VTK/Configure and Build

Introduction

Hello! Welcome to the wiki.

This page is applicable for VTK 6.0 and above. For earlier versions, refer to a deprecated version of this document.

This page describes how to configure and build VTK, with several popular options turned on.

Prerequisites

• The VTK build process requires CMake version 2.8.8 or higher and a working compiler. On Unix-like operating systems, it also requires Make, while on Windows it requires Visual Studio (8 or later).

• Building VTK with Qt is a common use case for the creation of nice user interfaces. Using Qt 4.8.* is recommended, but earlier versions and Qt 5.* are in various stages of support. Visit the Qt download page to get a copy of the source code or installer. Either the LGPL or commercial versions of Qt may be used.

Download And Install CMake

CMake is a tool that makes cross-platform building simple. If CMake does not exist on the system, and there are no pre-compiled binaries, use the instructions below on how to build it. Use the most recent source or binary version of CMake from the CMake web site.

Using Binaries

There are several precompiled binaries available at the CMake download page.

On Unix-like operating systems Let's say on Linux, download the appropriate version and follow these instructions: Download: http://www.cmake.org/files/v2.8/cmake-2.8.8-Linux-i386.tar.gz cd $HOME wget http://www.cmake.org/files/v2.8/cmake-2.8.12.2-Linux-i386.tar.gz mkdir software cd software tar xvfz ../cmake-2.8.12.2-Linux-i386.tar.gz Now you have the directory $HOME/software/cmake-2.8.12.2-Linux-i386/bin, and inside there are executables cmake and ccmake. You can also install CMake in the /usr/local or /opt by untarring and copying sub-directories. The rest of the instructions will assume the executables are in your $PATH.

On Windows Download the installer: http://www.cmake.org/files/v2.8/cmake-2.8.8-win32-x86.exe Follow the installation instructions On Windows, if you are not administrator Download: http://www.cmake.org/files/v2.8/cmake-2.8.8-win32-x86.zip Uncompress into some directory Optional: create a shortcut on the desktop.

Build Your Own CMake

On Unix-like operating systems Download the source code: http://www.cmake.org/files/v2.8/cmake-2.8.12.2.tar.gz cd $HOME wget http://www.cmake.org/files/v2.8/cmake-2.8.12.2.tar.gz tar xzf cmake-2.8.12.2.tar.gz cd cmake-2.8.12.2 ./configure --prefix=$HOME/software make make install Again, you can install it in /usr/local or /opt by changing the prefix.

On Windows To build CMake on windows, a previous version of CMake is required. This can be downloaded from the Cmake download page: [1].

Download VTK Source code

Download a Release

Download a VTK release from the VTK Downloads page.

Checkout the VTK Repository with Git

If you want the nightly updates of VTK, this is your best bet. Checking out from source control also greatly facilitates the process of contributing back. Note that you may need to download and install a git client, here: [2]

Tip: Check out the VTK Git landing page.

On Unix-like operating systems Prepare directory for download # mkdir $HOME/projects # cd $HOME/projects To download the source code # git clone git://vtk.org/VTK.git # cd VTK To update the code # git fetch origin # git rebase origin/master

On Windows We recommend msysgit. msysgit provides an msys shell that has the appropriate environment set up for using git and its tools.

Configure VTK with CMake

• Always use a separate build directory. Do not build in the source directory.

On Unix-like systems Use ccmake (Curses CMake GUI) from the CMake installed location. CCMake is a Curses based GUI for CMake. To run it go to the build directory and specify the VTK source directory as an argument. mkdir $HOME/projects/VTK-build cd $HOME/projects/VTK-build ccmake $HOME/projects/VTK About CCMake (Curses CMake GUI) Iterative process. Select values, run configure (c key). Set the settings, run configure, set the settings, run configure, etc. Repeat until all values are set and the generate option is available (g key). Some variables (advanced variables) are not visible right away. To see advanced varables, toggle to advanced mode (t key). To set a variable, move the cursor to the variable and press enter. If it is a boolean (ON/OFF) it will flip the value. If it is string or file, it will allow editing of the string. For file and directories, the <tab> key can be used to complete. To search for a variable press '/' key; to repeat the search, press the 'n' key.

On Windows Use CMakeSetup from the CMake install location. Make sure to select the appropriate source and the build directory. Also, make sure to pick the appropriate generator. Some CMake versions will ask you to select the generator the first time you press Configure instead of having a drop-down menu in the main dialog. About CMake GUI Iterative process. Select values, press the Configure button. Set the settings, run configure, set the settings, run configure, etc. Repeat until all values are set and the OK button becomes available. Some variables (advanced variables) are not visible right away. To see advanced varables, toggle to advanced mode ("Show Advanced Values" toggle). To set the value of a variable, click on that value. If it is boolean (ON/OFF), a drop-down menu will appear for changing the value. If it is file or directory, an ellipsis button will appear ("...") on the far right of the entry. Clicking this button will bring up the file or directory selection dialog. If it is a string, it will become an editable string.

VTK Settings

Variable	Description
BUILD_SHARED_LIBS	If ON, use shared libraries. This way executables are smaller, but you have to make sure the shared libraries are on every system on the cluster. This option should be set to ON if you plan on using plugins for ParaView (there ways to use plugins in static builds of ParaView for advanced users).
BUILD_DOCUMENTATION	If ON, build the documentation target, DoxygenDoc
BUILD_TESTING	If ON, build the tests for submission to dashboards, or just run them locally with ctest -A
CMAKE_BUILD_TYPE	Should be Release or Debug. If Debug, build with debug symbols. This will run more slowly, but will be more useful if you plan to use a debugger.
CMAKE_INSTALL_PREFIX	Specifies where make should put the libraries when the make install command is run.
TODO	Put the rest of the prominent variables here
QT_QMAKE_EXECUTABLE	Path to Qt's qmake executable (such as /usr/local/bin/qmake). CMake uses this to locate the rest of the required Qt executables, headers and libraries.

Configure with Qt

Note: This step is not absolutely necessary, but useful for anyone hoping to integrate VTK with Qt for a pretty graphical user interface. Depending on your platform and the desired Qt version, this can be a somewhat arduous process, especially if you need to build Qt from source. We recommend using Qt installers along the way whenever possible.
