Hi there,

I recently made a guide for developing Krita with MSYS2 on Windows! The Goals:

• Start developing Krita in 5 minutes (minus download and compile time of course)

The guide: https://docs.google.com/document/d/1Se6 ... sp=sharing

But there are some things missing/incomplete/not working:

• VC is missing. I've managed to create a PKGBUILD for VC. Its not yet finished but will hopefully merged into the MSYS2 repository one day. https://github.com/kelteseth/MINGW-pack ... c/PKGBUILD . It would be greate if someone with more experience in writing PKBUILDS could test this!
• Add support for ninja for faster compiling to the guide
• Fix the "Krita cannot find any brush presets! Krita will now quit" error at startup.

Gonna bump this thread as it seems relevant, and it's for development purpose, but I have issues with this method.

I got as far as to QtCreator, so I'm having these issues -

D:\MSYS2\Projects\krita-original\krita\krita\data\CMakeLists.txt:20: error: install FILES given no DESTINATION!

D:\MSYS2\Projects\krita-original\krita\krita\pics\app\CMakeLists.txt:1: error: Unknown CMake command "ecm_install_icons".

Configuration failed.

So, there doesn't seem to be a good solution to this issue. I know ECM is ExtraCMake, but I'm not sure how to get it into MSYS2 development environment.

_Why_ don't you follow the instructions (https://phabricator.kde.org/source/krit ... /README.md)? _Why_ are you trying to use msys2? Your problem has _nothing_ to do with Krita development yet. You're still at the "learn how cmake works" stage. There is also nothing special about building Krita from Qt Creator on Windows; setting that up is like setting up any cmake based project on Windows, so learn about that first.

Tried that too, but also has complications. This is what I got. Got farther with the other instruction, but it didn't work. Well, at least I finally got the path part correctly, but it seem that it's not working well.

Run cmake from a shell that does not have sh.exe in your PATH.

If you want to use a UNIX shell, then use MSYS Makefiles.

That happens if you install Git for Windows and chose to add all the msys2 tools to the system PATH, which is a bad idea 99% of the time. Remove that folder from the PATH.

There is a build script in build-tools/windows that sets up its own PATH and does all the build steps for you. You can try to use that but that'll require a bit experimentation as I am too lazy to properly document it.

I gotten past that part, but bad news What now? :
