cc1plus: warnings being treated as errors
/usr/include/qt4/QtCore/qstring.h: In function 'QDateTime
Jabber::stamp2date(const std::string&)':
/usr/include/qt4/QtCore/qstring.h:701: error: assuming signed overflow
does not occur when assuming that (X - c) > X is always false

со всего что присутствует:

%define cmake_flags -DPREFIX=%prefix -DCMAKE_INSTALL_PREFIX=%prefix

%build
CFLAGS="%optflags" \
CXXFLAGS="%optflags" \
cmake %cmake_flags .
%make_build
