That could get you going. Although if you can get a small zNALC LPAR going
IBM's C/C++ compiler is darn close to zero price.
Timothy,
Have you (has anyone?) actually used GCC, the Tachyon z/Assembler, and LIB390
to port any significant open source software to z/OS USS? Which packages?
I'm not saying that this project is not doing excellent work, but I'm skeptical that its
ready for prime time. According to the website for "LIB390" (the OS390 GLIBC):
- "well over half of the C library functions are implemented..."
- "Support for the C++ language will require two major enhancements"
- Debugger support is not available
The referenced SHARE Presentation: http://www.tachyonsoft.com/s8131db.pdf is from 2002.
Its not clear if this project is very active.
I agree 100% with John McKown: having a good "bootstrap" GNU tool chain for
z/OS USS would enable many important packages to be ported to z/OS. (for more see:
http://oss4zos.org )
But at this point, I think that building a bootstrap GNU toolchain on top of the IBM z/OS C/C++ compiler is the best way to go.
