    I tried installing on my new computer by starting the install_fortran batch file and it successfully installed up to geanyins.exe. However, it then showed an error saying


    use omp_lib
    Fatal Error: Can’t open module file ‘omp_lib.mod’ for reading at (1): No such file or directory
    compilation terminated.

    What’s really weird is that this error did not happen in my other old computers. Could you help me out solving this issue?

    Much appreciated,

    Hi Cheol,

    sorry for not getting back to your earlier. In fact I am a bit puzzled by this. It seems that the version of Fortran installed on your computer does not contain openMP, which is weird. To dig a little deeper into this problem, I would have to know a little bit more about your computer (type and operating system).

    If you want a quick fix for this, you can navigate to the folder toolbox in the installation directory. Open the file and then do the following:

    1. Move to line 791 and comment our the line use omp_lib
    2. In line 797 replace omp_get_wtime with cpu_time
    3. Do the same in function toc right below (lines 809 and 835).

    Now try to run the installation routine again and tell me whether it works.
