Bug 641258 – sci-geosciences/qgis-2.18.14 fails to resolve dependecies

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Vincent-Xavier JUMEL 2017-12-16 09:34:44 UTC]

sci-geosciences/qgis-2.18.14::gentoo seems to need
x11-libs/qwtpolar-1.1.1-r1::gentoo with +Qt4 flag, but QT4 has reached EOL

https://htmlpreview.github.io/?https://raw.github.com/qgis/QGIS/master/doc/INSTALL.html
indicate it's possible to compile the master branch with qt5.

https://htmlpreview.github.io/?https://raw.github.com/qgis/QGIS/release-2_18/doc/INSTALL.html
indicate the 2.18 series is meant to be compiled with qt4

What is this bug about, exactly?

- Fix your qwtpolar USE flags (+qt4 -qt5) - not a bug.
- qgis future bump bug exists - bug 635798

About this :
> These are the packages that would be merged, in order:
> 
> Calculating dependencies... done!
> 
> emerge: there are no ebuilds built with USE flags to satisfy ">=x11-libs/qwtpolar-1[qt4(-)]".
> !!! One of the following packages is required to complete your request:
> - x11-libs/qwtpolar-1.1.1-r1::gentoo (Change USE: +qt4, this change violates use flag constraints defined by x11-libs/qwtpolar-1.1.1-r1: 'exactly-one-of ( qt4 qt5 )')
> (dependency required by "sci-geosciences/qgis)

As I already wrote above ^ that's not a bug, just set it straight (in /etc/portage/package.use).

And see also bug 633650 about why there is no currently good solution for qwtpolar.
