I tried using backtrace_symbols from a framework of mine, and the function names were wrong. They were names that were probably in the framework somewhere, but not code that was actually being used. This was a debug build, full debug symbols, not optimized, not stripped. I tried changing the debug info format from Dwarf to Stabs and it made no difference. What might I be missing?

Having received no response to that question, I looked a little deeper. I see that the key is dladdr, which backtrace_symbols uses to get the symbols. And I find that dladdr starts working the way I expect when I uncheck the "Symbols Hidden by Default" code generation option for gcc. So, is that just the way it works - that when the dladdr docs say it finds the "nearest runtime symbol", that means exported symbol? _______________________________________________ Do not post admin requests to the list.
