This page is for developers
who want to work on the internals of Open MPI itself.
If you are a
general user or system administrator looking to simply download
and install Open MPI, please

After obtaining a successful Subversion
checkout, the following tools are required for developers to
compile Open MPI from its repository sources (users who download Open
MPI tarballs do not need these tools - they are
only required for developers working on the internals
of Open MPI itself):
| Open MPI Release |
M4 Versions |
Autoconf Versions |
Automake Versions |
Libtool Versions |
| v1.0 | NA | 2.58 - 2.59 | 1.7 - 1.9.6 | 1.5.16 - 1.5.22 |
| v1.1 | NA | 2.59 | 1.9.6 | 1.5.16 - 1.5.22 |
| v1.2 | NA | 2.59 | 1.9.6 | 1.5.22 - 2.1a |
| v1.3 | 1.4.11 | 2.63 | 1.10.1 | 2.2.6 - most recent |
| trunk | 1.4.11 | 2.63 | 1.10.1 | 2.2.6 - most recent |
Note that other Autotool combinations may work, but are
untested and unsupported.
Autoconf/Automake Note: If Autoconf 2.60 (and higher) is used,
Automake 1.10 (and higher) must be used.
Libtool Note: The v1.2 branch and later (including the present trunk)
require the use of the Libtool 2 so that Open MPI can
build the Fortran 90 module as a shared library. If (and only if) you intend
to not build the Fortran 90 library or your Fortran 77 and Fortran 90 compilers
have the same name (ie, gfortran), you can use Libtool 1.5.22.
Note: There was a period of time
where OMPI nightly trunk snapshot tarballs were made with a Libtool 2.0 development snapshot. This is now
deprecated; Open MPI uses official Libtool releases (no official Open
MPI releases used the Libtool 2.0 development snapshot).
Although it should probably be assumed, you'll also need a C/C++
compiler.
The HACKING file in the top-level directory of the Open MPI checkout
details how to install the tools listed above and the steps required
to build a developer checkout of Open MPI. It always contains the
most current information on how to build a developer's copy of Open
MPI.
shell$ ./configure --prefix=$HOME/openmpi-install
[...lots of output...] |
This configures Open MPI and tells it to install under
$HOME/openmpi-install.
NOTE: by default, when configuring and building
Open MPI from a Subversion checkout, all debugging code is enabled.
This results in a significant run-time performance
penalty. There are several options for building an optimzed Open MPI;
see the HACKING file for more details.
NOTE: you only need the Subversion client.
Getting the server to compile may be quite complex and require a lot
of dependencies -- the client is currently significantly easier to
compile.
NOTE: Most Linux distributions and OSX install Flex
by default (and this is sufficient). Other operating systems may
provide "lex", but this is notsufficient -- flex is required.
