error: could not compile `vortex-io` (lib) due to 4 previous errors
warning: build failed, waiting for other jobs to finish...
I think some system calls require linux
To Reproduce
Running command cargo build --release -p vortex-ffi
Expected behavior
Builds and gives me a .dll file i can use
Additional context
On windows 10.
This works on linux Arch and i get a .so file. But i cant get it to work on windows.
