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://itk.org/ITK.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.

• ITK_WRAP_PYTHON = ON
• BUILD_SHARED_LIBS = ON
• 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/libpython2.7.so.1.0
• 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/libpython2.7.so.1.0
• 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/ld.so.conf.d/
• 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 ld.so.conf.d

Step 5: Test your installation

• python
• import itk
• itk.Image

This should run without producing an error.
