Re: [Genfit-forum] Problem compiling GENFIT

Hi Federico,
can you post the actual error output of CMake / GCC ? Please give the 
output as verbose as possible ( for GNU make: "make VERBOSE=1" )

Greetings,
Thomas

I get an error message about the C++ compiler not being able to compile a simple test program. I'm confused about the default setting /usr/bin/c++, where is GCC supposed to be used? More generally, which files have to be modified with cmake in order to change compiler?
