Re: dlsym(...) and Intel Macs



Have you tried removing one of the prefixing underscores? It could be that the prefixing rules have changed, though I haven't heard anything to that effect..

Does dlsym(...) not work the same on Intel Macs? I have some symbol loading code that works just fine on PowerPC Macs, but on Intel Macs, it returns NULL. Here is a line.

int *debug_addr = (int *)dlsym(mainHandle, "__debug_level");

This loads the symbol named `__debug_level'. This code is executed from a dynamically-loaded bundle, and it loads the address of the symbol from the main executable. On PowerPC, I get the address you'd get by doing `nm' on the executable. On Intel Macs, I get NULL. Any ideas what's happening here?
