That is curious. But all this is so old and this Fortran95 had never worked in par4all, only Fortran77. So just skipping the compilation would be fine.

You have to find a way to remove --enable-fortran95 from the setup.

Oh, actually it looks like some people have solved the issue in an alternative way on http://www.fractalforums.com/programming/omp-vs-par4all

They could make a pull request... :)

Thank you. It worked :+1: . I am working with C parallelization, so currently I have removed --enable-fortran95 from the setup file. Now Par4all is installed successfully.
