Bug 588994 – sci-geosciences/qgis-2.12.2 and dev-python/sip-4.18: error: request for member ‘insert’ in ‘qm’, which is of pointer type ‘QMap<long long int, QMap<int, QVariant> >*’

After upgrading grass, I failed to re-merge my qgis-2.12.2. The most likely difference to the previous successful run is that now I have sip-4.18 installed, where I had 4.17-r1 before.

?)

https://github.com/qgis/QGIS/commit/fc6559aa053317cda8ced657c3013a0d4c6549e9 deals with this issue upstream. According to its commit message, the code in question never actually worked. The preprocessor switches were meant for sip 4.12 but due to a hex conversion error targeted 4.18 by accident. So until this is fixed in the ebuild, I'd suggest the following solution:

mkdir -p /etc/portage/patches/sci-geosciences/qgis-2.12.2
cd /etc/portage/patches/sci-geosciences/qgis-2.12.2
wget https://github.com/qgis/QGIS/commit/fc6559aa053317cda8ced657c3013a0d.patch
emerge -1 =sci-geosciences/qgis-2.12.2

Thanks for the detective work. I can confirm that suggested solution, eg. using the patch works for my setup as well:

I can confirm. Patch works also for Sabayon: https://github.com/Sabayon/for-gentoo/tree/master/sci-geosciences/qgis

Thanks for the report. A version which contains the fix is now in tree:
