Hi Bernard,
I couldn't reproduce the problem with Mac OS X 10.8.0. I managed to
build a standalone application fine but I've committed the patch as you
suggested.
Best regards,
David

Hello,
poly builds and runs fine on mac, but standalone applications do not work
(on OSX 10.6.8, at least). When running aplications, one gets:
dyld: Symbol not found: _environ
Referenced from: / ... /lib/libpolyml.4.dylib
Expected in: flat namespace
in / ... /lib/libpolyml.4.dylib
Trace/BPT trap
It happens that variable environ cannot be accessed directly from shared
libraries;
there is a paragraph about that in the environ(7) man page (last
paragraph).
The fix is to replace in file libpolyml/process_env.cpp
the line:
extern char **environ;
by:
#if __APPLE__
#include <crt_externs.h>
#define environ (*_NSGetEnviron())
#else
extern char **environ;
#endif
Best,
Bernard.
