Hi

I'm having trouble linking even testapps that are part of CERTI. I'm
building on ubuntu 15.10 using GCC 5.2.1. I suspect there is some
circular dependency but haven't yet investigated further. I get the
following:

The circular ref issue is a known problem but it has been handled
(not a definitive fix though) long time ago.

Which version of CERTI are you trying to build?

I got the same issue with CERTI-3.5.1 on a fresh ubuntu 15.10

Could you try to change version of compiler,
see recent thread about that issue here:
http://lists.nongnu.org/archive/html/certi-devel/2015-10/msg00005.html

It works properly with clang. Changing the gcc version is always
possible, but a boring solution. The issue only happens in the build of
the TestFedTime, so I disabled the build of it locally.

Moreover, the build with g++ success if I change the order of library in
-rdynamic (-rdynamic libRTI.. libFedTime => -rdynamic libFedTime
libRTI), but I do not find the way to force that using cmake. 

Add a target_link_libraries(libFedTime libRTI)?

We need a real fix for this circular ref issue but I have not time to work
on this for now.

Is this something that you are aware about or even have a fix for?
Should I try an experimental build to the Dashboard?

Yes see:
