Back in the days when I worked on heterogeneous machines like this, I had logic in my shell startup files to set paths properly. E.g. (pseudocode):
----- arch=`config.guess` switch $arch: case *x86_64-linux*) prefix_path=$HOME/x86_64-linux-stuff/bin prefix_ldpath=$HOME/x86_64-linux-stuff/lib prefix_manpath=$HOME/x86_64-linux-stuff/share/man ;; case *sparc*) prefix_path=$HOME/sparc/bin prefix_ldpath=$HOME/sparc/lib prefix_manpath=$HOME/sparc/share/man ;; ...etc. export PATH=$prefix_path:$PATH export LD_LIBRARY_PATH=$prefix_ldpath:$LD_LIBRARY_PATH export MANPAHE=$prefix_manpath:$MANPATH ----- > On Apr 17, 2015, at 5:34 AM, Ralph Castain <r...@open-mpi.org> wrote: > > Hi Gilles > > What launch environment?
