Hi. In gcc version over 4.7 in libstdc++ remove unistd.h. Then build current last git version, get error:

[ 68%] Building CXX object mym/source/CMakeFiles/mym.dir/window.cpp.o
/media/data/games/emuls/gba/emuls/meteor/meteor-git/mym/source/window.cpp: In constructor ‘mym::Window::Window()’:

This path:

diff --git a/mym/source/window.cpp b/mym/source/window.cpp
index c58d461..556c987 100644

remove error and build successfull
