Porting to OS/2: Install WLINK and WRC
Some OS/2 tools such as linker and resource compiler have some limitations. Fortunately, replacements for them are provided. They are wl.exe(linker) and wrc.exe(resource compiler) from Open Watcom project. wl.exe : http://home.earthlink.net/~steve53/OpenWatcom/wl_exe-20140527.zip wrc.exe : http://www.warpcave.com/OpenWatcom/wrc-static-build-20140417a.zip After downloading them, copy the executables from zip into any directory in your PATH. If you don't find any suitable place, then create directories x:\usr and x:\usr\bin. Copy them into x:\usr\bin. Of course you should add x:\usr\bin to your PATH env var. How can we use them ? You should set some env vars. For wl.exe, you should call gccenv.cmd with WLINK parameter. Do like this. x:\gcc\usr\bin\gccenv.cmd x:\gcc\usr WLINK Then, gcc will use WLINK when linking OMF object files and libraries. OMF is IBM's object module format. -Zomf flag is required for this. gcc -Zomf hello.c Then, gcc uses wl.exe instead of ...
