Where is the library for 'dlsym'

Question

I get this linker error:

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

Could you tell me where is the library on ubuntu 9.10 that contains the library for dlsym?

Thank.

Answer 1

On the dlsym(3)man page :

#include <dlfcn.h>

  ....

Link with -ldl.
