Running the following sets the compiler to gcov: CC=/usr/bin/gcov cmake ../ This outputs: -- The C compiler identification is unknown -- The CXX compiler identification is GNU 7.1.1 -- Check for working C compiler: /usr/bin/gcov -- Check for working C compiler: /usr/bin/gcov -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - failed -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detecting CXX compile features -- Detecting CXX compile features - done -- Configuring done -- Generating done As you can see cmake definitely uses the CC environment variable. What is your OS? What do you set $CC to? What is the full commandline you use to call cmake? What happens if you set it the way I did? Regards, Micha
