qscintilla2 fails to build on 10.11: sip files generating qt5 API, but only qt4 installed

[ejtttje]

When generating the python bindings, the sip files all die with error:

./sipQsciQsciLexerCSharp.cpp:194:43: error: no viable conversion from 'const QMetaMethod' to 'const char *'
        QsciLexerCSharp::disconnectNotify(a0);
                                          ^~
/Volumes/Xcode/Brew/Cellar/qt/4.8.7/lib/QtCore.framework/Versions/4/Headers/qobject.h:291:47: note: passing argument to parameter 'signal' here
    virtual void disconnectNotify(const char *signal);
                                              ^
./sipQsciQsciLexerCSharp.cpp:212:40: error: no viable conversion from 'const QMetaMethod' to 'const char *'
        QsciLexerCSharp::connectNotify(a0);
                                       ^~
/Volumes/Xcode/Brew/Cellar/qt/4.8.7/lib/QtCore.framework/Versions/4/Headers/qobject.h:290:44: note: passing argument to parameter 'signal' here
    virtual void connectNotify(const char *signal);
                                           ^

QT4 used the char* argument for these methods, QT5 switched it to use QMetaMethod instead.
So it looks like sip is generating QT5 calls even though I only have QT4 installed? Not sure if this is a bug/issue with sip, or something in the build configuration for qscintilla...

Can you share the output of brew gist-logs qscintilla2 please?

[apjanke]

I'm seeing a similar error on my 10.11 beta test box. Here's my brew gist-logs.

I'm seeing this (exact same thing) on os/x 10.10.5

[ecerrillo]

Same here!

[tdsmith]

¯_(ツ)_/¯ I don't know how to debug this. It looks like everything is configured correctly: https://gist.github.com/anonymous/d190af428dff04c61643#file-04-python-L15-L30

I suggest reaching out to the qscintilla developers. It looks like it's been raised on this thread: https://www.riverbankcomputing.com/pipermail/qscintilla/2015-September/001067.html -- the correct qmake is being invoked and PyQt4 is being correctly selected.

[schoeps]

I can build qscintilla2 on El Capitan without the python bindings which I do not need (for Octave). May I suggest that the user can disable the python bindings? see e.g. https://gist.github.com/6d3f1008b9912f70f7ce

Ran into this, I then bumped my local formulae of pyqt and qscintilla2 to versions 4.11.4 and 2.9 respectively and had no problems compiling/installing (even on OS X 10.7). Not sure if this addresses this particular issue, but it is worth noting that the version bumps may be a good first step towards a resolution.

[apjanke]

That looks like a fix. If I bump both versions, they build and install on OS X 10.11 for me. Submitting PRs for the version bumps...

#44726

[ecerrillo]

It works now!

[McPo]

I made the changes referenced in the PR, and disabled the OSX sandbox.

[boltomli]

I rebuilt pyqt and sip, etc. then install 2.9 successfully. You might try that.

[UniqMartin]

The qscintilla formula has been updated to 2.9.1 very recently. Closing as apparently this should resolve the issue reported here. (Please report back if that's not the case.)
