Re: GUI compilation failing with Scintilla

[Daniel J Sebald]

Laurent,

I eventually figured out on my system how to upgrade to qscintilla 4/5. 
 (Version 3 was on my system and that has the header file with the 
::findFirst having less arguments.  I think you might have simply have 
gotten lucky by deleting the extra argument and running with the Qsci 3 
library.)  I downloaded the latest Qsci, but altered the instructions 
slightly because "qmake" on my system was associated with Qt 3.3 and 
didn't work with Qsci 4/5.  I then found in the repository that qmake 
version 4/5 is called qmake-qt4, so this is what worked on my system:

    cd Qt4Qt5
    qmake-qt4 qscintilla.pro
    make
    make install

I verified Qt 4.7.4 and Qsci 2 8.0.2 are linked in.

Unfortunately, this hasn't improved anything; I still get the Welcome to 
Octave! infinite loop.  So, I went to the manual creation of the 
"default-qt-settings" that several have described on the Maintainers 
list and got a little further:

 /usr/local/src/octave/octave-cellstr/octave/build3/run-octave
/usr/bin/ld: cannot open output file 
/usr/local/src/octave/octave-cellstr/octave/build3/src/.libs/15924-lt-octave: 
Permission denied

when running as a user (as opposed to root... running as root still 
fails).  Why the hidden directory for the libs?

I installed octave and launched.  Now I get the Welcome to Octave screen 
again which doesn't go away.  I've tried other variations, but none worked.

Operation seems a little dodgy and I'm wondering if I have the right 
versions of toolkits.  Seeing so many warnings about "this" pointer 
shadowing when compiling makes me wonder.
