Error while compiling PFLOTRAN with standard Linux packages

[Paulo Herrera]

Hello everyone, 

I am new to this list.

I have been running PFLOTRAN in Amazon AWS with success during the last few days, BUT:

I tried compiling PFLOTRAN on a new Amazon machine (instance) using AWS Linux (which seems to be a RedHat/CentOS modified version). 

I was able to compile PETSC with the standard packages (blas/lapack/mpich) and  downloaded HDF5. However, I get an error message about type mismatch for a call to MPI_Allreduce from the file option.F90 in PFLOTRAN (please, see attached screenshot). 

Has anyone experienced a similar problem? 

Recompiling PETSC with --donwload-mpich  solved the problem. However, it would be nicer/easier/faster using the standard packages.

Thanks,

Paulo
