This means you must recompile LAM/MPI with the -fPIC option. There
are two ways to do that. The simplest is to recompile LAM/MPI with
the options --enable-shared --disable-static. This will also
probably make it easier to use R with LAM/MPI, but you will have to
use LD_LIBRARY_PATH or rpath to make sure the LAM/MPI shared
libraries can be loaded.
The other option is to still compile LAM/MPI as a static library and
compile with the -fPIC option. This can be done by using a configure
line like:
./configure CFLAGS="-fPIC" CXXFLAGS="-fPIC" FFLAGS="-fPIC" <normal
options>
Hope this helps,
Brian
