Regarding the sem_post problem, here is an old email from Tomasz
Gebarowski which is interesting because it states that he had a
sem_post issue with cdp.so which he solved by modifying the
modules/cdp/Makefile. Now if we skip forward to right now, I notice that
cdp.so COMPILE and LINKS for me with no errors and I also notice that
Tomasz' fix is in place, but other ims modules that also use semaphore do
NOT link properly for me in ubuntu and are exhibiting the same *undefined
symbol: sem_post* error Tomasz had years ago in his ubuntu compiles. I
think (hope) this may be more than coincidence that these things are
related??? I have tried Tomasz' fix with an ubuntu compile but I still get
the sem_post error. I still think he is on to something here and I am NOT
modifying the Makefile correctly. Any suggestions on specifics to test this
theory are greatly welcome. Here is Tomansz' email.....

Hello,
I've just googled some old post from October 2011, describing an issue
with crashing I-CSCF and S-CSCF. The log message was something like:

 0(2142) ERROR: load_module: could not open module /opt/OpenIMSCore/ser_ims/
 modules/cdp/cdp.so>: /opt/OpenIMSCore/ser_ims/modules/cdp/cdp.so:
undefined symbol: sem_post

I managed to fix this issue on Ubuntu 11.10. It seems that UBUNTU,
required linking cdp.so against pthread. Below you can find a simple patch:

Index: modules/cdp/Makefile
===================================================================
--- Makefile    (revision 1175)
+++ Makefile    (working copy)
@@ -20,7 +20,7 @@
  endif

  DEFS += -I/usr/include/libxml2
-LIBS += -L$(LOCALBASE)/lib -lxml2 -lrt
+LIBS += -L$(LOCALBASE)/lib -lxml2 -lrt -lpthread

  include ../../Makefile.modules
===================================================================
