2. Tools required

I have tried to reduce the number of external tools, but when looking back it seems I were not very successful. At least I managed to get everything working with the native CMD.EXE shell only. However, there is still plenty of software required. Most of this software is available from hobbes.nmsu.edu or ftp.leo.org via anonymous FTP. The following shopping list shows what you will need:

• gcc EMX/gcc emx 0.9C patch4 or later (0.9d preferred!)
• gzip GNU zip/unzip
• tar GNU tar
• patch Larry Wall's patch utility (attention: incompatible tool with same name in OS/2)
• install BSD/GNU install
• rm,mv,cp GNU file utilities
• tee,.. GNU shell utilities
• groff GNU nroff/troff
• sed GNU sed stream editor
• grep GNU grep
• gawk GNU awk
• make GNU make 3.71/3.72 (use the one from Xprog.zip!)
• flex GNU flex
• bison GNU bison
• m4 GNU m4
• find GNU find (attention: incompatible tool with the same name in OS/2)

If there is no version number given, any new version will do. Particularly critical is only EMX/gcc and GNU make. Note that the second GCC implementation which might still be available from some archives is NOT compatible.

Furthermore, you need the X11R6.9 sources. These are available from the common X.Org repositories. Look into a directory which is often named /pub/R6.9.
