Hi,
it is like shown below.
1. Compile and install Qt. That creates an installation directory (e.g.
/usr/local/Trolltech/Qt-4.x.y or /usr/local/Qt-5.x.y).
2. Compile the QScintilla C++ part for each Qt installation
3. Have a virtualenv for the relevant Python/Qt combination (note PyQt4 and PyQt5 can be
installed in parallel).
4. Compile PyQt with something like
export PATH=/usr/local/Qt-5.4/bin:~/py3qt50env/bin:$PATH
~/py3qt50env/bin/python configure.py -b ~/py3qt50env/bin/ -v ~/py3qt50env/pyqt5sip -c -j8 --
confirm-license
(all on one line)
