CMake

Work is a on going to get this build system functional!

Cmake is a cross-platform build system know to work on all major platforms we support (*nix, Windows, OSX).

CMake is an extensible, open-source system that has many powerful features. Those features include:

• Supports complex, large build environments. CMake has been proven in several large projects (KDE, ParaView, SecondLife, Scribus)
• Generates native build files (e.g., makefiles on Unix; workspaces/projects on MS Visual C++). Therefore, standard tools can be used on any platform/compiler configuration.
• Powerful system introspection abilities including the ability to find installed include files, libraries and executables. Also the ability to test the compiler for supported features.
• Integrated testing system called CTest.
• Integrated packaging system called CPack.
• Easy integration with CDash and Dart dashboard servers.
• Powerful scripting language with simple syntax.
• Supports in-place and out-of-place builds. Multiple compilation trees are possible from a single source tree.
• Can be easily extended to add new features.
• CMake is open source, under a liberal BSD license.
• CMake operates with a cache designed to be interfaced with a graphical editor. The cache provides optional interaction to conditionally control the build process.
• Ability to create Mac OSX Frameworks and Application Bundles.
• Supports adding complex custom rules to the build.

How you can help

We have completed the building of the CMakeLists.txt for almost everything needed. We are now working on get the build to compile properly. See below Testing/Using to help.

There is a separate CMake Tasks page with things that are left to do w.r.t. cmake building of Inkscape.

Using CMake to build Inkscape

Experience with Scribus strongly suggests using an "out of source"build arrangement. E.g.

mkdir buildinkscape
cd buildinkscape
cmake ./path/to/inkscape/sources
make

Using CMake to run tests

First, install Google Test framework by running download-gtest.sh in the main directory of inkscape source:

cd /path/to/inkscape
bash download-gtest.sh

Then, toggle the CMake config var "WITH_GTEST" to ON, e.g. by editing CMakeCache.txt, or by passing "-DWITH_GTEST=ON" to cmake. Don't forget to re-run cmake after the configuration change:

cd /path/to/buildinkscape
# modify CMakeCache.txt
cmake ../inkscape

Finally, run "make check" from same directory to run the tests:

make check

Configuring your build further

It is possible to change some more options of the build, e.g. whether to compile against GTK2 or GTK3 libraries. If you fiddle a lot with this, you may want to install the interactive cmake configuration tool "ccmake", like so:

ccmake screen capture

sudo apt-get install cmake-curses-gui
ccmake ../inkscape  # In buildinkscape folder

The ccmake utility will have features to re-run cmake for you before exiting.
For example you can use CMAKE_INSTALL_PREFIX option to install in a custom dir, and handle multiple Inkscape instalations.
Press enter on the line to edit.
Press again to save, when all your changes are done press c to configure, exit help and press g to generate.
After this you exit ccmake and can finish with make.

adding options to cmake

you can specify some variable on cmake invokation. i.e.

cmake .. -G "MinGW Makefiles" -DCMAKE_BUILD_TYPE=Debug

Useful CMake configuration variables include

• CMAKE_BUILD_TYPE: Either Release or Debug (a string).
• WITH_GTK3_EXPERIMENTAL: ON/OFF. Toggle between GTK2 or GTK3 ui toolkit.
• CMAKE_INSTALL_PREFIX: Path in which "make install" installs Inkscape.
