This article is from the 3b1 computers FAQ, by John B. Bunch with numerous contributions by others.
In theory, anyway, most of what you need from the Development Set can be obtained elsewhere. There are at least five things that you need to do C programming on the UNIX PC:
o a C compiler
Use GCC (binary available in languages/gcc-gas.tar.Z on OSU-CIS)
o an assembler
Use GAS (binary available in languages/gcc-gas.tar.Z on OSU-CIS)
o a linker/loader (/bin/ld)
This is included in the Foundation Set.
o system header files
Alex Crain (alex@umbc3.umbc.edu) has created a set of ANSI header files which appeared in Volume 1, Issue 49 of comp.sources.3b1, with one patch.
o libraries
This is the tough one. There are a bunch of libraries that come the Development Set which would be difficult to replace. One of the most important (/lib/libc.a) is on the Encryption Set disks in the Foundation Set. Supposedly FIXDISK2.0 contains one or more updated libraries. The network and OSU remain good sources for strings, POSIX, dirent, etc. libraries. Of course, there are other libraries like /lib/libm.a (math) and /lib/libld.a (COFF access) which might be more difficult to replace.
This writer hasn't actually heard of anyone actually pulling this feat off, but sometimes he has trouble paying attention. ("Eh?")
