It is, if the compiler works. > Right now, I'm having building errors like: > ---------------------------------------------------------------------------- > -------------- ... > /usr/bin/clang++ -m64 -g -O0 -Wall -Wextra -pipe -fexceptions > -fvisibility=default -std=c++11 -stdlib=libstdc++ -fPIC [...] > ... > In file included from > /home/krys/Qt5.7.0/5.7/gcc_64/include/QtCore/qbytearray.h:52: > /usr/include/c++/v1/string:1938:44: error: 'basic_string<_CharT, > _Traits, _Allocator>' is missing exception specification > 'noexcept(is_nothrow_copy_constructible<allocator_type>::value)' > basic_string<_CharT, _Traits, _Allocator>::basic_string(const > allocator_type& __a) The error is inside a file that is not part of Qt. That's not our problem. Please fix your compiler and/or the file in question. Also note how the file is in /usr/include/c++/v1 (libc++), even if your clang command-line says -stdlib=libstdc++. Something is really wrong with your compiler (assuming the [...] didn't hide anything important). > I'm not sure if this is a Ubuntu 16.04 bug, a Qt bug or if simply this > kind of build is simply not supported. It is. I compile Qt with Clang on Linux about once a month. I only test the current version and the upcoming one (respectively right now, 3.8 and 3.9). My recommendation is that if you're going to opt for a non- standard compiler that is known to produce slightly worse code than the default, you should make sure you're using something no more than a year old. I will not help with anything older than Clang 3.8 right now. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
