We are trying to build the last version of Qt ( qt-15.5.0 ) from the sources on Ubuntu 20.04. Everything is running fine until we get the following error:
Project ERROR: Building QtQml requires Python.Python is avalaible ( version 3.8 ), we even tried alias python=python3 and adding the path to python to $PATH but it didn't help. We can't find any info on this specific problem.
What we did:
$ wget http://download.qt.io/official_releases/qt/5.15/5.15.0/single/qt-everywhere-src-5.15.0.tar.xz$ ./configure -prefix /username/dev/libraries/qt-5.15.0/install -xcb$ make -j8$ sudo make install
