b60000">'''10'''</span>]</sup> and whatever the right side is, such as '''/dev/pts/3''' will be entered into the '''Serial line''' in the Putty Serial configuration, instead of the default com or tty <sup>[<span style="color:#b60000">'''11b'''</span>]</sup>.
| |
| − |
| |
| − | I end the tty0tty virtual ports process, by using the '''Ctrl''' - '''c''' combination, but I would expect it to terminate when the terminal window is closed.
| |
| − |
| |
| − | There is another folder in the directory /tty0tty-1.2/module which also requires compiling. This will, when run, create several pairs of virtual ports, which remain until the OS is re-installed or upgraded. I have not used it or included it within this tutorial.
| |
| − |
| |
| − | ====Testing com0com and tty0tty====
| |
| − |
| |
| − | To test if it works, configure one instance of putty with '''CNCA0''' in Windows or '''/dev/pts/2''' in Unix and another instance of putty with '''CNCB0''' in Windows or '''/dev/pts/3''' in Unix, then run both Windows Puttys or both Unix Puttys and type into each terminal window. If the input from each terminal window is shown in the other terminal window (what is typed into Putty No1 should display in Putty No2, also what is typed into Putty No2 should be displayed in Putty No1), then you have a working virtual null modem cable.
| |
| − |
| |
| − | Now you can run your VirtualBox virtual machine and install ReactOS.
| |
| − |
| |
| − | '''Note:''' When you run your virtual machine with an installed OS, then make sure that there is no bootable media in any of your external drives (floppy, USB or CD/DVD), else the VirtualBox virtual machine will boot it instead of the installed OS.
| |
| − |
| |
| − | Now you can refer back to [[#The_ReactOS_debugger]]

| − | When you first created your bug issue report, you may have chosen the wrong words for the '''Summary''' (the summary becomes the title of the report) and you now want to change them for some that better describe your bug. In the '''Reported by me''' Issues window <span style="color:#006000"><sup>['''8''']</sup></span>, move your mouse pointer over the title and a pencil will appear at the end <span style="color:#006000"><sup>['''12''']</sup></span>, click on it and a cursor will appear in the title, so that you can edit the it. , When you have finished editing the title, press Enter on your keyboard.

| |
| − |
| |

| |
| − | The ISO files now come in the file format shown below.
| |
| − | <pre style="background:white;border:none;">

| |
| − | To do a search at the '''getbuilds''' page (https://www.reactos.org/getbuilds/) you only need the portion shown in the last line (above).
| |
| − |
| |
| − | Because of the way that Git tracks commits to the source tree, you can no longer use numbers in the same way that you could with SVN. So if you have tried a revision some days ago that was good and did not have the problem, then you can get the reference code (as shown above) from this '''good''' revision, then the reference code from the '''bad''' revision that exhibits the problem. Using these two numbers, you can then do a search at the '''getbuilds''' page (https://www.reactos.org/getbuilds/).
| |
| − |
| |
| − | To do a search, just uncheck all the boxes that are not required, put the two codes in the input box, with a dash between them, like so: '''48fe086-74cc915''', then click the search button. The search will then list all the revisions between and including the ones typed into the search input box.
| |
| − |
| |
| − | You are advised to copy paste the search results into a Text Editor, for further reference, unless you keep the page open with search result in.
| |
| − |
| |
| − | If you know that you have tested a good revision in the past, but cannot remember it's revision number, then you can list all the bootcd files at https://iso.reactos.org/bootcd/.
| |
| − |
| |
| − | We will assume that revision '''74cc915''' has a regression, so it is the ' '''bad''' ' revision, you will need to find a ' '''good''' ' revision.
| |
| − |
| |
| − | Using revision '''74cc915''' as the '''bad reference point''', using the list of ISO files, go back in increments of 100 or one week, installing and testing them, until you find the ' '''good''' ' revision. When you have found a ' '''good''' ' revision, that will be the '''good reference point''' and the last ' '''bad''' ' revision will become the new '''bad reference point'''. Now you have two reference points, a known ' '''bad''' ' revision and a known ' '''good''' ' revision.
| |
| − |
| |
| − | The guilty revision must be somewhere in between the two reference (revision) points!
| |
| − |
| |
| − | Next choose a revision that is half way between the two revisions, then test that revision to see if it is good, it will then become the new '''good reference point''', but if it is bad, it will then become the new '''bad reference point'''. Keep choosing a revision that is half way between the two, until you have found where the revision changes from good to bad; the bad is the guilty revision that regressed!
| |
| − |
| |
| − | Remember that the guilty revision is always between the last ' '''good''' ' revision and the last ' '''bad''' ' revision, until you have reached the point where they are next to each other.
| |
| − |
| |
| − | The old SVN ISO files are in this format '''r75098''' and are still available from https://iso.reactos.org/bootcd/, but are not now available at the '''getbuilds''' page (https://www.reactos.org/getbuilds/), because they are no longer being created.
| |
| − |
| |
| − | '''Note''' that the old revision numbers cannot be used in the search input box at the '''getbuilds''' page.
| |
| − |
| |
| − | It as been brought to my attention, that Git has some built in functions that do the same as in this guide. So if you have a local source tree, then you may like to read this '''https://git-scm.com/docs/git-bisect'''. '''Warning''': only use these git functions on your local source tree, because of what they do to the tree!

| − | <h2>A layman's guide - <span style="font-size:150%;color:#006080;">log2lines.</span></h2>
| |
| − |
| |
| − | In this tutorial there is also a Unix based subsection.
| |
| − |
| |
| − | You have created a Jira Issue for a bug, you are then asked to translate the addresses in the backtrace that are in the debug log.
| |
| − |
| |
| − | To do this you will need '''log2lines''', which comes with '''RosBE''', if you haven't already got '''RosBE''', then it can be down-loaded from Sourceforge http://sourceforge.net/projects/reactos/files/
| |
| − |
| |
| − | Before you down-load RosBE, create some folders on whatever drive you like and call them whatever you like. In my example, I have created a master folder on drive '''D:''', which I have called '''DebugWork''', this will contain all the files and folders.
| |
| − |
| |
| − | You will also need to have 7zip installed http://www.7-zip.org/download.html; Peazip will not work.
| |
| − |
| |
| − | Example:
| |
| − |
| |
| − | '''D:\DebugWork''' (this is the master folder, all the other folders and files are stored in this).
| |
| − |
| |
| − | '''D:\DebugWork\RosBE''' (install RosBE into this folder, but if you already have RosBE elsewhere, you will not need this).
| |
| − |
| |
| − | Put the debug log and the iso into the folder '''D:\DebugWork''' (in my example they are '''explorer-0.4.7-dev-557-g57cda5a.log''' and '''reactos-bootcd-0.4.7-dev-557-g57cda5a-x86-gcc-lin-dbg.iso''').
| |
| − |
| |
| − | Using the example from above, you would type this at the RosBE command prompt:
| |
| − |
| |
| − | <span style="color:#006080;">'''D:\DebugWork\RosBE></span>log2lines -m -d D:\DebugWork\reactos-bootcd-0.4.7-dev-557-g57cda5a-x86-gcc-lin-dbg.iso <D:\DebugWork\explorer-0.4.7-dev-557-g57cda5a.log> D:\DebugWork\explorer-0.4.7-dev-557-g57cda5a-new.log'''
| |
| − |
| |
| − | Explanation:
| |
| − |
| |
| − | <span style="color:#006080;">'''D:\DebugWork\RosBE>'''</span> ................................ The RosBE command prompt (which shows the directory of RosBE).
| |
| − |
| |
| − | '''log2lines -m -d''' ................................................ The command to start log2lines with two optional run-time commands.
| |
| − |
| |
| − | The command '''-m''' puts a '''<big>*</big>''' at the front of the translated line, and the command '''-d''' indicates that it is a directory or iso image.
| |
| − |
| |
| − | '''D:\DebugWork\reactos-bootcd-0.4.7-dev-557-g57cda5a-x86-gcc-lin-dbg.iso''' ....... The iso's directory path and name.
| |
| − |
| |
| − | '''<D:\DebugWork\explorer-0.4.7-dev-557-g57cda5a.log>''' ........ The debug log's directory path and name (you must include '''<''' at the front and '''>''' at the back).
| |
| − |
| |
| − | '''D:\DebugWork\explorer-0.4.7-dev-557-g57cda5a-new.log''' ... The directory where the new translated log will be written, with it's name.
| |
| − |
| |
| − |
| |
| − | If you have RosBE already installed elsewhere, then, using the same folder and files as in the example above, you would just start RosBE and at the command prompt, type: '''log2lines -m -d D:\DebugWork\reactos-bootcd-0.4.7-dev-557-g57cda5a-x86-gcc-lin-dbg.iso <D:\DebugWork\explorer-0.4.7-dev-557-g57cda5a.log> D:\DebugWork\explorer-0.4.7-dev-557-g57cda5a-new.log'''

| − | ===<span style="color:#006080">log2lines - '''Unix subsection'''</span>===
| |
| − |
| |
| − | When you install RosBE-Unix, there is no log2lines in the '''/RosBE/bin''' folder, like there is in a Windows install of RosBE, but, if or when you compile the ReactOS source, you will then find log2lines in '''/reactos/host-tools/''' folder. To use my example, it will be in '''/home/RosBuild/compiled/reactos/host-tools/'''.
| |
| − |
| |
| − | <small>See the '''Layman's guide - How to compile ReactOS - Unix subsection''' higher up this page, for instructions on how to install RosBE-Unix.</small>
| |
| − |
| |
| − | The log2lines command is in this format: '''log2lines options ISO <old log> new log'''
| |
| − |
| |
| − | Explanation:
| |
| − |
| |
| − | '''log2lines''' ........ Executes log2lines.
| |
| − |
| |
| − | '''options''' .......... Optional run-time commands for log2lines. '''-m''' Marks the translated line with an <span style="font-size:110%>'''*'''</span> and '''-d''' is for directory.
| |
| − |
| |
| − | '''ISO''' .................. This is the name and location of the ISO image that you used.
| |
| − |
| |
| − | '''<old log>''' ........ This is the location and name of the original log that you got for the bug.
| |
| − |
| |
| − | '''new log''' .......... This is the location and name for the modified log. It will be written with that name and at that location.
| |
| − |
| |
| − | <small>See also the explanation in the main section above.</small>
| |
| − |
| |
| − | Start RosBE and at the command prompt, type:
| |
| − |
| |
| − | '''/home/RosBuild/compiled/reactos/host-tools/log2lines -m -d /mnt/sda1/ReactOSDevelopment/debug-logs/bootcd-75458-dbg.iso </mnt/sda1/ReactOSDevelopment/debug-logs/SteamError2.log> /mnt/sda1/ReactOSDevelopment/debug-logs/SteamError2-new.log'''
| |
| − |
| |
| − | '''NOTE'''
| |
| − | For log2lines to work, you must either give the full path to the host-tools directory.
| |
| − | If you get any error message, for example '''log2lines: command not found''', then check that your paths are all correct.
