minitube $ grep -i qtsingleapplication *.pro include(src/qtsingleapplication/qtsingleapplication.pri)
Is there a way for the package to support the system library? Otherwise we may have to patch it (who?) and upstream is not very friendly with non-ubuntu-ish distributions.
You need to patch build system, example: https://code.google.com/p/quite-rss/source/detail?r=eb1892cbe9a0 Also you need to check if internal copy of qtsingleapplication is patched.
I am not very keen in patching the build system. would you like to move this discussion upstream so they can do it properly?
Created attachment 388460 [details, diff] patch to ebuild to make minitube use system-wide qtsingleapplication Here is patch fixing the issue. I've tried it removing src/qtsingleapplication, compiling minitube then and successfully running it.
