2.8.0 In rion overlay now. Please test.

[Comment 2 Egor Y. Egorov 2015-02-24 09:43:25 UTC]

Can you show full output of
qlist qwt && emerge -pv qwt:5 qwt:6
and full build.log

[Comment 3 Egor Y. Egorov 2015-02-24 09:56:23 UTC]

and emerge -pv x11-libs/qwtpolar

[Comment 4 Martin von Gagern 2015-02-24 12:19:44 UTC]

This appears to be due to portage preserving libs. I have libqwt6.so.6 preserved by portage, while libqwt6.so isn't preserved. Adding that symlink I was able to emerge qgis, but the new qgis version will still depend on the old library.

I realize that I'm using a qgis ebuild from my own overlay, probably imported from rion at some point. I do whish we'd get bug 485868 addressed, i.e. a recent qgis included in the main portage tree.

I'll need to rebuild layman with mercurial support before I can give the rion overlay a try. Will report back after that.

Same problem: No rule to make target '/usr/lib64/libqwt6.so', needed by 'output/lib64/libqgis_gui.so.2.8.0'.  Stop.

Perhaps gdal should be using pkg-config?
# pkg-config --libs qwt6
-L/usr/lib64/qt4 -lqwt6-qt4 -lQtSvg -lQtOpenGL -lQtGui -lQtCore 

The current search looks like this:
FIND_LIBRARY(QWT_LIBRARY NAMES qwt qwt5 qwt6 qwt-qt4 qwt5-qt4 PATHS
So it likely won't find qwt6-qt4 even if there is no qwt6 to distract it.

[Comment 6 Egor Y. Egorov 2015-02-25 05:38:35 UTC]

Ok. this is because >=qwt-6.1.2 have IUSE="qt4 qt5" and ebuild change name of this libs adding suffix -qt4 or -qt5 correspondingly.
Using pkg-config in this case look logically. But I do not know how this make perfectly. I pushed ebuild with workaround in rion-overlay. Now qgis must built fine with any qwt in portage. Please test.

Compiles and launches. Looks good to me.

Version is not in tree and I didn't even find it in rion-overlay
