We had a lot of problems with netcdf on x86_64 using gfortran. What I
ended up doing is:
- getting a binary distribution of netcdf from the homepage
- deleting the netcdf directory provided by amber and creating a
symbolic link to the binary distribution directory
- changing the amber Makefiles to not compile netcdf
The following should do it.
cd $AMBERHOME/src
mv netcdf netcdf-dist
ln -s /path/to/netcdf netcdf
patch -p0 -N -r patch_netcdf_rejects < netcdf.patch
This is the patch:
