I am getting a linking error while compiling my c++ problem on MacOS X. I would like to find out if the sybmols exists on the .a file that I am linking with.

Answer 1

man nm

Nm displays the name list (symbol table) of each object file in the argument list. If an argument is an archive, a listing for each object file in the archive will be produced. File can be of the form libx.a(xo), in which case only symbols from that member of the object file are listed. ... etc

Answer 2

nm -g | c++filt

Mac nm没有demangle选项，因此您只需通过c++filt （一个demangler）运行输出。
