Hi, Thanks for your answer.
I have no LD_LIBRARY_PATH. I am not sure it should matter anyway, though: the objdump command looks at what the object file requests, not necessarily what happens at runtime as if we were using ldd. This seems to be related to the MOFED debian packages including a .la file for the stuff they install (which is against debian practice, although not exactly for the same reason: https://wiki.debian.org/ReleaseGoals/LAFileRemoval ). Specifically, I have /usr/lib/libosmcomp.la. If I delete that file, then no -L/usr/lib shows up in the relink command for libmpi; libtool just emits -losmcomp alone, which is fine. Then the subsequent -lopen-rte finds the one installed for the library being build, not the /usr one. It still does not look good that the libmpi.la file has the following: dependency_libs=' -losmcomp -libverbs /tmp/openmpi-1.10.2/orte/libopen-rte.la /tmp/openmpi-1.10.2/opal/libopen-pal.la -lnuma -ldl -lrt -lm -lutil' (here on a machine without /usr/lib/libosmcomp.la ; when the .la file exists, -loscomp is replaced by /usr/lib/libosmcomp.la). I have the impression that having -losmcomp -libverbs *after* the opal and orte .la files would be better. I don't see how to achieve this, though (just playing with ompi/Makefile.am at the moment, to no avail so far). E.
