Hi all yamboers!

I have an issue in compiling the last version 4.2.1 and linking the LibXC. Indeed with or without explicity activating the libxc support, yambo "pretends" to look for the LibXC and to install them.

So I am blocked on this point.

Here what I get as error message after the

Code: Select all

 make yambo

or

Code: Select all

make get_extlibs + make ext-libs

:

Code: Select all

chmod u+x /model/fiori/CODES/yambo/yambo-4.2.1/lib/external/intel/mpifort/lib/*xc*.a
chmod: cannot access '/model/fiori/CODES/yambo/yambo-4.2.1/lib/external/intel/mpifort/lib/*xc*.a': No such file or directory
Makefile:49: recipe for target '/model/fiori/CODES/yambo/yambo-4.2.1/lib/external/intel/mpifort/lib/libxc.a' failed
make[1]: *** [/model/fiori/CODES/yambo/yambo-4.2.1/lib/external/intel/mpifort/lib/libxc.a] Error 1
make[1]: Leaving directory '/model/fiori/CODES/yambo/yambo-4.2.1/lib/libxc'
Makefile:141: recipe for target 'ext-libs' failed
make: *** [ext-libs] Error 2

Here is my configure:

Code: Select all

./configure FC=ifort  CC=icc  CPP="icc -E" MPIFC=mpifort  --with-iotk-libs="/model/fiori/CODES/Quantum-espresso/qe-6.2.1/qe-6.2.1_ifort_fftw3/iotk" --with-scalapack-libs="-L/x86_64/INTEL/composer_xe_2015.2.164/mkl/lib/intel64 -lmkl_scalapack_lp64" --with-blacs-libs="-L/x86_64/INTEL/composer_xe_2015.2.164/mkl/lib/intel64 -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lmkl_blacs_openmpi_lp64" --with-fft-libs="-mkl"

and attached there is the config.log
For sure I am missing some steps, but I couldn't find the proper solutions.
Sorry to bother if there is already a reply in the forum I did not see.

With the best

Ciao Feffe,
libxc are now mandatory, but yambo should download and install them for you.
I suggest you to do a make clean_all and recompile from scratch.
You should see at some point yambo downloading the libxc and netcdf as well. Check if your machine allows for the download of the external libs (wget).

Hi Daniele.

Libs are installaed and compiled!

Now I realized that the libs are installed here

Code: Select all

/model/fiori/CODES/yambo/yambo-4.2.1/lib/external/intel/mpifort/lib64

while yambo looks for them in

Code: Select all

/model/fiori/CODES/yambo/yambo-4.2.1/lib/external/intel/mpifort/lib

So I have only to tell yambo where to look to the libxc.a in order to link it properly....
and by the way...how should I do???

many thanks once more!

So something strange happened during the compilation,
try to move the libs in the dir when yambo looks for them and see if it works.

It the this

Code: Select all

/lib64

in the installation path of the external libraries that creates conflicts with the standard yambo installation procedure.
I should get rid of this.
