Hi,

I tried to create an framework from some ancient sources.
They compile OK, but with CW 9.1 I get the following link error:

Link Error : undefined: 'environ' (non lazy ptr IL)
Referenced from 'pvmputenv' in pvmcruft.c

environ is defined as

#ifndef IMA_WIN32_WATCOM
extern char **environ;
#endif

As it is supposed to be an framework, I use dylib1.o as the "runtime"
library. How can I get my framework to link?

Regards,
Tom_E

Use
#define environ **_NSGetEnviron()
instead of the extern definition. _NSGetEnviron() is defined in
/usr/include/crt_externs.h.

Hope this helps,
Eric
