Hmm; that's odd.
Is icc / icpc able to find libnuma with no -L, but ifort is unable to
find it without a -L?

In my final link with mpif90 I get the error:
/usr/bin/ld: cannot find -lnuma
Adding --showme reveals that
-I/home/terry/bin/Local/include -pthread -I/home/terry/bin/Local/lib
is added to the compile early in the aggregated ifort command, and
-L/home/terry/bin/Local/lib -lmpi_f90 -lmpi_f77 -lmpi -lopen-rte
-lopen-pal -lpbs -lnuma -ldl -Wl,--export-dynamic -lnsl -lutil -lm -
ldl
is added to the end.
I note than when compiling Open MPI -lnuma was visible in the gcc
arguments, with no added -L.
On this system libnuma.so exists in /usr/lib64. My (somewhat long!)
configure command was
./configure --enable-static --disable-shared
--prefix=/home/terry/bin/Local --enable-picky --disable-heterogeneous
--without-slurm --without-alps --without-xgrid --without-sge
--without-loadleveler --without-lsf F77=ifort
Should mpif90 have bundled a -L/usr/lib64 in there somewhere?
