Build is currently failing for me, the initial checks, and exception is as follows:

I suspect a temp fix might be building with -Wno-error=sfinae-incomplete. I've seen some mention of this issue both on QLC+'s forum (https://www.qlcplus.org/forum/viewtopic.php?t=18575) and on some other sites generically about this issue croppping up since GCC16.

qt6-svg is also needed at runtime

Also depends on libQt63DCore.so.6 at runtime, which is in qt6-3d (only a make dependency right now)

The desktop files exec command semms to not match anymore for qlcplus in version 5. This makes the launcher dissapear and breaks it. The executable of version 4 was called qlcplus and with version 5 my executable is called qlcplus-qml. It seems caused by upstream. There is a module named qlcplus-qml, but the desktop file uses the previous versions name.

Now this might be intentional by upstream, to continue official linux support for version 4 instead of version 5, although version 5 is officially released.

So all in all I try to correct this upstream, but wanted to let you know in case you have a different view on things.

Best wishes, Tobias

qt5-tools seems to be missing from the build dependencies.

I got the error ./translate.sh: line 15: LRELEASE: lrelease not found during build

Your PKGBUILD failed for me:

However adding

options=(!lto)

between the 'sha512sums' and 'prepare()' lines in the original PKGBUILD file worked.

Thanks for the hint!

Disabling lto seems to fix it (I use my own pkgbuild: http://0x0.st/Kujg.txt)

I just triedy it one more time. Same problem here, currently I dont hava a solution. Maybe an upstream problem?

It seems to be a cmake problem...

Build is failing here... Can I help debug?

qt5-websockets should be moved to depends, as it's required at runtime as well.
