|
|
|
`ash-molten` is built on top of [ash](https://github.com/MaikKlein/ash) and exposes a new entry point to statically link with [MoltenVK](https://github.com/KhronosGroup/MoltenVK).
|
|
|
|
Requires Xcode 12 and Mac OS 10.15 (Catalina) to compile.
|
|
|
|
## Why?
|
|
|
|
* You want to compile down to a single binary that doesn't need any environment variables to bet set.
|
|
|
|
* You just want to try out [MoltenVK](https://github.com/KhronosGroup/MoltenVK) without needing to setup the SDK.
|
|
|
|
## Why not?
|
|
|
|
* [ash](https://github.com/MaikKlein/ash) already supports [MoltenVK](https://github.com/KhronosGroup/MoltenVK) via runtime linking. Runtime linking is the preferred way of using Vulkan because the loader can be updated at anytime without needing to recompile.
|
|
|
|
* `ash-molten` doesn't have access to the validation layers and therefore can not output any debug information.
|
|
|
|
## How?
|
|
|
|
```Rust
|
|
let entry = ash_molten::MoltenEntry::load().expect("Unable to load Molten");
|
|
let app_name = CString::new("Hello Static Molten").unwrap();
|
|
|
|
let appinfo = vk::ApplicationInfo::builder()
|
|
.application_name(&app_name)
|
|
.application_version(0)
|
|
.engine_name(&app_name)
|
|
.engine_version(0)
|
|
.api_version(vk_make_version!(1, 0, 0));
|
|
|
|
let create_info = vk::InstanceCreateInfo::builder().application_info(&appinfo);
|
|
let instance = entry.create_instance(&create_info, None).expect("Instance");
|
|
let devices = instance.enumerate_physical_devices();
|
|
println!("{:?}", devices);
|
|
```
|
|
|
|
You can run the example with `cargo run`.
|
|
|
|
## How does it work?
|
|
|
|
`ash-molten` links statically with [MoltenVK](https://github.com/KhronosGroup/MoltenVK), it then uses `vkGetInstanceProcAddr` to resolve all the function pointers at runtime.
|
|
|
|
### Features
|
|
|
|
`cargo build` will clone a specific release of [MoltenVK](https://github.com/KhronosGroup/MoltenVK) compile and statically link it with your application.
|
|
`cargo build --features pre-built` will download a pre-built version of MoltenVK from a release of ash-molten.
|
|
`cargo build --features external` provide own MoltenVK library.
|
|
|
|
If you want to compile [MoltenVK](https://github.com/KhronosGroup/MoltenVK) yourself, you can use the `external` feature. `cargo build --features external` requires `libMoltenVK` to be visible (`LD_LIBRARY_PATH`).
|
|
|
|
### How to update
|
|
|
|
To update the version of [MoltenVK](https://github.com/KhronosGroup/MoltenVK) uses, change the following:
|
|
|
|
- In `build.rs`, change `static VERSION = "1.1.0"` to the new [MoltenVK release](https://github.com/KhronosGroup/MoltenVK/releases) tag name
|
|
- Update the crate version in `Cargo.toml`
|
|
- Bump the patch version
|
|
- Set the version metadata to the MoltenVK release.
|
|
- E.g. `0.2.0+1.1.9` -> `0.2.1+1.1.10`.
|
|
- Before you can submit the PR, you must also update the prebuilt version. See the next section.
|
|
|
|
### Updating pre-built version
|
|
|
|
To update the prebuilt version of MoltenVK that ash-molten uses, change the following:
|
|
|
|
- Follow the steps mentioned above.
|
|
- Download the MoltenVK XCFramework from, for example, the Vulkan SDK for Mac or build [MoltenVK](https://github.com/KhronosGroup/MoltenVK/) yourself.
|
|
- in the case of downloading it from an external source make sure MoltenVK version matches `static VERSION`.
|
|
- From the XCFramework folder, from the built version of MoltenVK, zip the folders of platforms that need to be supported individually.
|
|
- Create a release with the tag: MoltenVK-{version number}.
|
|
- Upload the zip files to the release with the MoltenVK-{version number} tag.
