Compiler issue?!

[fsimkovic]

I'm running into trouble installing CCMpred on Ubuntu 16.04 LTS. My cmake and make outputs are below.

Have you @sseemayer got any idea what the problem is? Thanks in advance!

Sorry about that @fsimkovic , this is a bug in the conditional compilation of CCMpred that occurs if the machine has libjansson installed but not libmsgpack - can you check if 414f467 fixes your problem?

Thanks @sseemayer, that fixed the problem!
