[DFTB-Plus-User] error while compiling dftb+

[Bálint Aradi]

Dear Bedamani,

The makefile for x86_64-linux-gfortran is set up to use the ATLAS
library as BLAS/LAPACK replacement as this should be considerably faster
than the legacy versions. However, by setting

LIB_BLAS = -lblas

in makefile.x86_64-linux-gfortran, you can advice the make system to
look for the libblas.a instead of the various ATLAS components.

Best regards,

  Bálint
