Build QT project with CUDA caused pch error

[Miyoku]

Hi
I'm not an expert of qmake still I'm trying to use CUDA on QT. When I tried to run it with CUDA, it gives me an error for each QT libraries in my pch file:

error c1083 cannot open include file: 'QtWidgets/QOpenGLWidget' no such file or directory

Is there a link between my integration of CUDA and my pch file?

Here is my .pro file:

Do you have any ideas?

@Miyoku said in Build QT project with CUDA caused pch error:

'QtWidgets/QOpenGLWidget'

Remove QtWidgets from the include, it is enough to do

#include <QOpenGLWidget>
