# Magnum + Qt Quick bootstrap
|
||
|
|
|
||
|
|
This app demonstrates Magnum rendering engine within a Qt Quick application, using
|
||
|
|
a shared framebuffer object..
|
||
|
|
|
||
|
|
## Common pitfalls
|
||
|
|
|
||
|
|
### Header inclusion order
|
||
|
|
|
||
|
|
Follow one simple rule: Always include Magnum's headers first. If you're including
|
||
|
|
your own headers, make sure that this rules is obeyed. It's very easy to violate it.
|
||
|
|
|
||
|
|
Common symptom is compiler errors about missing declarations for `glFinish`, `glFlush`
|
||
|
|
and `glGetError`, which some Qt headers (`QOpenGLFunctions`) are undefining.
|
||
|
|
|
||
|
|
For a bomb-proof solution, make a header file that includes all of your Magnum and Qt
|
||
|
|
dependencies in correct order.
|
||
|
|
|
||
|
|
### CMake AUTOMOC
|
||
|
|
|
||
|
|
CMake detects a Qt project and enables `moc` preprocessor automatically for certain
|
||
|
|
source files. This may not play well with Magnum's headers. If you see `moc` related
|
||
|
|
build errors in Magnum's headers, improve separation between Magnum and Qt code, ie.
|
||
|
|
move Magnum code to its own source files.
