Fortran sources but no Fortran compiler found
You should install a Fortran compiler, e.g. gfortran (via MinGW/Cygwin on Windows). See here for details. A C++ compiler won't help here.
MinGW includes gfortran as part of the distribution, with Cygwin, you need to install the package gcc-fortran.
After the installation, add the path to its binary to the system PATH.
Alternatively, you can purchase a commercial Fortran Compiler, e.g. from Intel.
