Hi. These is a how-to for people who want to make the GRX win32 version, but don't know about the mingw compiler: 1.- First, download the mingw distribution: ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/mingw32/gcc-2.95.2/ gcc-2.95.2-msvcrt.exe ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/mingw32/gcc-2.95.2/ mingw32-docs-html.exe ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/mingw32/gcc-2.95.2/fixes/ quote-fix-msvcrt.exe 2.- Create a \MINGW dir and decompress the three files on it (The files are not instalers, only auto-decompress files) 3.- Create a \MINGW\SETVAR.BAT file with the line: SET PATH=C:\MINGW\BIN;%PATH% 4.- Open a DOS window and execute \MINGW\SETVAR 5.- Go to the dir you have the GRX 2.4 distribution. Go to the src subdir and execute "make -f makefile.w32" Go to the test subdir and execute "make -f makefile.w32" Go to the test\bgi subdir and execute "make -f makefile.w32" Hope this help, M.Alvarez
