[DFTB-Plus-User] Compilation error

[Ben Hourahine]

Hello Hannah,

the problem is due to a missing LAPACK library. The default ifort option
file in the snapshot is expecting to find the intel MKL library
(which includes the functionality of lapack) in /usr/local/lib but your
system is different in some way. If you have MKL installed elsewhere add

MKL_LIBDIR = genuine location

to Makefile.user at the end. Otherwise if you have a different
LAPACK/BLAS set up, look at examples in sysmakes/make.i686-linux-*

Cheers

Ben
