Refocus
This is the ASCII version of the installation instructions, that was
automatically generated from the DocBook source. The doc.html and doc.pdf
versions of these instructions in the doc directory are more readable.
_________________________________________________________________
Installation
Requirements
For installing refocus you need the following:
* The Gimp, of course. This plug-in should work with versions > 1.2.
* Gtk+-2 plus pkg-config.
* Optional: ATLAS, see Using ATLAS
Installation should be simple. Untar the distribution. If you want to
use ATLAS install it in lib-atlas (see Using ATLAS).
Then run ./configure in the top-level directory.
Then run make install-bin if you want to install the plug-in under
your home directory or make install-admin-bin if you want to install
the plug-in under your Gimp's system directory.
If you have gtk-doc installed you can build the system documentation
in the gtk-doc directory. In this case you must invoke configure with
the --enable-gtk-doc option. When you make it for the first time make
will fail with the message No rule to make target `tmpl/*.sgml'.
Running make again will fix this problem.
_________________________________________________________________
Using ATLAS
What is ATLAS
ATLAS (see http://math-atlas.sourceforge.net) is a system for generating
high-performance mathematical libraries. It generates a library that is
specifically tuned to your processor and compiler. refocus needs some
routines for solving a linear system of equations. By default refocus uses
an unoptimized version from the CLAPACK distribution (see
http://www.netlib.org/clapack).
_________________________________________________________________
How to use ATLAS
* Make ATLAS generate its libraries. For instructions see the ATLAS
documentation. Depending on your system, this may take a long
time. During the installation you have to select a name to
identify your configuration. In the following examples we will use
Linux_PII as the chosen name.
* Go to the subdirectory lib/Linux_PII and run make.
cd lib/Linux_PII
make
This will generate a gzipped tar file that contains the generated
libraries and include files.
* Copy the gzipped tar file to the refocus directory and unpack it.
cp ~/ATLAS/lib/atlas3.4.1_Linux_PII.tgz ~/refocus
cd ~/refocus
zcat atlas3.4.1_Linux_PII.tgz |tar xvf -
mv Linux_PII lib-atlas
* If you have already run configure , you must delete the file
config.cache.
* Then run configure. If everything is OK you should see a message
like using atlas in lib-atlas/lib.
* Now run make.
