script:
    # unfortunately, getting everything to compile is not a walk in the park... 
    # -osx gives massive amounts of error messages *without* "-std=c++11", leading log files > 4MB, which causes travis to fail..
    # -linux has g++ 4.8.4, and there compiling *with* "-std=c++11" leads to errors...
    # 
    # For now, I am resorting back to the c++99 standard, but try to workaround the large log files with a script
    # found online...
    #
    # In case we want to try the other route again (surpressing warnings), this is what I was doing:
    # export CXXFLAGS="-std=c++11 -Wno-unused-local-typedefs -Wno-unused-variable -Wno-unused-but-set-variable -Wno-redeclared-class-member" &&   ./configure && make
