#894 Can't compile Tulip with QT6 enabled

[Andre Maute]

On a recently updated Fedora 38 with installed GLEW libs I encounter build errors
when compiling with QT6 enabled

Best Regards
Andre

essentially I'm doing

tar xvfz tulip-5.7.3_src.tar.gz 
cd tulip-5.7.3/
mkdir build
cd build/
cmake -DTULIP_USE_QT6=ON -DCMAKE_INSTALL_PREFIX=/home/user/opt/tulip-5.7.3 ..
cmake --build .

this will error with

I will be out of my office until the beginning of January.
As we have only validated the Tulip build with Qt 6 up to the 6.4 version,
I may just suggest you to try to replace the file library/tulip/gui/include/tulip/GlSimpleEntityItemModel.h by the one in attachment.

This worked, thank you very much
And somehow I can't reproduce the Crash which I reported here
https://sourceforge.net/p/auber/bugs/893/
any more.

[Andre Maute]

no it is still still somehow reproducible, QT6 doesn't help!
