Where is the library for 'dlsym'

Question

I am getting this linker error:

system/core/libacc/tests/main.cpp:42: error: undefined reference to 'dlsym'

Can you please tell me where is the library on ubuntu 9.10 which contains the library for 'dlsym'?

Thank you.

Answer 1

From the dlsym(3) man page:

#include <dlfcn.h>

  ....

Link with -ldl.
