I’m trying to compile fortran code given to me by a labmate to run

  • 0

I’m trying to compile fortran code given to me by a labmate to run some analyses. The program involves calling MATLAB scripts to calculate certain things. The files he gave me were set up to run on a different computer and I’m trying to get them working on mine. I’ve changed the ACML and MATLAB library paths to the corresponding ones on my computer.

The error I’m getting is:

I’ve googled the crap out of this and haven’t had any luck getting it fixed. If anyone has any ideas for me to try, I’d greatly appreciate it.

    Talked the the guy who made it originally. It was an issue with the version of gfortran used. I was using gfortran 4.6.3. He said he used 4.4.5 when he last successfully used it. I installed gfortran 4.4 and compiled with no issues. On to the next issue I encounter!
