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.


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.


You can use WinMerge to see changes in source code visually. This is particularly useful for submitting and reviewing patches.

  1. Create a new directory. For example C:\mingw.
  2. Extract the files mentioned above in the directory you just created. It is important that you extract last because it overwrites the buggy gcc.exe from
  3. 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).
  4. 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.
