How to print a list of symbols exported from a dynamic library

问题

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.

回答1:

man 1 nm

For example:

nm -gU /usr/local/Cellar/cairo/1.12.16/lib/cairo/libcairo-trace.0.dylib

回答2:

Use otool:

otool -TV your.dylib

OR

nm -g your.dylib

回答3:

Use nm -a your.dylib

It will print all the symbols including globals

回答4:

Use Mach-OView for viewing all the Symbols in dylib
