Linux Install

Masataka: /* Requirements */

This page describes how to install open-source PyMOL on Linux.

== Install distribution specific binary package ==

Many Linux distributions provide binary packages for open-source PyMOL. They often do not provide the latest version, but if the provided package fits your needs this is the most convenient way to install PyMOL.

Command line install examples for some popular distributions:

<source lang="bash">
# Debian/Ubuntu/Mint
sudo apt-get install pymol

# Fedora
su -c 'yum install pymol'

# Gentoo
su -c 'emerge -av pymol'

# openSUSE (12.1 and later)
sudo zypper install pymol

# CentOS with EPEL
rpm -i http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm
su -c 'yum --enablerepo=epel install pymol'
</source>

== Install from source ==

Installation from source gives you the latest version and is the generic way to install PyMOL.

=== Requirements ===

Libraries as well as development files (headers) of the following software is
required:

* [http://subversion.apache.org/ Subversion] to download the source code
* [http://www.python.org/ Python] (with distutils)
* [http://pmw.sf.net Pmw] (Python Megawidgets)
* OpenGL driver (I use [http://www.nvidia.com/object/unix.html NVidia])
* libpng
* freetype

On many Linux systems, one of the following commands installs all requirements:

<source lang="bash">
# Debian/Ubuntu/Mint
sudo apt-get install subversion build-essential python-dev python-pmw \
libglew-dev freeglut3-dev libpng-dev libfreetype6-dev

# Fedora/CentOS
su -c 'yum install subversion python-devel freeglut-devel freetype-devel tkinter python-pmw'

# Gentoo
sudo -c 'emerge -av dev-vcs/subversion dev-lang/python dev-python/pmw media-libs/glew \
media-libs/freeglut media-libs/libpng media-libs/freetype'

# openSUSE
sudo zypper install python-devel freeglut-devel gcc-c++ glew-devel libpng-devel python-pmw subversion
</source>

=== Get latest source from SVN ===

This will download the latest source to '''/tmp/pymol''':

<source lang="bash">
cd /tmp
svn co https://pymol.svn.sourceforge.net/svnroot/pymol/trunk/pymol pymol
cd pymol
</source>

=== Compile and install ===

This will install PyMOL as normal user into '''/opt/pymol-svn'''. If you don't have write permissions to '''/opt''', change the <code>prefix</code> variable to something like '''$HOME/pymol-svn'''.

<source lang="bash">
#!/bin/bash -e

prefix=/opt/pymol-svn
modules=$prefix/modules

python setup.py build install \
--home=$prefix \
--install-purelib=$modules \
--install-platlib=$modules

export PYTHONPATH=$modules:$PYTHONPATH
python setup2.py install
install pymol $prefix/
</source>

Now launch PyMOL like this (you may copy this launcher into your '''$PATH''',
like to '''/usr/local/bin'''):

<source lang="bash">
/opt/pymol-svn/pymol
</source>

=== Problems ===

* On Linux Mint 11 there have been reports of gcc-4.5 breaking Pymol. You could use gcc-4.4 instead. (reported by [[User:Tlinnet]])
<source lang="bash">
sudo apt-get install build-essential gcc-4.4 g++-4.4
export CC=/usr/bin/gcc-4.4
</source>

* If you get an error message "ImportError: No module named Pmw" and lack half of the user interface, then run the additional command
<source lang="bash">
python setup2.py install pmw
</source>
to install a copy of the Python MegaWidgets.

== Ubuntu/Mint compile and install with MPEG support ==
Make a text file "installpymol.sh" and make it executable
<source lang="bash">
chmod u+x installpymol.sh
</source>

Put this in the file, modify the first 3 lines
<source lang="bash">
#!/bin/bash -e
pymolsvn=/home/tlinnet/Software/pymol/svnpymol
pymoldir=/home/tlinnet/Software/pymol
freemolsvn=/home/tlinnet/Software/pymol/svnfreemol

Then restart PyMOL.
