I am trying to compile code with gfortran. One of the first things that happens in compilation is creation constants.mod. Soon after, he gfortrantells me:
Fatal Error: Cannot read module file ‘constants.mod opened at (1), because it was created by a different version of GNU Fortran
Now here's what: this module file is created by the one gfortranthat is trying to read it. gfortrancreates the thing itself, and then after 1 second thinks that the file was created by some other version! Any idea what is going on here?
You might want to see the compilation command:
mpif90 -c -O3 -ISDF/FORTRAN/include -I/usr/include -Iobj -Jobj -o obj/shared_data.o src/core/shared_data.F90
shared_data.F90contains the constantsmodule at the top of the file.
EDIT: Here's a compilation command followed by a full error message:
$> mpif90 -c -O3 -ISDF/FORTRAN/include -I/usr/include -Iobj -Jobj -o obj/shared_data.o src/core/shared_data.F90
src/core/shared_data.F90:67:6:
