Spud build fails with OpenMPI compilers

[Tim Greaves]

When built on a system running Ubuntu LTS 12.04 with system OpenMPI, the following set of commands:

bzr co lp:spud
cd spud
CC=mpicc FC=mpif90 CXX=mpicxx ./configure
make

fails with:

libtool: link: mpif90 -shared -fPIC .libs/spud.o .libs/spud_interfaces.o .libs/tinystr.o .libs/tinyxml.o .libs/tinyxmlerror.o .libs/tinyxmlparser.o .libs/fspud.o -Wl,-rpath -Wl,/usr/lib/openmpi/lib -Wl,-rpath -Wl,/usr/lib/openmpi/lib -lstdc++ -L/usr/lib/openmpi/lib -L/usr/lib/gcc/x86_64-linux-gnu/4.6 -L/usr/lib/gcc/x86_64-linux-gnu/4.6/../../../x86_64-linux-gnu -L/usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../lib -L/lib/x86_64-linux-gnu -L/lib/../lib -L/usr/lib/x86_64-linux-gnu -L/usr/lib/../lib -L/usr/lib/gcc/x86_64-linux-gnu/4.6/../../.. -l /usr/lib/openmpi/lib/libmpi_f90.so /usr/lib/openmpi/lib/libmpi_f77.so /usr/lib/openmpi/lib/libmpi.so /usr/lib/openmpi/lib/libopen-rte.so /usr/lib/openmpi/lib/libopen-pal.so -lnsl -lutil -ldl -lgfortran -lquadmath -lm -lpthread -lc -lgcc_s -O3 -pthread -Wl,-soname -Wl,libspud.so.0 -o .libs/libspud.so.0.0.0

I.e. looks to be either putting an empty -l , or failing to entirely remove a -l<something>.

This is reproduceable on a redhat system and looks to be a reasonably general failure.

This appears to be linked to the use of -rpath in the Makefile.in at line 58:

./libtool --mode=link --tag=FC $(FC) $(FCFLAGS) -o $(LIB) $(OBJS) $(LIBS) -rpath @prefix@/lib

Without the -rpath specified, the build completes fine.
