ohl@thopad:~mc$ zcat omega-yyyy-mm-dd-hhmm.tar.gz | tar xf -
will unpack the sources to the directory omega. The
subdirectories of omega are
bin
contains executable instances of O'Mega: f90_SM.bin
(f90_SM.opt if the sytem is supported by O'Caml's native
code compiler), f90_QED.bin, etc.
doc
contains LATEX sources of user documentation.
examples
contains currently no supported examples.
lib
contains library support for targets (Fortran90/95 modules, etc.).
src
contains the unabridged and uncensored sources of O'Mega,
including comments.
tests
contains a battery of regression tests. Most tests
require Madgraph [8].
web
contains the `woven' sources, i. e. a pretty printed
version of the source including LATEX documentation. Weaving
the sources requires programs, ocamlweb and noweb.
A complete PostScript file is available from the same place as
the O'Mega sources. (It is not required for the end user to read this.)
You need version 3.01 or higher4. You can get it
from http://pauillac.inria.fr/ocaml/. There are precompiled
binaries for some popular systems and complete sources. Building from
source is straightforward (just follow the instructions in the
file INSTALL in the toplevel directory, the defaults are almost
always sufficient) and takes O(10) minutes on a modern
desktop system. If available for your system (cf. the file
README in the toplevel directory), you should build the native
code compiler.
This should be available for any system of practical importance and it
makes no sense to waste physicist's time on supporting all
incompatible flavors of make in existence. GNU make is
the default on Linux systems and is often available as gmake on
commercial Unices.
Not required for compiling or running O'Mega, but Fortran90/95 is
currently the only fully supported target.
O'Mega is known to be compiled correctly with recent versions of the
Intel Fortran compiler (at least version 7.0, earlier versions do
not work), the Lahey/Fujitsu Fortran95 compiler and the NAG
Fortran95 compiler. The Intel compiler is available free of charge
for non-commercial purposes. [NB: Support for the `F' Fortran90/95
subset compiler by Imagine1 and NAG has been dropped.]
Before the next step, O'Caml must have been installed. Configuration
is performed automatically by testing some system features with the
command
$ ./configure
See
$ ./configure --help
for additional options. NB: The use of the options
--enable-gui and --enable-unsupported is strongly
discouraged. The resulting programs require additional prerequisites
and even if you can get them to compile, the results are unpredictable
and we will not answer any questions about them. NB: configure
keeps it's state in config.cache. If you want to reconfigure
after adding new libraries to your system, you should remove
config.cache before running configure.
