Dear Sir,

While compiling Yambo 4.3.1, I find this error:

I have also attached the config.log file for your perusal. I would be glad if you please let me know the bug...

With regards,
Sitangshu

Forgot to mention that I have gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.10)

Dear Sitangshu,
it seems you have something odd in the definition of the C compiler when compiling the netcdf library.
You can try to define the compiler explicitly in the configure line:
./configure CC=gcc CPP='gcc -E'

check also the the MPI wrapper mpicc and mpifort points to the correct compilers.

Best,
Daniele

Thank you Daniele,let me check with this..

Sitangshu

Dear Daniele,

The problem still remains.
I tried to install the next lower version: 4.3.0 and it surprisingly worked. I am sharing the config.log file of this version..
Please check..

Sitangshu

Dear all,
I met the same problem and for 4.3.0 it it is OK.
What the problem could be?

Thanks!

Dear Shudong and Sitangshu,
we have spotted the problem and sovled it (Thanks to Andrea Ferretti).
You can easily fix it by changing this line in the Makefile.loc file in lib/netcdf and lib/netcdff
by setting it as:
LIBPATH=$(libs_prefix)/$(fc_kind)/${fc}/${netcdf_ver}/${hdf5_ver}
note that in the current file the latter string /${hdf5_ver} is missing.

Best,
Daniele

Thanks Daniele,

This is working now.!

With regards,
Sitangshu
