Hi --
We will be fixing this in LAM 7.1 release. Thanks for pointing this out!

# Hello,
# While testing the new Warewulf 2.1, I discovered that the LAM 7.0.4

# rank 0, tests won't sucesfully run, but will say "PASS" anyway...
#
# Here is a snippet of output from a lamtests "make -k check", with rank 0
# having a full linux install, and rank 1 having a stripped down linux,
# which is missing by accident a dynamic C++ library:
#
# mpirun -x TEST -s h C -ssi rpi usysv
# /home/users/tmattox/lamtests-7.0.4/info/./00_create_cxx
# /home/users/tmattox/lamtests-7.0.4/info/./00_create_cxx: error while
# loading shared libraries: libstdc++-libc6.2-2.so.3: cannot open shared
# object file: No such file or directory
# -----------------------------------------------------------------------------
# It seems that [at least] one of the processes that was started with
# mpirun did not invoke MPI_INIT before quitting (it is possible that
# more than one process did not invoke MPI_INIT -- mpirun was only
# notified of the first one, which was on node n0).
#
# mpirun can *only* be used with MPI programs (i.e., programs that
# invoke MPI_INIT and MPI_FINALIZE). You can use the "lamexec" program
# to run non-MPI programs over the lambooted nodes.
# -----------------------------------------------------------------------------
# PASS: 00_create_cxx
#
# Hopefully it won't be very hard to check for this failure mode.
# Unfortunatly, I'm too busy at the moment to find a solution myself (other
# than to install the missing library on my nodes ;-)
