I saw this message twice on two machines on two different days, end up using the same way to fix it.

Case 1: Samba

My Samba was down today, so I tried to start it manually:

/usr/local/etc/rc.d/samba start

And I got the following error message:

Removing stale Samba tdb files:  done
nmbd already running? (pid=1074).
Starting smbd.
/libexec/ld-elf.so.1: Shared object "libcups.so.2" not found, required by "smbd"
/usr/local/etc/rc.d/samba: WARNING: failed to start smbd

Initially, I thought the problem was about missing the file. So I did a search and soft-link it:

find / -name "libcups.so*"

Surprisingly, there is no such file in my system. I think I don’t have this file. So I tried to compile the Samba again:

cd /usr/ports/net/samba35
sudo make

and I got the following message:

===>  cups-client-1.4.8 is marked as broken: gnutls does not support threads yet disable the GNUTLS.
*** Error code 1

Stop in /usr/ports/print/cups-client.

Case 2: Upgrading Port

When I upgraded my FreeBSD system via portmaster, I found the following messages:

portmaster -Da

===>  cups-client-1.4.8 is marked as broken: gnutls does not support threads yet disable the GNUTLS.
*** Error code 1

Stop in /usr/ports/print/cups-client.

Initially, I tried to by-pass upgrading the cups-client using:

portmaster -Dai

However, it is very annoying to do it everyday, therefore I decide to solve this problem.

Solution

From the error message, it seems that the problem is caused by the additional option in cups-client: GNUTLS. So I decide to disable this option in the GNUTLS:

cd /usr/ports/print/cups-client
sudo make config

Uncheck “GNUTLS: Build with GNUTLS instead of OpenSSL”

and try to compile it again:

sudo make

Now re-run the portmaster:

sudo portmaster -Da

The problem is gone.
