So I've been trying to get dynamic libraries to work in my XCode project under Mac OS X. So far no joy.
I am able to load the dylib file, but when I call dlsym to get the function pointer, it returns 0 and dlerror says symbol not found.
So I am wondering if there is a simple way to list the symbols that are exported from a dylib file. Any ideas would be great.
MK.
man 1 nm
https://developer.apple.com/legacy/library/documentation/Darwin/Reference/ManPages/man1/nm.1.html
For example:
nm -gU /usr/local/Cellar/cairo/1.12.16/lib/cairo/libcairo-trace.0.dylib
Use nm -a your.dylib
It will print all the symbols including globals
Use Mach-OView for viewing all the Symbols in dylib
