# The headersclean test attempts to ensure all public Qt headers
# abide by various rules.
#
# To use this test, create a project which contains nothing else than a
# QT= line with the modules you want to test (no presence conditionals needed),
# followed by load(qt_headersclean).

*-g++*: QMAKE_CXXFLAGS += -W -Wall -Wextra -Werror

# The flags here come from http://wiki.qt-project.org/Coding_Conventions#Conventions_for_public_header_files
# -Wold-style-cast cannot be used, /usr/include/bits/byteswap.h defines the macro bswap_16 using C style casts :(
# -Wfloat-equal cannot be used, qrect.h and qvector2d.h do exact comparisons in isNull and operator==. Would need #pragmas.
*-g++*: QMAKE_CXXFLAGS += -Woverloaded-virtual -Wshadow -Wundef
