pyqt5 picore 13.0.3 rpi 4

[ketank]

btw, why are you using cmake/make rather than configure/make?

just following https://wiki.qt.io/Building_Qt_5_from_Git#Getting_the_source_code

I realized that ninja is the way to go.
make failed for me and then switched to ninja.

was using make -j$(nproc) and it crashed with excessive memory usage!!!

running again

Thank you for all you support especially Rich and Juanito

1. I installed qt5 and built it.
2. set the path to qmake
3. installed pyqt5 using pip.

Interesting problem though - the X has stopped working.
I see following error -

failed in waitforX

NOTE: It was working before the QT5 installation as I know...

Once I have it working, will test if I can really have the qt5 UI working...

any ideas how to fix the above issue will help.

The additional components I installed were

Xorg-3d.tcz
Xorg-fonts.tcz

it was part of the required libraries for building qt5 as per http://tinycorelinux.net/11.x/x86_64/tcz/src/qt-5.x/compile_qt-5.x

Hi ketank
My guess is  Xorg-3d.tcz  is causing the error.

Hi Rich,

Thank you for the help.
After second reboot, X is working fine.

Tried a basic QT app and I need to have the external drive connected to run the applications. If not, it fails with the libraries not found.
Seems some hard links while installing the PyQt5..
