make: don't know how to make ./src/rust/target/release/libtor_rust.a
I'm trying to add the option to build tor with Rust to pkgsrc. On NetBSD 9 (8.99.48) amd64, this fails at the moment:
CC src/trunnel/libor_trunnel_a-socks5.oCC src/trunnel/libor_trunnel_a-netinfo.oCC src/trunnel/libor_trunnel_a-circpad_negotiation.oAR src/trunnel/libor-trunnel.aCC src/lib/trace/trace.oAR src/lib/libtor-trace.a
make: don't know how to make ./src/rust/target/release/libtor_rust.a. Stop
make: stopped in /usr/work/pkgsrc-ng0/tor/work/tor-0.4.0.5 *** Error code 2
Stop. make: stopped in /usr/work/pkgsrc-ng0/tor/work/tor-0.4.0.5 *** Error code 1
Stop. make: stopped in /usr/pkgsrc/pkgsrc-ng0/tor *** Error code 1
Stop. make: stopped in /usr/pkgsrc/pkgsrc-ng0/tor
rust and cargo are available in the build environment, and the crates are made available ahead of time and TOR_RUST_DEPENDENCIES points to the directory they are in.
Questions: to verify if I hit an error on tor's side or Rust specifics wrt NetBSD, and not on my side, do you support verbose builds? If you have seen this kind of error before in to on other platforms, was there a resolution (I have seen 3 vaguely similar tickets).
Disclaimer: I'm a contributor to pkgsrc, but I'm not the pkgsrc maintainer for tor, so this is more of a personal exploration to see if I can propose it.
