ebuild log file

When I wanted to upgrade octave it failed compiling and I checked the build.log for errors. I found several points that came to my attention.

I have an almost full install of the Qt5 framework, but only a limited set of Qt4 packages, which get pulled in from other packages installed. My default Qt implementation to use is therefore Qt5.

First the configure script doesn't look for Qt5 tools, but only for Qt4 and default. octave-3.8.2 did test for either (see bug #590532):

checking for QT... yes
checking for x86_64-pc-linux-gnu-moc-qt4... no
checking for x86_64-pc-linux-gnu-moc... no
checking for moc-qt4... no
checking for moc... moc
checking for x86_64-pc-linux-gnu-uic-qt4... no
checking for x86_64-pc-linux-gnu-uic... no
checking for uic-qt4... no
checking for uic... uic
checking for x86_64-pc-linux-gnu-rcc-qt4... no
checking for x86_64-pc-linux-gnu-rcc... no
checking for rcc-qt4... no
checking for rcc... rcc
checking for x86_64-pc-linux-gnu-lrelease-qt4... no
checking for x86_64-pc-linux-gnu-lrelease... no
checking for lrelease-qt4... no
checking for lrelease... lrelease

The configure script does not realize, the found lrelease does belong the Qt5 toolkit. I don't even have linguist:4 installed on my system and for Qt5 the lrelease belongs to linguist-tools, which isn't available for Qt4 anyway.

In the configuration summary it says to use the Qt4 framework:
  Qt CPPFLAGS:                 -I/usr/include/qt4 -I/usr/include/qt4/QtNetwork -I/usr/include/qt4 -I/usr/include/qt4/QtOpenGL -I/usr/include/qt4 -I/usr/include/qt4/QtGui -I/usr/include/qt4 -I/usr/include/qt4/QtCore 
  Qt LDFLAGS:                  -L/usr/lib64/qt4 
  Qt libraries:                -lQtNetwork -lQtOpenGL -lQtGui -lQtCore  -lqscintilla2

But it uses uic, which belongs to Qt5 to generate UI include files:
waebbl@artus ~/code $ uic -v
uic 5.6.1

and:
artus libgui # pwd
/var/tmp/portage/sci-mathematics/octave-4.0.2-r1/work/octave-4.0.2/libgui
artus libgui # head -n 4 src/ui-settings-dialog.h 
/********************************************************************************
** Form generated from reading UI file 'settings-dialog.ui'
**
** Created by: Qt User Interface Compiler version 5.6.1

Also the logfile says:
Making all in libgui
make[2]: Entering directory '/var/tmp/portage/sci-mathematics/octave-4.0.2-r1/work/octave-4.0.2/libgui'
uic -o src/ui-settings-dialog.h src/settings-dialog.ui

The settings-dialog.ui files says it's version 4:
artus libgui # head -n 2 src/settings-dialog.ui 
<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">

The compile then fails with the error:

This should rather be QtGui/QAction for the Qt4 framework.

Comment 1 Michael Palimaka (kensington) gentoo-dev

I don't know if octave actually supports Qt 5 or not, but in any case this sort of thing should be handled with a use flag rather than fiddling with qtchooser.

It also doesn't help the ebuild doesn't appear to specify *any* Qt dependencies at all.

Comment 2 Bernd 2016-08-08 16:00:42 UTC

I agree in that USE flags should be used to handle this. I changed the title to reflect this. Thanks for the hint.

The configure script shows no options for qt support, only two environment variables QT_CFLAGS and QT_LIBS are printed.

I found out, that the compile finishes by exporting QT_SELECT=qt4 prior to ebuild-ing octave. Haven't tested it with emerge though. Also exporting QT_SELECT=qt5 doesn't work, the configure script still shows the QT4 libraries and headers being selected, so it looks like QT5 isn't supported (yet).

Comment 3 Michael Hofmann 2016-08-21 17:24:50 UTC

Octave 4.0.x doesn't seem to work with Qt5. 

Some patches have been developed to make Octave work with Qt5. See comment #14 of  

   https://savannah.gnu.org/bugs/?40252

As far as I can see, these patches will be part of Octave 4.2.0.

Comment 4 David Seifert gentoo-dev

2016-11-21 07:39:46 UTC

Octave 4.2.0 has a USE="qt5" USE flag.
