In fact I forgot to put back to '-fast -C' the FCFLAGS variable (from
'-O3 -C'). There is still an error (many opal_*_* subroutines not found
during the ipo step) at the same place, coming from the fact that
"ld: attempted static link of dynamic object
although I put --enable-static in the configure step...
Any idea of how to make the static libraries ?
