Re: Unable to install 4.0 with Ubuntu

[Curt Carpenter]

Thank you both for your assistance.  Octave 4.0 successfully installed with GUI on this try.

For future Octave users like that may want to install Octave 4.0 under Ubuntu 14, here is a
summary of what worked for me:

    o  Download Octave 4.0 and extract it into a directory of your choice.

    o  Remove any installed versions of Octave on your Ubuntu system

    o  Open a terminal and execute
            sudo apt-get install  libqt4-dev libqscintilla2-dev  (thanks to Tatsuro)
            sudo apt-get install  libportaudio-dev  libqt4-opengl-dev (thanks to Chechu)

    o  CD into your Octave directory and execute
            ./configure
        Verify that you don't receive a "Qt libraries not found -- disabling GUI" message.

    o  Execute
             make
        This takes about two hours on my old PC

    o  Execute
              sudo make install
        This only takes a few minutes.

 (I'm not sure that libportaudio-dev is the correct library Octave needs in the third step, but having it seems to do no harm.)

Is there a better place than the maintainer's list to post this summary?  If so, it might save the next fellow a lot of time :-)

Regards,
Curt Carpenter

Good evening.
I miswrote the package name on my previous mail.
On ubuntu 14.04 Trusty it should be necessary to install :

libqt4-opengl-dev

Please try again the configure process after that install.
Yours sincerely Chechu
