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:

# 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'

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:

  • Subversion to download the source code
  • Python (with distutils)
  • Pmw (Python Megawidgets)
  • OpenGL driver (I use NVidia)
  • libpng
  • freetype

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

# 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

Get latest source from SVN

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

cd /tmp
svn co https://pymol.svn.sourceforge.net/svnroot/pymol/trunk/pymol pymol
cd pymol

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 prefix variable to something like $HOME/pymol-svn.

#!/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/

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

/opt/pymol-svn/pymol

Troubleshooting

  • 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)
sudo apt-get install build-essential gcc-4.4 g++-4.4
export CC=/usr/bin/gcc-4.4
  • If you get an error message "ImportError: No module named Pmw" and lack half of the user interface, then run the additional command
python setup2.py install pmw

to install a copy of the Python MegaWidgets.

Mint 12 compile and install with MPEG support

Make a text file "installpymol.sh" and make it executable

chmod u+x installpymol.sh

Put this in the file, modify the first line

#!/bin/bash -e
pymoldir=/home/YOU/Software/pymol
modules=$pymoldir/modules
svnpymol=svnpymol
svnfreemol=svnfreemol
pymolplugins=pymolplugins

chmod u+x $pymoldir/pymolMPEG.sh 
 
## Make a link, so we execute pymol with the freemol env exported
sudo ln -s $pymoldir/pymolMPEG.sh /usr/bin/pymol

t="'"
echo "import sys" >> ~/.pymolrc.py
echo "sys.path.append($t$pymoldir$t)" >> ~/.pymolrc.py
echo "import $pymolplugins" >> ~/.pymolrc.py

Update script

To pull and update PyMOL, one can make this script

Make a text file "updatepymol.sh" and make it executable

chmod u+x updatepymol.sh

Put this in the file, modify the first 3 lines

#!/bin/bash -e
pymolsvn=/home/tlinnet/Software/pymol/svnpymol
pymoldir=/home/tlinnet/Software/pymol
freemolsvn=/home/tlinnet/Software/pymol/svnfreemol
 
# gcc 4.5 broken for install in ubuntu
export CC=/usr/bin/gcc-4.4
 
svn up $pymolsvn
svn up $freemolsvn
 
modules=$pymoldir/modules
cd $pymolsvn
python setup.py build
sudo python setup.py install
sudo python setup.py install --home=$pymoldir --install-purelib=$modules --install-platlib=$modules
export PYTHONPATH=$modules:$PYTHONPATH
sudo python setup2.py install
install $pymolsvn/pymol $pymoldir/
 
########## Setup freemol - for MPEG support ############
cd $freemolsvn/src/mpeg_encode
export FREEMOL=$freemolsvn/freemol
./configure
make
make install

Change MPEG settings

Change settings in

/home/tlinnet/Software/pymol/svnfreemol/freemol/libpy/freemol/mpeg_encode.py

For example, change in line 205:
FRAME_RATE 24
(Not, only legal values is allowed: 23.976, 24, 25, 29.97, 30, 50 ,59.94, 60)

Then restart PyMOL.
