Ivan's C library

Hercules390 - General mailing list
Hi Ivan.

I believe many years ago, like
around 15 years ago, you were
working on a C library for CMS,
and maybe also MVS.

I'm not sure anything was ever
released. Would it be possible
for you to package up your work
and release it (including either
a PD notice or whatever your
copyright restrictions are) just
for posterity?

The only open source C libraries
for the IBM mainframe (any operating
system) that I know of are:

PDPCLIB (started by me):
http://pdos.sourceforge.net/

LIB390 (from David Bond of Tachyonsoft):
https://groups.yahoo.com/neo/groups/hercules-os380/files/lib390.tar.gz


Also GCCLIB (CMS derivative of
PDPCLIB by Bob O'Hara).

Also John Hartmann has GCC390
which I think is a derivative of
GCCLIB for z/CMS, available here:

https://github.com/jphartmann/cmslib

He also has this interesting tool:
https://github.com/jphartmann/gas2asm

which may open up the possibility of
using the S/390 (not i370) target of
GCC 4 (not GCC 3.4.6 and lower)
to produce 31-bit and 64-bit load
modules that run on z/OS and MVS/380.
GNU Cobol is probably dependent
on GCC 4 working too.

Not sure if Waterloo C for MUSIC/SP
provides runtime source.

Also not sure if the C compiler that
comes with MTS (called "c89") has
open source runtime.

I don't know if the C compiler ported
to MVS by Dennis Ritchie and co in
the 1970s was ever released.

I think Open Watcom contains some
code regarding an MVS target, but
I don't think it is operational any
more, and I don't think there was a
mainframe C library either.

Any other contenders?

Thanks. Paul.
