Description Matthew West 2010-12-05 05:24:11 UTC
Created attachment 464800 [details]
Test program, compile with "gfortran -I /usr/lib64/gfortran/modules test_netcdf.f90"

Description of problem:

Compiling a Fortran 90 program that uses the NetCDF module netcdf.mod fails with a "Wrong module version" error. This is probably because the netcdf package was compiled with gfortran 4.4.3 (if I understand the koji logs [1] correctly), whereas the current version of gfortran in Fedora 14 is 4.5.1.

This should be fixed by rebuilding the package.

Version-Release number of selected component (if applicable):


How reproducible: Always

Steps to Reproduce:

1. Make the file test_netcdf.f90 (also attached) containing:
program test_netcdf
  use netcdf
end program test_netcdf

2. Run the command:
gfortran -I /usr/lib64/gfortran/modules test_netcdf.f90

Actual results:


  use netcdf
Fatal Error: Wrong module version '0' (expected '4') for file 'netcdf.mod' opened at (1)

Expected results:

Compiling succeeds.

Sorry for the additional noise, but I just checked in the source of gcc-fortran-4.4.3 and gcc-fortran-4.5.1 as distributed from GNU and the MOD_VERSION has indeed changed from '0' to '4' between these two versions.

I'm thus pretty confident that a simple rebuild is all that's necessary.

Do these rebuild packages fix it for you?


Comment 3 Matthew West 2010-12-06 07:05:41 UTC
Yes, that fixes it just fine.

My Fortran code compiles and links fine against this new build of netcdf, and passes its own test-cases (which are very reliant on netcdf).

Thanks for the fast response!
