I am programming in Fortran 90 using GFortran and I'm having troubles with Modules. When I compile the code below, I get the following error:
Derivatives.f90:7.16:
Included at C:\Users\dchalhub\Dropbox\Doutorado\#Tese\New folder\main.f90:1:
Use Mesh
1
Fatal Error: Can't open module file 'mesh.mod' for reading at (1): No such file or directory
gfortran.exe: Internal error: Aborted (program f951)
Please submit a full bug report.
See <http://gcc.gnu.org/bugs.html> for instructions.
So, the 'mesh.mod' file is not created. But when I remove the first two lines: 'include 'Derivatives.f90'' and 'include 'Poisson.f90'' the module is created without any problems.
After the mod file is created, I put back the first two lines, compile the code again and it works perfectly.
include 'Derivatives.f90'
include 'Poisson.f90'

I don't know why but there is something wrong with compiling multiple files with modules. Does any one know what should I do to make it work properly?
