If /usr/local/include wo= uld ever be put into the default include path, it should be put *after* the sys= tem include directories, not before. But the bikeshedding about this subject has been going on forever, it is ve= ry hard to please everybody now, so keeping the status quo is the safest solut= ion. :) > $ cat a.cc > #include > int main() { return 0; } > $ c++ a.cc -isystem/usr/local/include > $ c++ a.cc -I/usr/local/include > In file included from a.cc:1: > /usr/local/include/X11/Xlibint.h:675:7: warning: 'register' storage cla= ss > specifier is deprecated and > incompatible with C++17 [-Wdeprecated-register] > register _Xconst long *data, > ^~~~~~~~~ > [...] >=20 > - Clang 6+ defaults to C++14, so -Wdeprecated-register isn't an error yet= but > Qt5 passes -std=3Dc++1z Yeah, I have not found out why Qt seems to insist on very high -std=3Dc++ versions. It probably attempts to auto-detect the highest level supported = by the compiler, and always enables that. > - GCC 7 + -std=3Dgnu++17 doesn't treat -Wregister as an error by default It should, because register is finally going away with C++17.
