Hello, I'm getting the same issue with the "vite" package now that I have migrated it from qt4 to qt5:
https://buildd.debian.org/status/fetch.php?pkg=vite&arch=armel&ver=1.2%2Bsvn1430-5&stamp=1450824398 In file included from /usr/include/arm-linux-gnueabi/qt5/QtGui/qopengl.h:97:0, from /usr/include/arm-linux-gnueabi/qt5/QtOpenGL/qgl.h:39, from /usr/include/arm-linux-gnueabi/qt5/QtOpenGL/QGLWidget:1, from /«BUILDDIR»/vite-1.2+svn1430/src/render/Render_opengl.hpp:56, from /«BUILDDIR»/vite-1.2+svn1430/src/render/Render_opengl.cpp:67: /usr/include/GLES3/gl3.h:69:25: error: conflicting declaration 'typedef khronos_ssize_t GLsizeiptr' typedef khronos_ssize_t GLsizeiptr; In file included from /usr/include/GL/gl.h:2055:0, from /usr/include/GL/glu.h:38, from /«BUILDDIR»/vite-1.2+svn1430/src/render/Render_opengl.cpp:52: /usr/include/GL/glext.h:468:19: note: previous declaration as 'typedef ptrdiff_t GLsizeiptr' typedef ptrdiff_t GLsizeiptr; vite just happens to be using both QGLWidget and GL.
