Description Kris Scott 2017-10-17 05:10:28 UTC

when net-p2p/qbittorrent is compiled against libtorrent-rasterbar-1.1.x, it requires libtorrent to be compiled with the -std=c++11 flag. Please either add this as a use flag or as the default.

See qbittorrent upstream bug here: https://github.com/qbittorrent/qBittorrent/issues/5265

Thanks for your report, fixed in git commit b1f7321677c90120e3d079f980aa8dc9f9a804bd.

Unfortunately this solution conflicts with code that uses libtorrent and is built with C++14 or newer. Long story short, if the client code is using C++ ≥14, then libtorrent should also be built with C++14 (or newer), otherwise it should be C++11.

I could see two solutions off the top of my head:
1. Add a use flag (meaning packages using libtorrent and built with different C++ standards will conflict).
2. Patch libtorrent source to avoid this dependency.

How do you reckon?
