Question can you help me to solve this problem?
If you want to install QScintilla for Qt5, you will have to tweak the
source code a little to get things to work properly.
So, starting from some clean sources, open up the
Qt4Qt5/features/qscintilla2.prf file in a text editor, and replace each
line that looks exactly like this:
LIBS += -lqscintilla2
with this:
LIBS += -lqscintilla2_qt5
This is to ensure that you can safely install QScintilla for both Qt4
and Qt5.
For the same reason, open the Qt4Qt5/qscintilla.pro file and replace
this line:
TARGET = qscintilla2
with this:
TARGET = qscintilla2_qt5
Once that has been done, you need to make sure that the correct features
file will be found (this is the most likely cause of your build errors).
So before you start re-building anything, do the following:
$ cd Qt4Qt5
$ export QMAKEFEATURES="$PWD/features"
You should also remove any QScintilla libs that you installed previously
(i.e. the libqscintilla2.so* files that probably ended up in
/usr/lib64). These files will currently have the same names as those
used by Qscintilla for Qt4, which is why the changes made above are needed.
With that done, re-build QScintilla2, and then have another go at
building the Qscintilla Python bindings.
