#2196: Compilation error when running command ./simfactory/bin/sim build --mdbkey

Comment (by anonymous):

 Most of the lines are warnings and can be ignored. However there is one
 g++: internal compiler error: Killed (program cc1plus)
 which is an actual error. The output suggest filing a bug report with the
 gcc team. However giving that you are running this in a VM my first
 suspicion would be that you are running out of memory (in which case the
 OS will kill one process more or less at random).

 So I would try two things:

 # provide the VM with more memory (at least 2GB, better 3GB)
 # compile serially ie use --mdbkey make 'make -j1' which will also reduce
 memory consumption since only one g++ process (g++ is the most memory
 hungry of gcc, g++ and gfortran) will run in parallel
