Vulkan support

[happydpc]

Will vulkan api be supported in the future?

Are you referring to the Vulkan API provided by Qt? It's possible to add it. It's not included by default because #include <QtGui> doesn't include Vulkan related API (presumably because it requires that Vulkan headers are installed in the system). We can probably make it a separate crate.

Qt's Vulkan API uses subclassing a lot, and ritual doesn't support subclassing yet. So we'll need to work on that to make Vulkan API fully usable.

Yes, I want to embed vulkan view on Qt widget. And another question is ritual on windows seems still not work, because of the -PIC.

CI shows that ritual should work on Windows with MSVC 2017, but other compilers are untested yet. Can you describe your environment (OS version, rust toolchain, C++ compiler version, Qt version and Qt build's target compiler) where ritual doesn't work?

Ok, I will try again. The generating process may cost too much time. And I love this project. it works very well on linux.

I am using windows 10, rust-1.40.0-nightly. MSVC2017 , Qt 5.13.1, build for msvc 2017. I have found the problem, it's the problem of cpp_checker, at tmp\cpp_checker\tests\src\main.cpp:

#include "utils.h"

int main() {
{
}
}
}

this will triger the compile error with no return value.

Still the same error:

This link may help, google/shaderc#772.

The -fPIC related error on Windows should be fixed now.

The -fPIC related error on Windows should be fixed now.

Thank you for all your efforts. I am going to have a try.
