compiling without -O2 ld shared lib errors

Thanks. Thought this might be the case.
However, that doesn't explain why it magically when compiling with -02. Are linker rules relaxed when they see code compiled with -O2? It doesn't make a lot of sense to me.
Unless maybe -O2 removes the entire function that references this symbol, because it is is not used anywhere... Hmmm.... Might have worked this out myself :-)
./kdc/digest-service.c:
=== cut ===static voidntlm_service(...){[...]ret = heim_ntlm_calculate_ntlm1(...)[...]}
[...]
intmain(int argc, char **argv){[...]#if __APPLE__** *{** * * *heim_sipc mach;** * * *heim_sipc_launchd_mach_init("org.h5l.ntlm-service",
** * * * * * * * * * * * * * * * * *ntlm_service, context, &mach);** * * *heim_sipc_timeout(60);** *}#endif[...]}=== cut ===
Am thinking the best solution might be to wrap the entire*ntlm_service function with the same*#if __APPLE__ ... #endif, as that appears to be the only reference to*ntlm_service, and I think the static definition means it can't be referenced externally.
