As Dan wrote in comment #1.

This is not a bug.

So please close this.

@Mike: thank you very much for you help (comment #5).
It fixed the QT5 problem for me.

Can you edit also https://wiki.octave.org/Octave_for_Debian_systems according to comment #5?

Can this report be closed as fixed?

Now that you mention it, I too recall some problems installing the Qt help tools.  I'm not sure exactly which package it was, but "qttools5-dev-tools" rings a bell.  I went to the Synaptic Package Manager (Mint, based on Ubuntu) and some package indicated installed, but instead of a green box, it was grey with an exclamation point in it.  I simply uninstalled that and another nearby grey package and re-installed and things worked fine.

I followed the instruction

The tools you indicated were already installed.

(qtcore tools is installed at gnuplot build-dep install.)

However, some troubles happened after install.
(That breaks my wine install)

In struggling stage, I perhaps lost Qt5Help dev tool.
I installed qttools5-dev-tools to Ubuntu 16.04 on WSL
(Windows Subsystem on LInux)  in my home PC.
As you said, qttools5-dev-tools installs Qt5Help dev tools.

I once remove qttools5-dev-tools and re-install it tomorrow.

Tatsuro - on Ubuntu you should only need to install the following Qt 5 packages

  • libqt5opengl5-dev
  • libqt5scintilla2-dev
  • qtbase5-dev
  • qtbase5-dev-tools
  • qttools5-dev
  • qttools5-dev-tools

The Qt5Help library is provided by the 'qttools5-dev' package.

I pushed the following changeset to disallow using both --gui and --no-gui-libs and to also exit if --gui is used when Octave is not built with the GUI.

I write my workaround stable octave work again.

For Ubuntu 16.04 distribution , for Qt5Help, only run-time libraries are available. One have to construct dev kit using source of qttools.



Archive it and copy header files for Qt5Help to standard location same as other Qt5 header files. Some header files are the indication to header files in src/assistant. Merger header file from src/assistant.

Copy another pkg-config file to Qt5Help.pc and modify it for Qt5Help.

Two symlinks were required in my case.

sudo ln -s  /usr/lib/x86_64-linux-gnu/libQt5Help.so.5.5.1 /usr/lib/x86_64-linux-gnu/libQt5Help.so
sudo ln -s /usr/lib/libqt5scintilla2.so.12.0.1 /usr/lib/libqscintilla2-qt5.so

That's all my workaround for new stable source build.
(Ubuntu 16.04)

Thanks. Perhaps Qt for Ubuntu 16.04 is incomplete.
libqt5help5 is installed but there is not Qt5Help.pc nor include files.

There seem to be no dev packages.

I will struggle for qt.

Anyway pleas close this tracker.

The fact that the GUI is not being built in your case is not a bug.  There has a been a recent addition of embedded Documentation via the octave_interpreter.qhc and octave_interpreter.qch files.  This requires some additional Qt features, in particular QHelpEngine, QHelpSearchEngine, etc.  These new features appear in the package Qt5Help.  The configure is reporting that you don't have this package, so you must install it.

However, the poster's original discussion list message was:

I have tried to execute octave gui

./run-octave --gui

But CLI octave start.

which I'm opening for discussion as a bug.  My experience with command line options (in Unix) makes me think the program should fail to execute and return an error message if the --gui option is given and no GUI is available.
