How to find out what are in .so lib file on linux?

I tried "ar t libABC.so" which does not work. It works on cygwin for .a files.

What else command can I use?

Thanks a lot!

ar t works on Linux too -- for *.a files.

For .so files, you can use nm. Just "nm foo.so" will list all the symbols.

Thanks EFH

I tried it, and it gave me many symbols I am not quite sure what is what...

Does that mean there are no .o files inside .so any more?

Thanks!

No, I don't believe there are.
