a better fix, which i think will work on both linux and irix is to
call the dlopen() with a null pathname. the returned handle will then
be for the main program including the libraries linked dynamically. so
the correct version of SGLookupFunction() for unix should be (modulo
the other OSs):
inline void (*SGLookupFunction(const char *func))()
{
void *handle;
void (*fptr)();
handle = dlopen (0, RTLD_LAZY);
if (!handle) {
fprintf (stderr, "%s\n", dlerror());
exit(1);
}
dlerror(); /* Clear any existing error */
fptr = (void (*)()) dlsym(handle, func);
if ((error = dlerror()) != NULL) {
fprintf (stderr, "%s\n", error);
exit(1);
}
dlclose(handle);
return fptr;
}
tested only on linux as i don't have access to an irix system (but the
man page at
http://www.chemie.fu-berlin.de/cgi-bin/man/sgi_irix?dlopen+3 leads me
to believe it should also work on irix). hope this helps.
