Hi Mojca,

thank you for the hints.

I tried adding the former. It looks as if gcc 6 gets used.

The config fshows:

checking for gcc... /opt/local/bin/gcc-mp-6
...
checking whether /opt/local/bin/g++-mp-6 supports C++11 features by 
default... yes


thats a first good start!


Build fails with:

still a compiler error?

Well, first it needs to compile before running :)
