[Trilinos-Users] MOOCHO installation

[John Pye]

Hi Roscoe,

Given the difficulty in getting a full Trilinos built, I wonder if you
could give me some pointers on how to get a minimal MOOCHO system
running. In ASCEND, we have our own linear algebra routines (MTX). I
believe you may be familiar with it. I saw in the documentation that
external linear routines are supported but deprecated. Should I attempt
to connect MOOCHO to our linear solver, or should I use the Thyra thing
as you recommended in the documentation?

Regarding the installation issues, I have been working on an RPM for
trilinos. Only non-MPIA version at present, and only static libraries
AFAICT. Given that it contains only static libraries, this package can
easily be installed on Linux systems in order to satisfy build-time
dependencies but doesn't need to be there at run-time. So the presence
of lots of header files isn't really a concern. It could make building
software with trilinos dependencies *much* simpler for Linux users, in
any case.

The ideal situation with the header-files, however, would be for them to
by default install to /usr/include/trilinos, with shared libraries
(and/or static libraries) installed in /usr/lib. I'd refer you to the
way that the Boost libraries do it. They always #include
<trilinos/whatever/whatever.h> instead of #include
"whatever/whatever.h", which means that all the header files live nicely
in a directory of their own within /usr/include.

If I enable python, I'll perhaps get shared libraries, but are they
C/C++ shared libraries for the basic Trilinos code, or are they
libraries containing primarily the Python bindings?

Cheers
JP
