Because of an annoying audio issue, I had to go back to using an out-of-date linux distribution (Fedora 40, in case it matters). I ran into problems when trying to compile SC as the code seems incompatible with the version of qt6 (6.8.2) which is available. I tried downloading and installing directly and have 6.9.1 installed. However when I try to point cmake to use this version, instead of the system one, it doesn’t work:
cmake -DCMAKE_PREFIX_PATH=/home/oded/Documents/Qt/6.9.1/gcc_64/lib ..
But cmake still uses the system version.
For the moment I reverted back to version 13.1 and qt5. which seems to work. but I’m still not sure why the flag did not do the job.
Also, not sure who is maintaining the linux readme on github - a minor correction
dnf groupinstall "Development Tools"
should be
dnf group install development-tools
thanks
Hey!
Qt6 is only supported for 3.14 and later - can you say which specific version/commit you are on? 3.14-rc1?
Can you share the error message?
Currently we are only testing with qt 6.7 and haven’t run any tests with qt 6.8 or qt 6.9, but I don’t have any problems with qt 6.9 on my machine.
I do not have problems with vanilla Fedora 42. Which problems are you facing, this could be relevant for the 3.14 release.
Have you tried clearing the build directory before configuring the build? Also I am not sure what exact directory is needed here. How did you download the qt binary distribution?
Can you make a PR? 
(I was travelling so only got back to it now).
After cleaning the build directory, I was indeed able to make and install version 3.15-dev. Light testing suggests it is running fine but I do get two error messages:
(scide:15765): Gtk-WARNING **: 09:14:03.888: Theme parsing error: gtk.css:7470:228: Missing closing bracket for :not()
Release of profile requested but WebEnginePage still not deleted. Expect troubles !
Regarding the audio issue I have that requires me to stick with an old fedora version. The problem is not SC specific. it affects all audio applications when I use an external USB device. I suspect it is some issue with the kernel: everything is fine on kernel 6.8.5. I raised this (but it seems that the problem is some strange interaction between my laptop, the interface, and something in the audio system).
Finally, I’m not familiar enough with GitHub - what is a PR and how to a make it to get the correction into the linux readme?
Thanks
