Octave - no syntax highligting

[hajgato]

Octave needs QScintilla2 to have syntax highlighting. QScintilla2 depends on Qt (can be used with both Qt4 and Qt5, and it installs itself into the original Qt directory. I did not investigate how could I install the necessary files to another directory, and if it is installed in another directory, how could be used. Its the fascinating world of qmake

[ocaisa]

I got around this by adding Qscintilla to the initial Qt install. The relevant bits are:

#QScintilla
qscintilla = 'QScintilla'
qscintilla_version = '2.9.2'

source_urls = [
    'http://download.qt.io/official_releases/qt/%(version_major_minor)s/%(version)s/',
    'http://download.qt.io/archive/qt/%(version_major_minor)s/%(version)s/',
    #Qscintilla
    'http://sourceforge.net/projects/pyqt/files/QScintilla2/%s-%s/' % (qscintilla, qscintilla_version),
]
sources = [
    '%(namelower)s-everywhere-opensource-src-%(version)s.tar.gz',
    '%s_gpl-%s.tar.gz' % (qscintilla, qscintilla_version),
]

and

# Install QScintilla (needed by Octave) by brute force
installqscintilla = "cd %(builddir)s &&"
installqscintilla += "cd %s_gpl-%s/Qt4Qt5 &&" % (qscintilla, qscintilla_version)
installqscintilla += "%(installdir)s/bin/qmake qscintilla.pro && make && make install"
postinstallcmds = [installqscintilla]

@ocaisa Where does it install QScintilla? To the origininal Qt directory, or somewhere else? I am not so happy if it installs to the original Qt directory.

[ocaisa]

Yeah, its a hack, it installs at the same time as Qt so adds the libs to the same directory

[boegel]

@ocaisa any reason why you're not including QScintilla as a dependency?

[ocaisa]

Because I don't know how to install Qt extensions without them ending up in the initial Qt install path.

@boegel @ocaisa I tried to look into this issue at the beginning, and I found that it is not possible to install Qt extensions to a separate directory without patching Qt. At least I was not able to figure out, although I did not spend too much time with this issue, as it was not crucial for me.
