Hi,

facing error when running below command.

In the above error found "/rustc/90743e7298aca107ddaa0c202a4d3604e29bfeb6/library/core/src/sync/atomic.rs: No such file or directory".

Currently including rust-lang in gst-plugin-ndi. Is it enough to resolve this issue?

Please provide any suggestion on the above error.

I assume if you run cargo test in https://github.com/matklad/once_cell then you get the same?

Lokeshagit commented 1 year ago

Hello Sebastian,

Can you tell me what this once_cell does? because the error I got above was when i tried to execute gst-plugin-ndi using libndi 5.5.3.

So I want to understand if its issue with compatibility of libndi with gst-plugin-ndi or is it some RUST dependency of gst-plugin-ndi?

sdroege commented 1 year ago

There's documentation in the git repository about what it does. The question is whether that also crashes the same way.

Most likely you're using a wrong Rust toolchain for your CPU or there is a LLVM code generation bug.

Lokeshagit commented 1 year ago

We have used https://github.com/rust-embedded/meta-rust-bin to compile rustc and cargo.

And we have used gst-plugin-ndi to build for arm CPU for webOS using the built rustc from above
