can I check out the class definition from binary?

[lin q]

Hi,
  I have a program built on Linux and having problem in debuging it in GDB. 
I am suspecting that its symbol table is not built as expected, meaning the 
debug info is not complete.

  I wonder how to use the binutils to check that. For example I now there is 
a class C1 defined in lib1.so, then how I can print out the definition? I 
just run "nm", but it only print out the names of the symbol table, it does 
not list the class definition.

Thanks.
