Hi
Ok I've tried the stuff below.

I've made a new IOC with makeBaseApp.pl -t cmlogtest
and then makeBaseApp.pl -i -t cmlogtest

ok
then I've rather added CMLOG = /epics/cmlog to configure/RELEASE
I've made simlinks so that CMLOG_ARGH can be linux-x86 so I don't need
that line.

Added the other stuff to the makefile as specified.

Now if I compile directly I get output:

-D_XOPEN_SOURCE=500        -D_X86_  -DUNIX  -D_BSD_SOURCE -Dlinux

make[2]: *** [install.linux-x86] Error 2

ok this doesn't make sense at all!
Because cmlog is statically linked. So why can adding this produce some
or other reference messup.

ok so I've added two include lines to the source file cmlogtestMain.cpp
#include "cmlogClient.h"
#include <unistd.h>

now I ran make clean and then make
See attached file for output.

Maybe cmlog is just not meant for me :)
