This is certainly the default for GNU Libtool-build shared libraries
(such as Open MPI). Ralf W -- is there a way to disable this?
As a sidenote, we added the "--prefix" option to mpirun to be able to
override the LD_LIBRARY_PATH on remote nodes for circumstances like
this. For example, say you build/install to /somedir, but then
distribute Open MPI and the user installs it to /otherdir. I know
almost nothing about Fluent :-(, but do you wrap the call to mpirun
in a script/executable somewhere? Such that you could hide:
mpirun --prefix /otherdir ...
This might be good enough to do what you need.
Would that work?

Hello. I'm wondering if anyone knows of a way to get OpenMPI to
compile shared libraries without hard-coding the installation
directory in them. After compiling and installing OpenMPI, the
shared libraries have the installation libraries hard-coded in
them. For instance:
$ ldd libmpi.so
liborte.so.0 => /usr/local/fluent/develop/multiport4.4/
packages/lnamd64/openmpi/openmpi-1.1.2/lib/liborte.so.0
(0x0000002a956ea000)
libnsl.so.1 => /lib64/libnsl.so.1 (0x0000002a95852000)
libutil.so.1 => /lib64/libutil.so.1 (0x0000002a95968000)
libm.so.6 => /lib64/tls/libm.so.6 (0x0000002a95a6c000)
libpthread.so.0 => /lib64/tls/libpthread.so.0
(0x0000002a95bc4000)
libc.so.6 => /lib64/tls/libc.so.6 (0x0000002a95cd8000)
libopal.so.0 => /usr/local/fluent/develop/multiport4.4/
packages/lnamd64/openmpi/openmpi-1.1.2/lib/libopal.so.0
(0x0000002a95f00000)
/lib64/ld-linux-x86-64.so.2 (0x000000552aaaa000)
libdl.so.2 => /lib64/libdl.so.2 (0x0000002a9605a000)
In the above, "/usr/local/fluent/develop/multiport4.4/packages/
lnamd64/openmpi/openmpi-1.1.2/lib" is hardcoded into libmpi.so
using --rpath when libmpi.so is compiled.
This is problematic because the installation cannot be moved after
it is installed. It is often useful to compile/install libraries
on one machine and then move the libraries to a different location
on other machines (of course, LD_LIBRARY_PATH or some means then
needs to be used to pick up libs are runtime). This relocation is
also useful when redistributing the MPI installation with an
application. The hard-coded paths prohibit this.
I've tried to modify the "--rpath" argument in libtool and opal/
libltdl/libtool, but have not gotten this to work.
Has anyone else had experience with this? (I'm building OpenMPI
1.1.2 on linux x86_64.) Thanks in advance for any potential help.
Regards,
