Build Environment
- How to Cross Compile to MinGW on Linux/BSD
Required files
For latest releases go to http://www.mingw.org/download.shtml and download the following files:
- MinGW-3.1.0-1.exe
- gcc-core-3.3.3-20040217-1.tar.gz
- gcc-g++-3.3.3-20040217-1.tar.gz
- w32api-2.5.tar.gz
- binutils-2.15.94-20050118-1.tar.gz
- NASM
If you wish to use GCC 3.4.1, instead, please see the GCC 3.4.1 Issues page. Please note that newer binutils packages namely 2.15.9x have problems with forward linking export functions and therefore will not build ReactOS properly.
You can also try the ReactOS Build Environment Setup - it includes everything (compiler, linker, ...) which is needed to build ReactOS:
Building ReactOS
Run the make file from the root directory of ReactOS. In order to build a bootable ISO image, you must first build freeldr then run "make install" ; next you must run "make bootcd" from the root ReactOS directory. The ISO image will be located in the root ReactOS directory when it is finsihed.
Installation
First run MinGW-3.1.0-1.exe then unpack the other tarballs into the directory which you had installed MinGW.
Optional stuff
Subversion Client
Get yourself a Subversion client and download the sources from the Subversion repository.
Patching
You can use WinMerge to see changes in source code visually. This is particularly useful for submitting and reviewing patches.
- Create a new directory. For example C:\mingw.
- Extract the files mentioned above in the directory you just created. It is important that you extract gcc-update.zip last because it overwrites the buggy gcc.exe from gcc-2.95.3-fastcall.zip.
- In your install directory (C:\mingw in this example), you fill find the file mingw32.bat. Change the line that updates the PATH variable according to your install directory (add C:\mingw\bin in this example).
- Run mingw32.bat before you want to use mingw. You can call it from autoexec.bat or you can call it whenever you open a shell window.
