I am not sure why qmake-qt5 doesn't want to trust gcc for the system include dirs, but well.. it doesn't. I reduced the problem down to this. Consider the following program: #include <algorithm> int main(){} This compiles fine with both gcc5 and 6 with g++ -c inctest.cpp -o inctest.o On the other hand, it compiles fine with gcc5, but fails with gcc6 if the compiler is invoked liked this: g++ -c -isystem /usr/include inctest.cpp -o inctest.o The failure message is /usr/include/c++/6.0.0/cstdlib:75:25: fatal error: stdlib.h: No such file or directory I am not sure what is the expected behavior. Maybe people familiar with gcc can shed some light. I noticed the difference: In cstdlib, the gcc5 line 75 #include <stdlib.h> became in gcc6: #include_next <stdlib.h> Thanks, Orcan -- devel mailing list devel@lists.fedoraproject.org http://lists.fedoraproject.org/admin/lists/devel@lists.fedoraproject.org
