Do you mind sharing which linking error

It seems that the c++-dataflow demo is not supported on the Windows platform.

In c++-dataflow/run.rs, there's a code snippet that explicitly disables execution on Windows:

if cfg!(windows) { tracing::error!( "The c++ example does not work on Windows currently because of a linker error" ); return Ok(()); }

[haixuanTao]

ah ok. That's possible. I wonder if this is fixable

We never found the time to figure out the necessary linker flags for building on Windows. A pull request that removes this early-exit and adds the correct flags instead would be appreciated!
