• Status: RESOLVED FIXED

Building net-p2p/qbittorrent-3.3.4-r1 with gcc-6 fails with:

> In file included from /usr/lib/gcc/x86_64-pc-linux-gnu/6.1.0/include/g++-v6/bits/stl_algo.h:59:0,

GCC-6 will fail to build with "-isystem /usr/include" (see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70129).

According to https://bugreports.qt.io/browse/QTBUG-53367 it is the responsibility of maintainers using qmake in their packages to properly filter '/usr/include' from INCLUDEPATH:

"the problem are the broken qmake-based build systems of 3rd party applications, which somehow end up adding /usr/include to INCLUDEPATH. report bugs against these applications."


I submitted a pull request with qbittorrent upstream pending approval:

is this fixed in 3.3.7?

[Comment 5 matt black 2017-01-23 05:11:15 UTC]

Version 3.3.7 builds successfully for me with gcc-6.3.0 on amd64
