I encountered a failure building wasm when using 'skia' renderer.
xb284524239 opened this issue · comments
I attempted to compile the MemoryTile demo into WASM, and two distinct scenarios emerged:
- When using the
femtovgrenderer, everything proceeded as expected. - However, when attempting to use the
skiarenderer, the build process failed.
My computer is Windows 10, and the Slint version is 1.7.1.

It appears that there was an attempt to download the file skia-binaries-e7e538647512cab844c3-wasm32-unknown-unknown-gl-textlayout.tar.gz from GitHub, which seems to have failed.
I then checked the repository at https://github.com/rust-skia/skia-binaries/releases/tag/0.75.0. Indeed, the file skia-binaries-e7e538647512cab844c3-wasm32-unknown-unknown-gl-textlayout.tar.gz is not present there.
A similar name I did find was for the binary file skia-binaries-e7e538647512cab844c3-wasm32-unknown-emscripten-gl-textlayout.tar.gz.
Perhaps this discrepancy is the reason why the compilation to wasm failed.
Slint can't be compiled for wasm32-unknown-unknown when the renderer-skia feature is enabled. You must use the renderer-femtovg feature for wasm builds.
I suppose we could do a compile_error!() in renderer-skia when targeting wasm. @ogoffart what do you think? (I can do it, but want to run it by you first)
I don't think we can do a compile_error easily, because the problem is already in the dependencies.
Ah indeed. Closing this issue as Skia can’t be built with wasm.
I think that you should report an issue with upstream. There's a possibility that in the future, the upstream might add support for wasm32-unknown-unknown in addition to wasm32-unknown-emscripten. If this were to happen, Slint would also benefit.
I think that would be rust-skia/rust-skia#982
