    Hi,

    I tryed to compile fortran code (FFTXlib) using xlf and spectrum mpi and got error:

    Unable to access module symbol file for module fft_scalar. Check path and file permissions of file. Use association not done for this module.

    My compile command:

    mpif90 -u -O1 -qsuffix=cpp=f90 -D__XLF -D__MPI -D__PARA  -I../include  -c fft_parallel.f90

    fft_scalar was built successfully.
    xlf version is 15.1.5.

    Error producing line in the fft_parallel.f90:

    USE fft_scalar ONLY cft_1z, cft_2xy

    Thanks,
    Vladimir

    I fixed it.
    The problem was that xlf can't recognize options -D__XLF -D__MPI -D__PARA.

    Yes, with XLF you need "-WF," before preprocessor options.  So -WF,-D__XLF -WF,-D__MPI -WF,-D__PARA
