Hi Davide,

ctrig.o is part of the FFT library within CP2K.  It should be compiled from the source file cp2k/src/fft_lib/ctrig.F - you should first check you have this file.  ctrig.o should get built automatically by the Makefile, so sounds like something went wrong in your build process.  Probably best is to start again:

make ARCH=Linux-x86-64-gfortran VERSION=psmp realclean

Hopefully this should fix the issue.  I have recently built CP2K with for this arch and it worked fine for me.
