Installation Linux

This section describes how to install ITK with python wrappings on Fedora 19 or 20, or Ubuntu 14. This can of course be extended to other Linuxes.

Step 1: Dependencies

Fedora 20 has very few packages installed y default, so you may have to install them manually.

On Fedora 20:

  • yum install gcc
  • yum install python-devel
  • yum install vxl

Python will need to be installed along with the Python development headers (Python.h), which is not the case on most platforms:

  • Install the python-devel package.

Step 2: Setup the build

Clone the git repository in /home/yourname/ITK:

  • cd
  • git clone git://
  • git checkout tags/v4.5.2 # Optional, if you want to use a stable version

Create a build directory, it is recommended to build outside of the source directory:

  • mkdir build
  • cd build

Use cmake to configure your build

  • ccmake ../ITK -DITK_WRAP_PYTHON=ON

Set different variables, you may have to configure [C] the build 2 or 3 times. Use the advanced mode [T] to see all the possibilities.

  • PYTHON_EXECUTABLE = /usr/bin/python
  • USE_SYSTEM_SWIG=OFF # Will use ITK's swig (recommended)

On Fedora 19 or 20:

  • PYTHON_INCLUDE_DIR = /usr/include/python2.7
  • PYTHON_LIBRARY = /usr/lib64/
  • PY_SITE_PACKAGES_PATH = /usr/lib64/python2.7/site-packages

On Ubuntu 14:

  • PYTHON_INCLUDE_DIR = /usr/include/x86_64-linux-gnu/python2.7
  • PYTHON_LIBRARY = /usr/lib/x86_64-linux-gnu/
  • PY_SITE_PACKAGES_PATH = /usr/lib/python2.7/dist-packages

Once configuration is finished, you may now generate the needed files by pressing [g].

Step 3: Run the build

  • make

Step 4: Install

You need to have root access to install ITK (if you left the default installation path):

On Fedora:

  • su # Type your root password
  • make install

On Ubuntu: Here, the super-user account is disabled by default, run the install step like this:

  • sudo make install # Type your root password

ITK will install by default in /usr/local/lib. Now, you have to tell the system that the files have been installed here.

  • cd /etc/
  • add a file called itk-46.conf, which should contain only one line: /usr/local/lib
  • ldconfig # tells the system to read the files in

Step 5: Test your installation

  • python
  • import itk
  • itk.Image

This should run without producing an error.
