I already did this also, i have 12 core processor so i added -j12 in cmake, but no solution. Same problem exists, terminal getting crashed.That is not reducing the number of threads ;-) Use
-j1or-j2, this will reduce RAM usage considerably.wrote on 10 Oct 2023, 13:00 last edited by@sierdzio

Looks like you need more RAM.

Hi,
I have RAM-16GB, 12 core processor and created swap of size 8GB ?
16GB RAM is not sufficient ? or what could be the problem ? -

I increased my swap size again and it worked for me.
Thanks to all of you for your advice, finally i have successfully build and install Qt-6.5.2 in my Ubuntu PC.
I have successfully build and install QtCreator-11.0.3 also.
But now QtCreator-11.0.3 is not working properly, whenever i will click on gui components in left panel, QtCreator is getting crashed with message in terminal "Segmentation fault (core dumped)".
I am not able to drag and drop or put any gui widget in form(.ui file) in qtcreator, it's getting crashed immediately just after click on that.
What could be the error ? How to resolve this issue. -

If you want offline installer of just Qt Creator, then: https://download.qt.io/official_releases/qtcreator/11.0/11.0.3/

Hi, I have already downloaded qt-creator-opensource-linux-x86_64-11.0.3.run from link you have suggested for offline installer.
But when i am running this executable, it's asking for registration or license type of stuffs.
Why for opensource QtCreator it's asking registration ? Earlier it was not such type of case, previously i was using QtCreator version-4.6.1. -

As to "why" - well, that's what Qt Company came up with to coerce more people to buy licenses. Nothing we can do about it :-(
