[Slackbuilds-users] QScintilla2 for Python3 and PyQt5

[Benjamin Trigona-Harany]

I'm trying to write a SlackBuild QScintila2 for Python 3 and PyQt5 and can't 
seem to get past a particular stumbling block.

Anyone have any suggestions for resolving the error showing in the attached 
error.txt file? The SlackBuild and patch file are also attached and the source 
is from https://sourceforge.net/projects/pyqt/files/QScintilla2/
QScintilla-2.10.2/QScintilla_gpl-2.10.2.tar.gz.

This is on a clean copy of Slackware64 14.2 (clean other than python3-PyQt5 
and its dependencies). 

There's lots of prior art out there for other distros but nothing I can find 
regarding this particular error.

Thanks, Ben
