Comment 1 Nikos Chantziaras 2020-08-29 08:11:19 UTC 
And trying to run qbittorrent if it was already built with libtorrent-rasterbar-1.2.8 results in an abort:

Comment 2 wbrana 2020-08-29 14:57:41 UTC 
something is probably compiled with wrong -std= value
Comment 3 Jouni Kosonen 2020-08-29 23:27:04 UTC 
(In reply to wbrana from comment #2)
> something is probably compiled with wrong -std= value

Yes, looks like using autotools adds -std=c++11 to the command line by default but clients compiled with c++14 using version 1.2.9 of the library then need some additional compilation flag to have access to that ABI.
Comment 4 Vladimir Smirnov 2020-08-30 00:02:56 UTC 
It seems that autotools configuration is deprecated in favor of CMake as if you just switch to cmake - it will work fine without any problems. However I struggle to find exact commit that cuases the problem here as there were numerous that introduced new CMake flags related to C++11/14 ABI but none of those touched autotools build system.

Any reasons why Gentoo still goes for autotools instead of CMake for this package?
