Dependencies
The full set of dependencies for Krita 3.0 pre-alpha:
- Qt 5, at least 5.4 is required, but the newer the better. You need the following components:
- Core
- Gui
- Widgets
- Xml
- Network
- PrintSupport
- Svg
- Test
- Concurrent
- OpenGL (optional, but really, really recommended)
- Quick (optional, for sketch/Gemini)
- DBus (optional)
- X11Extras (only on Linux)
- The following KDE Frameworks:
- The following required packages
- Eigen3
- Exiv2
- lcms2
- GSL
- Boost (headers and the boost system library)
- zlib
- libtiff
- libpng
- libjpeg
- perl (need to check if this is really true, I doubt it)
- The following optional packages
- SharedMimeInfo
- Poppler
- OpenEXR
- pthreads (for G'Mic)
- openmp (for G'Mic)
- curl (for G'mic)
- libraw

Krita can be built successfully omitting several optional packages. KIO is for optional thumbnail integration with Dolphin. QtDeclarative is for Krita Sketch. Poppler is for PDF import. GSL is for the transform tool. Vc is for faster SIMD accelerated painting, and is necessary for a usable painting experience on anything but the smallest canvases. SharedMimeInfo is for determining file types. If you want to build Krita without these features, you can omit the package.

Sponsored Work
This is an index of work sponsored by the Krita community and the Krita Foundation. Note that the Krita Foundation (Stichting Krita) has been instrumental in fundraiser efforts around Krita. The first program, executed during the 2009-2010 timeframe, allowed Lukáš Tvrdý to work full-time on Krita for 24 weeks. This made a massive difference for Krita, solving hundreds of bugs and improving performance and usability of the canvas and many brushes to the level where Krita first became ready for (semi) professional use. Find more details here.
Subsequent fundraisers supported Dmitry Kazakov who brought openGL support to a new level and introduced advanced canvas operations like panning, mirroring and rotation and independent artist Timothee Giet who developed the "Comics with Krita" training DVD as well as a host of other video tutorials on Youtube.
