current dlopen flag is RTLD_LAZY,

//src/dynlib.c

dynlib_handle_ptr
dynlib_open (const char *path)
{
  return dlopen (path, RTLD_LAZY);
}

my module will also load other shared libs, I got some error like symbol undefined,

I found this article http://www.perlmonks.org/?node_id=673396 ,

after I changed dlopen flags to RTLD_LAZY|RTLD_GLOBAL in src/dynlib.c, the problem is solved.

could emacs developer consider to add the RTLD_GLOBAL flag in emacs's source code ?

Reading the manpage of dlopen, I don't think this flag should be added. Emacs modules should typically export only two symbols (plugin_is_GPL_compatible and emacs_module_init), which aren't useful outside Emacs.
