Build#

Platform Notes#

At least C++11 64-bit compiler support is required.

Build requirements#

OS X#

  • MacOS 11 or newer

  • Apple clang 9.0.0 or newer

  • Qt 5.15 or later

    • Download and run the desired Qt 5.x or 6.x installer. Make sure to turn off other versions and system configurations to save space and build time. Configure CMake for Qt 5. Optionally, install Qt through the package manager, brew.

      To install Qt 5, the command is:

      brew install qt@5
      

      To install Qt 6, the command is:

      brew install qt@6
      

      The installation directory for the CMake variable Qt_PATH will then be /usr/local/Cellar/Qt/_TYPE_QT_VERSION_HERE_.

Windows#

  • Tested on Windows 10

  • Visual Studio 2017 or 2019

    • Using 2017, be sure to change the CMake platform to x64.

  • Qt 5.15 or later

    • Download and run the Qt 5.15 installer. Make sure to turn off other versions and system configurations to save space and build time.

Linux#

  • Tested on Ubuntu 16.04 LTS, 18.04 LTS, 22.04 LTS, OpenSUSE Leap 42.1, Arch Linux

  • gcc 7+

  • Qt 5.15 or later

    • Download and run the desired Qt 5.x or 6.x installer. Make sure to turn off other versions and system configurations to save space and build time. Optionally, install Qt through your distro’s package manager instead(apt on Ubuntu/Debian, pacman on Arch).

      To install Qt 5, the command on Ubuntu/Debian is:

      sudo apt-get install qt5-default
      

      To install Qt 6, the command on Ubuntu/Debian is:

      sudo apt-get install qt6-base-dev libqt6svg6-dev
      

      The installation directory for the CMake variable Qt5_DIR(for Qt5) or Qt_PATH(for Qt6) will then be /usr/lib/x86_64-linux-gnu/cmake/.

      To install Qt 5, the command on Arch is:

      sudo pacman -S qt5-base
      

      To install Qt 6, the command on Arch is:

      sudo pacman -S qt6-base
      

      The installation directory for the CMake variable Qt5_DIR(for Qt5) or Qt_PATH(for Qt6) will then be /usr/lib/cmake/.

All Platforms#

  • CMake (platform independent configuring system that is used for generating Makefiles, Visual Studio project files, or Xcode project files)

    • Tested with 3.4 and newer

    • Root cmake file is Superbuild/CMakeLists.txt.

    • Building in source directories is not permitted.

    • Make sure BUILD_SHARED_LIBS is on (default setting).

CMake Build Generators#

  • Windows

    • Visual Studio 2017 & 2019

  • OS X

    • Unix Makefiles

    • Xcode

  • Linux

    • Unix Makefiles

Configuring CMake#

Run CMake from your build (bin or other build directory of your choice) directory and give a path to the CMake Superbuild directory containing the master CMakeLists.txt file.

A bash build script (build.sh) is also available for Linux and Mac OS X to simplify the process. Usage information is available using the –help flag:

./build.sh --help

For example, on the command line if building from the default SCIRun bin directory:

cd bin
cmake ../Superbuild

The console version ccmake, or GUI version can also be used. You may be prompted to specify your location of the Qt installation. If you installed Qt in the default location, it should find Qt automatically.

Configuring SCIRun with Qt 5#

Building SCIRun with Qt 5 requires additional input. Use the Qt5_PATH CMake variable to point to the Qt 5 build location. Look at the Qt install steps above for information about the directory. This can be done through the command line with a command similar to:

cmake -DQt5_PATH=path_to_Qt5_build/ ../Superbuild/

Or they can be set in the CMake GUI or with the ccmake function.

The command will be similar to the following:

cmake -DQt5_PATH=path_to_Qt5/5.15.1/clang_64/ ../Superbuild/

Configuring SCIRun with Qt 6#

Building SCIRun with Qt 6 requires additional input. Set the Cmake variable SCIRUN_QT_MIN_VERSION to 6.X.X, where the version is less than the installed Qt 6 version. Use the Qt_PATH CMake variable to point to the Qt 6 build location. Look at the Qt install steps above for information about the directory. This can be done through the command line with a command similar to:

cmake -DQt_PATH=path_to_Qt6_build/ ../Superbuild/

Or they can be set in the CMake GUI or with the ccmake function.

The command will be similar to the following:

cmake -DQt_PATH=path_to_Qt6/6.4.2/clang_64/ -DSCIRUN_QT_MIN_VERSION="6.3.1" ../Superbuild/

Configuring SCIRun with OSPRay#

To use the OsprayViewer module, SCIRun needs to download and install Ospray during the build process, which is off by default. This is enabled with the WITH_OSPRAY flag. In the command line, it would look like:

cmake -DWITH_OSPRAY=True ../Superbuild/

Building SCIRun#

After configuration is done, generate the make files or project files for your favorite development environment and build.

From the same command line, you can build with:

make

Append -jN, where N is the number of threads, to build multi-threaded. Note: A common problem during the first build is the Python build fails with multi-threading. If this happens, rebuild single-threaded.

Following the previous example, the SCIRun application will be built in bin/SCIRun.

Partial Rebuild#

After SCIRun has finished building externals from the bin/ folder, you can recompile just the internal SCIRun code by building in the bin/SCIRun folder. In the command line, it would look like:

cd bin/SCIRun
make

Append -jN, where N is the number of threads, to build multi-threaded.

Tagging Releases#

On an OSX system, run script release.sh in the src directory with the release name in format beta.XX as a parameter.
