- 1 PREREQUISITES
- 1.1 Linux
- 1.2 MacOSX
- 1.3 Windows
As of early 2018, Slicer migrated to Qt5. Qt4 support was removed in version 4.11. See instructions at this labs page for the new requirements: https://www.slicer.org/wiki/Documentation/Labs/Qt5-and-VTK8
The prerequisites listed below are required to be able to configure/build/package/test Slicer.
- CMake >= 3.13.4
- Git >= 1.7.10
- Svn >= 1.7
- Qt 5.11: tested and recommended
- To build Slicer: install Qt using the distribution package manager.
- To package and redistribute Slicer: download and execute qt-unified-linux-x64-online.run, install Qt, make sure to select qtscript and qtwebengine components.
- GCC suite
- 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 build-essential 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
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 libxkbcommon-x11-0
sudo apt-get install libosmesa6-dev # Only for Ubuntu < 14.04.3
- For Qt5.5 on Ubuntu 16.04
sudo apt-get install libgstreamer-plugins-base0.10-dev
- Open a terminal and copy the command reported below
- Download stable version of CMake and extract the archive:
sudo apt-get install curl mkdir ~/Support && cd ~/Support curl -O https://cmake.org/files/v3.13/cmake-3.13.4-Linux-x86_64.tar.gz tar -xzvf cmake-3.13.4-Linux-x86_64.tar.gz
- Create symbolic links into
mkdir -p ~/bin for name in cmake ctest cpack ccmake cmake-gui; do ln -s ~/Support/cmake-3.13.4-Linux-x86_64/bin/$name ~/bin/$name done
See instructions reported in qt5-centos7/Dockerfile
- XCode command line tools must be installed:
- El Capitan is what most developers use.
- CMake 3.12.2 is recommended. Check the minimum required CMake version here
- Large File Storage for git is required. (brew install git-lvs)
- Qt 5: tested and recommended.
- Setting CMAKE_OSX_DEPLOYMENT_TARGET CMake variable specifies the minimum macOS version a generated installer may target. So it should be equal to or less than the version of SDK you are building on. Note that the SDK version is set using CMAKE_OSX_SYSROOT CMake variable automatically initialized during CMake configuration.
MacOSX 10.9.4 (Mavericks)
(1) Make sure to install this update: http://support.apple.com/kb/DL1754
(2) Use CMake 3.12.2 - it is known to be working and is supported (if you want to use CMake already installed on your system, 126.96.36.199 is known to work on Mac OS X 10.9.5)
- Mac Os X >= 10.5 (Leopard)
- CMake >= 2.8.9
- For Mac Os X >= 10.8 (Mountain Lion) and/or recent XCode >= 4.5.X - CMake >= 2.8.11 is required. See http://www.cmake.org/files/v2.8/cmake-2.8.11-Darwin64-universal.tar.gz
$ 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:
- XQuartz - For Mac Os X >= 10.8 (Mountain Lion) install XQuartz (http://xquartz.macosforge.org) to get X11 (no longer a default in OS X).
- Qt 4 >= 4.8.5. We recommend you install the following two packages:
Mac OSX 10.11 (El Capitan)
XCode up to version 7 is known to work for Slicer compilation. XCode 8 breaks things on several levels for now. Remember to install XCode command line tools (see above) if a reinstall for XCode is needed.
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 which patches it to work on El Capitan (see below).
- Install the OS, Xcode, and XQuartz (see MacOSX 10.10 above)
- Install Qt4 by running 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.
Mac OSX 10.12 (Sierra)
Similar to 10.11 (El Capitan), there are new issues with Qt4 (caused by Phonon). The GitHub user Cartr offered a patch to the brew team, and even though it was not integrated (the homebrew team decided to stop patching their recipe to encourage people to use Qt5), he turned his formula into a tap that can be installed (see below).
Follow instructions for 10.11 (Installing Xcode, XQuartz, run without TCL) but install Qt4 like shown below instead:
brew install cartr/qt4/qt xcode-select --install
Confirmed with Xcode:
- Version 8.1 (8B62) and cmake version 3.4.20151021-g8fbc8e
- Version 8.3.3 and cmake 3.5.2
Mac OSX 10.14 (Mojave)
Associated discussion topic is https://discourse.slicer.org/t/building-on-mac-10-14-mojave/4554/21
- Install Qt 5.11.2 using Qt Online Installer for macOS
- Install XCode:
- Build qt from homebrew
brew install qt ccmake -DCMAKE_OSX_DEPLOYMENT_TARGET=10.14 -DQt5_DIR=/usr/local//Cellar/qt/5.13.2/lib/cmake/Qt5 ~/slicer/latest/Slicer
- Explicitly set the SDK when running make
SDKROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk make -j20
- CMake >= 3.15.1
- Git >= 1.7.10
- CMake must be able to find git.exe and patch.exe. If git is installed in the default location then they may be found there, but if they are not found then either add the folder that contains them to PATH environment variable; or set GIT_EXECUTABLE and Patch_EXECUTABLE as environment variables or as CMake variables at configure time.
- Subversion (SVN) client: any SVN client that has command line tools
- NSIS (optional): Needed if packaging Slicer - Click here to download. Make sure you install the language packs.
- Qt5: Download download Qt universal installer from here and install Qt 5.15 along with qtscript and qtwebengine components. For examples of the installation procedure, see this step-by-step guide.
Tested and recommended build environment
- VS2017 (Visual Studio 15 2017 Win64)
- VS2019 (Visual Studio 16 2019 Win64)
- Older VS toolsets can be used with newer IDES
- When configuring Visual Studio installer, enable installation of Visual Studio 2017 (v141) or Visual Studio 2015 (v140) toolsets
- For older toolsets, must be set in CMake: Optional toolset to use (argument to -T) need to be set to v141 or v140
- Make sure you enable installation of component Programming languages / Visual C++ / Common Tools for Visual C++ (in some distributions, this option is not enabled by default)
- Qt 5.15
- CMake >= 3.15.1
Experimental/deprecated build environments
- VS2015 (Visual Studio 14 2015 Win64) Update 3
- Requires Qt 5.10.x to build due to QtWebEngine. For more details, read this step-by-step guide to download and install.
- Cygwin (untested, probably does not work)
- Cygwin suite (building with cygwin gcc not supported, but the cygwin shell environment can be used to run git, svn, etc).
