I was wondering why this error is occurring and how to fix it? A quick google search says there might be something wrong with my code, but since I haven't modified the source code at all I doubt that. I'm using gcc 4.4.2. Thanks.

So I've been stuck on this issue for the better part of two weeks. I've tried to build the model on multiple systems with different configurations, with no luck.

Would anyone mind sharing their configurations settings if they are using gfortran/gcc compilers to build the model?

I also have an issue when using MPI, it says the C compiler cannot build executables. Although I don't think this is an issue when i try to build the model using MPISERIAL.

Thank you for any asisstance you can give.
