Continue the reorganization of the configure system. Move files from the main config directory to their appropriate level-specific config directories. Modify the configure system to correctly handle compiler detection, test, and setup so that all things pertaining to opal and orte are done at the lower level, with the ompi configure system only looking at mpi-specific options. Ensure the wrapper compilers for orte and ompi only get built when appropriate. Add support for c++ to the orte wrapper compilers, both script and non-script versions. This commit was SVN r22138.

# Special case for OFED/Linux: the default /etc/dat.conf that
|
|
# ships with OFED is broken in that it includes DAT providers that
|
|
# are not guarnateed to work (e.g., it includes providers for ib0,
|
|
# ib1, ib2, ib3, and bond0). Usually, a sysadmin will need to
|
|
# edit this file to configure it for the specific environment in
|
|
# which it will be used. Hence, if you run the udapl BTL on
|
|
# Linux/OFED, you'll get a bunch of warning messages about the
|
|
# providers that don't work. However, on Linux/OFED, you don't
|
|
# really want to use udapl anyway; you likely really want to use
|
|
# the openib BTL (i.e., native verbs, not udapl).
|
|
|
|
# So after exploring many different scenarios, the least evil
|
|
# solution seemed to be to disable building the udapl BTL on
|
|
# Linux/OFED *unless the user specifically asks for it.* To be
|
|
# specific: on Linux/OFED, if you do not specify
|
|
# --with-udapl(=DIR), the udapl BTL will not be built.
