Start developing Krita on Windows in 5 minutes with MSYS2

1 Pre Requirements

Download and install MSYS2 x86_x64 from http://www.msys2.org/

• Start MSYS2
• Update the repositories
  • Run: pacman -Syu
  • Restart terminal. Ignore these errors:

“warning: terminate MSYS2 without returning to shell and check for updates again. warning: for example close your terminal window instead of calling exit”

There is a bug if you want to close the window it crashes. Nonetheless it should work!

• Run: pacman -Su
• Wait for the updates to be installed

2 Install Dependencies

• We cheat here because this can take some time depending on your internet connection and you don't have to do anything :)
  • Run:

pacman -S

3 Download Krita via git

• Open MSYS2 shell
• Run: cd to/your/desired/destination
• Run: git clone git://anongit.kde.org/krita
• You also could use a GUI for this like GitExtentions!

4 Compiling Krita

1. Start QtCreator (C:\msys64\mingw64\bin\qtcreator.exe) and open the CMakeLists.txt from the krita folder via “Open Project” 2.Configure the project as 64bit. Click Configure project

2. Wait for “CMake Project was parsed successfully” in the General Message tab. This can take some time!

3. Go to “Projects” on the left and under "Build Steps"
   1. Change the CMAKE_INSTALL_PREFIX to a writable location like next to your source code! This is due to how plugins work in Krita More info here!
   2. Press the “Add Build Step” Button
      1. Select Build in the dropdown
      2. remove the all checkbox and enable the install checkbox
4. Compile via the big green arrow on the bottom left
5. Compiling can take quite some time. It takes at least 15-20 minutes on my 8 Core Ryzen 1700
6. Happy Hacking!

//Optional add the bin folder to your windows path to open Qtcreator via windows search ;) C:\msys64\mingw64\bin
