Can't open module file ‘netcdf.mod’

[burkzdemir]

Dear developers,

I am getting an error during compilation. Error is below and I attached my config file.

mod_pars.f90:28:5:

use netcdf
1
Fatal Error: Can't open module file ‘netcdf.mod’ for reading at (1): No such file or directory
compilation terminated.
Makefile:176: recipe for target 'mod_pars.o' failed

Best,

Dear Burak,

the error is due to a fail in the internal compilation of the netcdf library.
You can have a look to these threads:

I tried to make netcdf as suggested in the forum and I obtained this error:

checking for gcc... mpicc
checking whether the C compiler works... no

Dear Burak,
it seems your C compiler is not working properly, can you compile other codes in C?
please check that your compiler is installed properly.
You can send the config.log file found in the netcdf directory:
/yambo-master/lib/netcdf/netcdf-c-4.7.4'

in order to see if it is possible to understand what is going wrong.

Best,
Daniele

Yes, I can compile c programs. I attached the config file.

Best,
Burak

Dear Burak,

this happens because the hdf5 library should be compiled before compiling netcdf.

Dear Daniele,

I compiled hdf5 and then I tried to compile netcdf but this time I got this error:

configure: error: Can't find or link to the z library. Turn off netCDF-4 and DAP clients with --disable-netcdf-4 --disable-dap, or see config.log for errors.

Best,

[Daniele Varsano]

Dear Burak,

probably it is a matter of CPPFLAGS and LDFLAGS which are not pointing to the hdf5 libs.
See e.g here:
https://www.unidata.ucar.edu/support/he ... 12453.html

You can try to reconfigure yambo (now hdf5 should be detected) and recompile.

Best,

Daniele

Dear Burak,

indeed, in some cases I had to compile zlib by myself (not too difficult, actually).
Once that is in the path, I used the following flags to compile hdf5:

Code: Select all

./configure \
   --prefix="/opt/hdf5/1.8.19-gnu/" \
   --enable-parallel \
   --enable-fortran \
   --enable-fortran2003 \
   FC=mpif90 \
   CC=mpicc \
   CXX=mpic++ \
   CPP="gcc -E"

HTH
