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 artic=
le http://www.perlmo=
nks.org/?node_id=3D673396 ,
after I changed dlop=
en flags to RTLD_LAZY|<=
/span>RTLD_GLOBAL in src/dynlib.c, the problem is solved.

 the RTLD_GLOBAL flag i=
n emacs's source code ?
thanks!
