for monero gui in the readme is written Qt 5.9.7, still true, or better take 5.9.9, for development, to integrate UR for offline signing

make: monero-gui/src/p2pool/P2PoolManager.cpp:206:39: error: no matching function for call to ‘QProcess::startDetached() <- is this know or an issue I run only in my machine?

changed the line to: `started = m_p2poold->startDetached("start");` (The string "start" only to get it to build, no research or investigation done) and then it build complete.

vthor_: use Qt 5.15

after reading monero-project/monero-gui #4348#issue-2499389628 I wonder, if Qt 5.9.7 is indeed still correct or if I should use 5.15.15?

thank you

GUI ships 5.15, others aren't tested and the documentation probably isn't up to date

vthor: If you plan on doing anything webcam related with the GUI you're going to want to upgrade it to Qt 6 first. We can't ship portable Linux binaries with Qt 5's multimedia backend.

In fact, even if you use Qt 6, you'll want to write a custom V4L2 backend. You can copy the one from Feather.

tobtoht_: well I used until now 6.8.x

but monero-gui still on the 5.15 branch

and I wanted only "quick" finish milestone 4 of the XmrSigner CCS. I imagine it will not much tu upgrade to 6.8.x but I think that makes it a lot more dificult to get my PR then accepted. Additionally I have full migraine atm and can find the f... qt-opensource-linux-x64-5.15.15.run anywhere only the source. Maybe I make better a full stop to think for a moment. I discovered that in monero-qui, is almost all available in advanded of sending (and

I didn't want to mess with the UI either - changing the way things work in monero-gui). The the UR realated source I copied it from feather for the companion application and was planing to do that also in monero-gui. But now I'm not sure if I wook from there a custom V4L2 backend, will need to read the source again, but I think there was something where I was wondering why...

contrib/depends/patches/qt/v4l2.patch in feather source for that patch

"I imagine it will not much tu upgrade to 6.8.x " <- The build system work alone is probably a few weeks of works.

You can probably still install Qt 5.15 using your distro's package manager.

You could build UR into GUI without upgrading Qt, but it just won't work on Linux release binaries.

contrib/depends/patches/qt/v4l2.patch in feather source for that patch <- thank you :)

found Qt 5.15.2 in the Qt Maintenance tool, will using that for now how I find for 5.15.15 only sources

You could build UR into GUI without upgrading Qt, but it just won't work on Linux release binaries. <- this is the reason why cam is disabled for linux in monero-gui? But that means it would work during development on my machine but not on the release build, or will not work at all at the moment without modifications?

yes, it just won't work in the release build

okay, then I will simply do that at the moment and think about the isssue later, and after a upgrade to 6.8 I will go over it again. Well today I will get anyway not much done, my head is about to explode and weather (heat and pressure) and noise around me not helpful either. But I want today at least have everything compiling oob without any modifications and get it build in QtCreator, if not I go nuts.
