Undefined reference to 'ddot_' issue

Hi.

Recently I compiled the qe-6.6-ReleasePack in freshly installed Ubuntu 18.04 with standard prerequisites available in user_guide.

After I compiled with:

./configure

make all

then I got this:

Xlib/libqela.a ../../UtilXlib/libutil.a ../../dft-d3/libdftd3qe.a /home/dika/q-e-develop//clib/clib.a  /home/dika/q-e-develop//iotk/src/libiotk.a   /home/dika/q-e-develop//LAPACK/liblapack.a -L/home/dika/q-e-develop//FoX/lib  -lFoX_dom -lFoX_sax -lFoX_wxml -lFoX_common -lFoX_utils -lFoX_fsys   /home/dika/q-e-develop//LAPACK/libblas.a  /home/dika/q-e-develop//LIBBEEF/libbeef.a

Is there something wrong with my compilation arguments?

Thank you.
