PREREQUISITES


Consider reading platform specific requirements listed below.

Linux

  • CMake >= 3.x
  • Git >= 1.7.10
  • Svn >= 1.7
  • Qt 4.8.6. See details here. See some history here (Note that any version >= Qt 4.7.4 can be used only for Ubuntu < 12.04)

Debian

  • Debian squeeze/wheezy/testing(jessie) users, start by pasting the following lines in a terminal
sudo apt-get install subversion git-core git-svn
sudo apt-get install make gcc g++ libx11-dev libxt-dev libgl1-mesa-dev libosmesa6-dev libglu1-mesa-dev libfontconfig-dev libxrender-dev libncurses5-dev
sudo apt-get install cmake
sudo apt-get install qt-sdk

Ubuntu

  • Ubuntu users, start by pasting the following lines in a terminal
sudo apt-get install subversion git-core git-svn
sudo apt-get install make gcc g++ libx11-dev libxt-dev libgl1-mesa-dev libglu1-mesa-dev libfontconfig-dev libxrender-dev libncurses5-dev


For Ubuntu < 12.04: 

sudo apt-get install cmake # Only for Ubuntu < 12.04

For Ubuntu < 14.04.3: 

sudo apt-get install libosmesa6-dev
  • NOTE: on Ubuntu 14.04.3 LTS, attempting to install libosmesa6-dev results in an error:
The following packages have unmet dependencies:
 libosmesa6-dev : Depends: libosmesa6 (= 10.1.3-0ubuntu0.4) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

See Bug 1424059.

Slicer compiles successfully without that package, but VTK_OPENGL_HAS_OSMESA is disabled.

For Ubuntu 12.04 and above: You *MUST download the standard CMake binary* from http://cmake.org/download because the distributed version of CMake cannot be used to build slicer. For example, on a 64-bit system, you will download the file cmake-X.Y.Z-Linux-x86_64.tar.gz associated with the latest stable version.

References:


For Ubuntu 12.04, 12.10, 13.04 and 13.10: Qt 4 >= 4.8.5 MUST be used. See reference below for more details.

CentOS

  • CentOS user type:
yum install make gcc-c++ libX11-devel libXt-devel libXrender-devel libXext-devel libGLU-devel mesa-libOSMesa-devel mesa-libGL-devel mesa-libGLU-devel ncurses


MacOSX

MacOSX 10.9.4 (Mavericks)

(1) Make sure to install this update: http://support.apple.com/kb/DL1754

(2) Use CMake 3.0.1 - it is known to be working and is supported (if you want to use CMake already installed on your system, 2.8.12.2 is known to work on Mac OS X 10.9.5) 

$ curl -O http://www.cmake.org/files/v2.8/cmake-2.8.11-Darwin64-universal.tar.gz
$ tar -xzvf cmake-2.8.11-Darwin64-universal.tar.gz --strip-components=1

$ CMake\ 2.8-11.app/Contents/bin/cmake --version
cmake version 2.8.11
  • Git >= 1.7.10
  • Svn >= 1.7
  • XCode (for the SDK libs)
    • After installing XCode, install XCode command line developer tools:
xcode-select --install

Mac OSX 10.11 (El Capitan)

The standard Qt4 installers fail on this version and the 4.8.6 source code won't build. But as described on the slicer-devel mailing list it is possible to install the homebrew version of qt4.

After installing the OS and Xcode, run the following two commands: 

brew install qt4
xcode-select --install

TCL does not build correctly on El Capitan as of 2015-12-03, so when building Slicer turn Slicer_USE_PYTHONQT_WITH_TCL off.

Windows

Common Prerequisites

  • CMake >= 3.0
  • Git >= 1.7.10
    • Note For convenience, you could update the PATH variable so that git can be automatically discovered when configuring Slicer. If not, you will have to specify the GIT_EXECUTABLE at configure time.
  • SlikSvn . If using TortoiseSVN (versions that support command line tools), make sure you install Command line tools (disabled by default)
  • NSIS (optional): Needed if packaging Slicer - Click here to download.
  • Qt 4.8.7. See details here.

Tested and recommended build environment

  • Visual Studio 2013 with Update 5, as of commit 7160260: Slicer compilation is successful, with some caveats.
    • CMake >= 3.3.1
    • Build Qt 4.8.7 with SSL support using qt-easy-build.
    • For Debug mode, disable Slicer_USE_SimpleITK in CMake.
