Thanks Daniel but the issue is not moving the links. The issue is that
we build static binaries on the supercomputer so no *.so libraries are
available. The tests at configure time are happy with *.a but at run
time, according to strace, mmap is searching for libmpich.so. It is
happy with libblas.a, liblapack.a etc. but it is sure it wants
libmpich.so even though it linked libmpich.a. So, I am stumped.

Hi folks,
I am new here. I am trying to compile Siesta 2.0 with MPI on a LINUX
PowerPC and MPICH-1.2.7. It configures and runs its tests against
libmpich.a and builds. I have added --disable-shared to my configure
script. Everything looks fine until runtime. I then get the error:
siesta-2.0/Src/siesta: error while loading shared libraries:
libmpich.so: cannot open shared object file: No such file or directory
this message is copied three times. I have tried lots of wild ideas and
searched through your message archives. Please, someone tell me how to
turn it off! Thanks very much!
My guess would be, although I can't be certain, that all you have to do
is had the folder where you have libmpich.so to your LD_LIBRARY_PATH.
Supposing your folder containing that library is /opt/mpich/lib you
should do:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/mpich/lib
Linux has some places where it automatically looks for libraries but, if
you don't put your stuff there you have to declare it.
Best,
