Hi Carlos,
I just tried building with
../configure --enable-openmp --with-application
with gcc 4.2.3 and it worked fine. I think the reason you are having
trouble is because of the addition of --with-lp=yes, which should not be
needed and may in fact mess things up. Can you try without that option
and see if it works?
Cheers,
Ted
