[QE-users] Error with libmbd QE-7.3.1

[Paolo Giannozzi]

CMake or autoconf? in the latter case: first of all verify that 
Modules/mbdlib.o has been correctly compiled. If it has, try the command 
that fails and do something (reshuffle the order of libraries, add the 
library again, ...) until it works: some linkers are pickier than 
others. If nothing works and you do not need many-body dispersions, add 
-D__NOMBD to MANUAL_DFLAGS, delete Modules/mbdlib.o, recompile
