 Posted: Sat Feb 17, 2018 6:45 pm Post subject: [Solved]Help with writing ebuild dependent on running qmake5 |
 |
|
I'm trying to write an ebuild for renderdoc (including the Qt5 GUI) and it's working for the most part. The issue I have is that it uses the qmake that is set via qtchooser, that for me is qmake4. I need the ebuild to automatically choose qt5. RenderDoc is built using CMake, which makes it a bit confusing, I'm having trouble understand where to set what...

The QRenderDoc CMakeLists.txt specifies the QMAKE_QT5_COMMAND variable to "qmake", and I've tried setting it specifically in the ebuild, but it doesn't work. You can see the file here:
https://github.com/baldurk/renderdoc/blob/v0.x/qrenderdoc/CMakeLists.txt
Do I need to patch the CMakeLists.txt, or is it possible to just set a smart variable somewhere, and it automatically solves the problem?

I tried setting the QT_SELECT variable in the ebuild and that seems to do the trick. I don't know if that's an OK way of doing it, but there seems to be a bunch of official ebuilds doing it.

export QT_SELECT=qt5? (example /usr/portage/media-video/vlc/vlc-2.2.6.ebuild)

Thanks, QT_SELECT did the trick!

Using QT_SELECT might not be the best of ideas:

This seems to work for me when building anything depending on Qt. |

I tried to make a patch that did that, but couldn't get it to work... Perhaps I should try again. I also thought about reporting a bug upstream, so they fixed it there instead.
