undefined reference to 'gdbm_open'

Castro · 06-11-2003, 11:35 AM

Does anyone know why this would compile in one program but not in another?

Have this in my file:
#include <gdbm.h>

One program which has the same identical file compiles fine on the same RedHat 7.3 system. However, I just added it to another program and my new program gives me undefined references for all of the gdbm functions as if the include weren't there?

TIA for any help.

Figured out the problem, if anyone is curious:

My Makefile run by the 'make' command was missing the -lgdbm flag.

I added the following in my configure.in to check for gdbm:

AC_CHECK_LIB(gdbm,gdbm_open,,AC_MSG_ERROR("Required: gdbm database libraries"))
AC_CHECK_HEADER([gdbm.h],,AC_MSG_ERROR("Required: gdbm headers"))

Once that was included, if gdbm is installed properly, it will add that flag where needed after autoconf->configure->automake->make and also make sure the library path is setup as well.
