Having just downloaded and installed Open MPI 1.3 with ifort and gcc, I merrily went off to compile my application.
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?
