Hello,
Trying to build qt5 with debug symbols, but failed. Using the qt5 from
abs, per instructions in the wiki (
https://wiki.archlinux.org/index.php/Debug_-_Getting_Traces), I added in
the PKGBUILD
options=(debug !strip)
and added
-developer-build -no-warnings-are-errors
to the configure and build with and without qt5-webkit. Got following
messages:
I had a similar problem. For me, the following worked.
Use this configure command:
CXXFLAGS="-std=c++11" configure [all your configure options] -c++11
This forces the build system to use C++11, because by default C++98 is
used IIRC.
There is a compiler bug for c++98 (has_feature macros are defined but
the c++11 classes are not avaible) and I found a bugreport about it (for
gentoo), but the gcc developers said it's a downstream bug. Unfortunally
I can't find the bug report anymore :/
I hope this helps, David
