[Interest] Compile Qt 6.2.1 from source

[Mitch Curtis]

For some reason when I reply all to your messages they only go to you. So, explicitly adding the interest list back in:

You could try using less “jobs” when building:

I’ve had to do this on my macOS machine to allow me to still use it while building.

Hi

The compilation failled twice, I'm using the dev branch and developer build:


$ ../qt5/configure -developer-build -- -D QT_BUILD_TESTS_BY_DEFAULT=OFF

 $ cmake --build . --parallel
bulding fails at aprox. 36%, the pc runs out of memory and freezes.

I'm using a fairly decent pc, with core i7 and 16GB ram, linux mint 20.2. I can see from linux monitor that  memory is used up to 99% plus swap memory of 16GB used up to 100%.

I'm using cmake version 3.21.3, I had to compile it from source, the first time I tried using cmake from linux repo
I got an error saying that cmake version was too old.

Any ideias ?

Cheers
João

Thank you

It's equal to building Qt5, wich I did before, I thought that for Qt6 git sources were no longer available.

Cheers

Hi

I have a commercial Qt license, can I compile Qt 6.2.1 branch from source ?
I have reported some bugs that are now fixed in that branch, would like to try it.
I've been searching codereview repositories, but I'm a bit lost.

Just build the 6.2 branch from git.  https://wiki.qt.io/Building_Qt_6_from_Git
Of course by the time 6.2.1 is released, it will have many more changes.  You can keep pulling periodically to follow along.
