+
== Install Distribution-specific binary Package ==
−
Installing PyMol is very simple, even from source.  On Linux, you need the following requirements:
 
−
* [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
 
  
−
== Generic Linux ==
+
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.
  
−
=== From Source ===
+
Command line install examples for some popular distributions:
−
Many people want the latest versions of PyMOL as they usually have valuable features, but don't want to build PyMOL.  Building PyMOL is generally '''very''' simple. 
 
−
 
 
−
This quick install assumes you already have a [http://subversion.tigris.org/ Subversion] client installed, have internet access, and all the dependencies are satisfied.
 
−
 
 
−
To obtain a copy of the current revision version issue the command:
 
  
 
<source lang="bash">
 
<source lang="bash">
−
svn co https://pymol.svn.sourceforge.net/svnroot/pymol/trunk/pymol pymol
+
# Debian/Ubuntu
−
</source>
+
sudo apt-get install pymol
  
−
Then go into the source directory:
+
# Fedora
 +
yum install pymol
  
−
<source lang="bash">
+
# Gentoo
−
cd pymol
+
emerge -av pymol
 
</source>
 
</source>
  
−
If you have root or superuser privileges you can continue with the installation. If not follow [http://pymolwiki.org/index.php/Linux_Install#Installing_without_root_Privileges this guide]
+
== Install from Source ==
  
−
Run the first stage of the installation:
+
Installation from source gives you the latest version and is the generic way to install PyMOL.

<source lang="bash">
+
=== Requirements ===
−
python setup.py install
 
−
</source>
 
  
−
Run the second stage of the installation:
+
Libraries as well as development files (headers) of the following software is
−
<source lang="bash">
+
required:
−
python setup2.py install
 
−
</source>
 
  
−
A launch script '''pymol''' will have been created. You can copy this script in the /usr/local/bin directory, so that any user of the system can use PyMOL:
+
* [http://www.python.org/ Python] (with distutils)
−
 
+
* [http://pmw.sf.net Pmw] (Python Megawidgets)
−
<source lang="bash">
+
* OpenGL driver (I use [http://www.nvidia.com/object/unix.html NVidia])
−
cp ./pymol /usr/local/bin
+
* libpng
−
</source>
+
* freetype
−
 
 
−
Test your installation. 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>
 
  
−
If you want to update the source code to the latest svn revision, go into the pymol directory and issue the command:
+
On many Linux systems, one of the following commands installs all requirements:
  
 
<source lang="bash">
 
<source lang="bash">
−
svn up
+
# Debian/Ubuntu/Mint11
−
</source>
+
sudo apt-get install subversion build-essential python-dev python-pmw \
 +
  libglew-dev freeglut3-dev libpng-dev libfreetype6-dev
  
−
To uninstall the PyMOL:
+
# Fedora
 +
yum install subversion python-devel freeglut-devel freetype-devel tkinter python-pmw
  
−
<source lang="bash">
+
# Gentoo
−
python setup2.py uninstall
+
emerge -av dev-vcs/subversion dev-lang/python dev-python/pmw media-libs/glew \
 +
  media-libs/freeglut media-libs/libpng media-libs/freetype
 
</source>
 
</source>

==== Installing without root Privileges ====
+
=== Get latest Source from SVN ===
  
−
Use the prefix command to specify where to install PyMOL:
+
This will download the latest source to '''/tmp/pymol''':
  
 
<source lang="bash">
 
<source lang="bash">
−
python setup.py install --prefix /dir_to/pymol/py_build
+
cd /tmp
−
</source>
+
svn co https://pymol.svn.sourceforge.net/svnroot/pymol/trunk/pymol pymol
−
 
+
cd pymol
−
Then, you'll need to modify your '''PYTHONPATH''' variable:
 
−
 
 
−
<source lang="bash">
 
−
export PYTHONPATH=$PYTHONPATH:/dir_to/pymol/py_build/lib/python{version}/site-packages
 
 
</source>
 
</source>
  
−
Install to prefix:
+
=== Compile and install ===
  
−
<source lang="bash">
+
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'''.
−
python setup2.py install --prefix /dir_to/pymol/py_build
 
−
</source>
 
−
 
 
−
Now you can run PyMOL:
 
  
 
<source lang="bash">
 
<source lang="bash">
−
./pymol
+
#!/bin/bash -e
−
</source>
 
  
−
=== Compiling By Hand ===
+
prefix=/opt/pymol-svn
−
Due to the large variance of Linux systems, some systems may work fine with PyMol, and some may have related install issues.  To overcome this, you can download the '''ext''' package and the PyMol source and compile/install by hand.  The '''ext''' package is available from the Source Forge download section and contains all the necessary software to make PyMol run.  In the most recent available version (0.99rc1) this includes

====Supported Packages====
+
python setup.py build install \
−
The above packages don't need to be installed from their source-packages only.  That is, you can use your system's installer (eg. yum, YaST, apt-get, rpm, etc.) to install the packages.  '''Just be sure, if you install the above packages with your system's installer, that you also include the development packages.  PyMOL needs the source/header files to compile against.  For example, don't only install, ''freeglut-2.4.0'' but also look for, and install, ''freeglut-2.4.-devel'' '''.

 +
    --install-purelib=$modules \

    --install-platlib=$modules
  
−
Once downloaded, see the file '''pymol/INSTALL''' and '''pymol/INSTALL.generic'''.
+
export PYTHONPATH=$modules:$PYTHONPATH
−
 
+
python setup2.py install
−
Here's the basic steps to install by source:
+
install pymol $prefix/
−
# get the source [http://delsci.com/rel/0_98/#OtherUnix PyMol Source]
 
−
# extract both packages, rename ext-VERSION.tgz to ext and move it into the pymol directory
 
−
# cd pymol
 
−
# cd ext
 
−
# vi build.com  # edit the build file
 
−
# cd ..
 
−
# cp setup/Rules.make . # or correct Rules.make file for your machine
 
−
# vi Rules.make        # make appropriate changes
 
−
# vi setup.py          # make appropriate changes
 
−
# make
 
−
 
 
−
Warnings:
 
−
* if you're using a 64-bit machine, lib becomes lib64 for almost everything
 
−
* ensure you have the correct Python path and version (is it 2.3?  2.4?)
 
−
* make sure you make the changes in '''Rules.make''', '''setup.py''', and '''Makefile''', for your platform. For x86_64, besides above files, change following line in contrib/modules/Makefile.pre.in.src pointing to lib64 ([[leafyoung at yahoo dot com]])
 
−
  LIBP = $(exec_installdir)/lib'''''64'''''/python$(VERSION)
 
−
 
 
−
Copy the appropriate setup/Rules.XXX file to the base PyMol dir.  You'll have to edit the file for your system.  Then run 'make'.

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
sudo apt-get install pymol

# Fedora
yum install pymol

# Gentoo
emerge -av 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:

  • 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/Mint11
sudo apt-get install subversion build-essential python-dev python-pmw \
  libglew-dev freeglut3-dev libpng-dev libfreetype6-dev

# Fedora
yum install subversion python-devel freeglut-devel freetype-devel tkinter python-pmw

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

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

Problems

  • gcc-4.5 is broken for pymol install, use gcc-4.4 (Mint11 Linux, PyMOL 1.4.1, reported by User:Tlinnet)
  • 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.
