compilation error!

see the error msg:
configure: error: unrecognized option: `--wth-fft-libs=-mkl'

--with-fft-libs="-mkl"

Ohh sorry, missing I.
It is going now then I hit make yambo. we will see

if FFTW were correctly found by yambo this should not happen...
did you do a make clean_all before reconfiguring and re-compiling ?

check your config.log (and config/report and config/setup) to see whether FFTW have been recognised or not..
If Goedecker FFTs (sgfft) have been found instead (as a default) it means FFTW have not been recognized
Do you have mil libs in your path ?

Yes I did make clean_all.
but where to find config/report and config/setup?
how to check this: Do you have mil libs in your path ?
I am attaching the .log file that appear in the home dir of yambo.

It says files is too big!

[andrea.ferretti]

the files I mnention before are

yambo/config/setup
yambo/config/report

where yambo is the release main directory.
Is config.log too large ? (strange)

see the attached files;

Hi Jarek,

your intel compiler is very old (ifort (IFORT) 10.1 20080602), and this is probably the reason why -mkl
is not a recognised option.
now:

* since we are fort 16.x, I strongly recommend to upgrade your intel compiler (a number of problems we see
now could be miscompilations)
* if you want to link FFTW, either you use those from MKL (though you need to check what are the proper
linking flags of your version)
* otherwise you can install fftw3 if you haven't them already on your computer (it is not too difficult to do)
and link them directly
--with-fft-libs="-L/dir-where-fftw-is -lfftw3 " or similar

hope it helps
Andrea

Thank you Andrea. I need to talk with my adviser coz he is the admin.
