You should have everything you need already except for the Python module aqtinstall. This module uses the same Qt repositories that the official Qt online installer uses, so there's nothing squirrelly going on.
Install the module from PyPi with:
Code:
sudo pip install aqtinstall
I prefer sudo because you don't have to mess with adding your home bin directory to your path to use the executable scripts.
Then run:
Code:
sudo aqt install-qt --outputdir /opt/qt6 linux desktop 6.7.2 -m qtimageformats qtshadertools qtwebengine qtpdf qtwebchannel qtpositioning
This will install the Qt6.7.2 pieces that Sigil needs to /opt/qt6. Change the location if you like, but you will have to modify the next command if you do. In an empty build directory run:
Code:
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH=/opt/qt6/6.7.2/gcc_64 <path to Sigil source>
Obviously change <path to Sigil source> to wherever you unzipped the Sigil source code.
If everything completes successfully, you should be able to run:
followed by:
Let me know how you get on. We can move this to its own thread if it becomes more involved.
