Doing a manual
capnp-rust compile -orust:out --src-prefix=. addressbook.capnp
where capnp-rust is the bin compile from this crate, just never terminates. Am I doing something wrong?
Do I need the capnp binary from the website, to compule the scheme files?
Got it,the Cap'n Proto scheme file compile has to be installed from https://capnproto.org/install.html.
Could you please document this somewhere?
Hi! Thanks for reporting this.
The error ought to display a message pointing you to https://capnproto.org/install.html . In your case, it looks like somehow this call to command.spawn() succeeds, even though the capnp executable is not installed on your system. I'm interested in figuring out how that could happen. What operating system are you on?
The solution is probably to bubble that map_err() call out a bit, so that it would have caught the error in your case.
This is on Debian 8 using Rust nightly.
