Thanks Mike - I hadn't noticed that bug report.

The configuration failure for Qscintilla is due to -lQtOpenGL. I forced the outcome of the configuration test to be true (ie imposing octave_cv_lib_qscintilla=yes): Octave compilation ran through ok and the editor is back and functional. So, I'm happy now even if libnvidia-glcore.so seems broken on my system.

Guillaume, there is a separate bug about falling back to the system editor if the GUI is built without Qscintilla, that has not yet been addressed by anyone interested (because most people are happy with the built-in editor). See bug #39179.

While I'm waiting for a new version of the nvidia drivers to fix the issue, I am having problems setting up another editor to use.

I've added an entry in ~/.octaverc:

but I get at startup the following error message:

EDITOR() returns the content of the system variable $EDITOR.

Invoking "edit" at the command line from the desktop does not do anything - it opens the chosen editor when running Octave with --no-gui.

Ok, closing as invalid due to unrelated system library problems.

Fixed the typo here:

Ah, thanks Mike! config.log has:

so it seems that the problem comes from the update of the nvidia driver that also took place today (to version 367.27).

[Aside from this, I still think there is a typo in configure such that it should be:

instead of:
OCTAVE_CONFIGURE_WARNING([warn_qscintilla])

Works for me. Some more details are needed here. The best details would be the snippet from config.log that explains why the test failed to check for qscintilla. Searching for that "checking" string in config.log should get you to the right place.

As of today, Octave compiled without the GUI editor and ./configure now displays:

while libqscintilla-devel and libqscintilla2-11 are installed (2.8.2-2.1.8).

There has been an update of libqt4-devel to version 4.8.6 on my system today so I assume it might be related.

I tried to compile the following:

with:

and it compiles and runs fine.

Looking at configure/configure.ac, I notice that the warning "Qscintilla library not found; disabling built-in Qt GUI editor" is not displayed in my case but it might be due to a typo warn_qscintilla -> warn_qscintilla_editor.
