Question or issue on macOS:
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.
How to solve this problem?
Solution no. 1:
man 1 nm

For example:
nm -gU /usr/local/Cellar/cairo/1.12.16/lib/cairo/libcairo-trace.0.dylib
Solution no. 2:
Use otool:
otool -TV your.dylib
OR
nm -g your.dylib
Solution no. 3:
Use nm -a your.dylib
It will print all the symbols including globals
Solution no. 4:
Use Mach-OView for viewing all the Symbols in dylib
