Post by: wmbuRn on August 15, 2013, 03:07:28 am

http://pastebin.com/SYvGB6N5  << entire build log.

Actual warning is on 36%

[ 36%] Building CXX object src/SFML/Window/CMakeFiles/sfml-window.dir/Linux/JoystickImpl.cpp.o
/home/xwm/Downloads/SFML-2.1/src/SFML/Window/Linux/JoystickImpl.cpp: In static member function ‘static bool sf::priv::JoystickImpl::isConnected(unsigned int)’:
/home/xwm/Downloads/SFML-2.1/src/SFML/Window/Linux/JoystickImpl.cpp:123:51: warning: ignoring return value of ‘ssize_t read(int, void*, size_t)’, declared with attribute warn_unused_result [-Wunused-result]

There's nothing wrong with that warning. That's just there because Laurent decided not to use the return value from the mentioned function for anything.
