Bug 506206

Description of problem:

libslapd is not linked with -lrt, which provides the semaphore functions.
From Rich Megginson:
This is usually fine, since ns-slapd (the executable) is linked with -lrt, so that at runtime all of these references are resolved,  But Debian uses -Wl,-z,defs which forces all references to be looked up at link time.  We should fix this in 389 - please file a bug against 389.  In the meantime, you could either turn off -z,defs, or figure out how to link libslapd with -lrt.

Version-Release number of selected component (if applicable): 389-ds-base-1.2.1


How reproducible: Happens every time.


Steps to Reproduce:
1) 389-ds-base-1.2.1 package - Initial debianization:

root@dirserv1:~/project-389/389-ds-base-1.2.1# dh_make -e morenisco -c gpl -f ../389-ds-base-1.2.1.tar.gz

Type of package: single binary, multiple binary, library, kernel module or cdbs?

3) I tried to build the package with the following command:

root@dirserv1:~/project-389/389-ds-base-1.2.1# dpkg-buildpackage -rfakeroot

The generated output is too long, and the latest part is the following:
