[MOAB-dev] "Obj_unknown" when building mbzoltan

[de Almeida, Valmor F.]

For the record here is a description of the MBZoltan compilation issue
and a work around.

The current MBZoltan tool install requires a compiled Zoltan
distribution tree somewhere in the system. This is not necessary and not
intended. The sufficient and necessary installation of Zoltan is what I
described in an earlier e-mail. I have confirmed this with Karen Devine.

Therefore an option like  --with-zoltan-arch=OS  in the MOAB install
should not exist. The option --with-zoltan=DIR is sufficient.

The MBZoltan install design was mimicked after the examples in the
Zoltan distribution which do require a full Zoltan tree because of a bug
which will be fixed in the next release 3.1.

To circumvent the problem let the MOAB script stop with an error and
repeat the last command to build MBZoltan but with the correct path (on
my system)

-L/usr/local/zoltan/lib -lzoltan


In the future a simpler MBZoltan install should be considered based on a
minimal Zoltan install.
