[CP2K:8895] I cannot understand why it does not compile against XSMM

[Ari Paavo Seitsonen]

Dear Davide,

  In the recent versions of libXSMM one needs two libraries:

#> nm
/sw/target/intel/lib/libxsmm/libxsmm-20160831_gcc-5.4.0/lib/libxsmmf.a |
grep -i dmmav
#> 0000000000002500 T __libxsmm_MOD_libxsmm_dmmavailable

Please try adding
/ichec/home/users/davide/lib/libxsmm.git/tags/1.6/lib/libxsmmf.a in your
arch file; I have these two libraries (also as static, with explicit path
to the lib*.a files) as

             ...
             $(LIBXSMM_PATH)/lib/libxsmm.a \
             $(LIBXSMM_PATH)/lib/libxsmmf.a \
             ...

    Greetings from Paris,

       apsi
