missing protobuf-compiler

[vonnull]

Hello,

I've installed nostr on a fresh PC.

error: failed to run custom build command for nostr-rs-relay v0.8.9 (/opt/nostr-rs-relay)

Caused by:
process didn't exit successfully: /opt/nostr-rs-relay/target/release/build/nostr-rs-relay-47635d6023da92ab/build-script-build (exit status: 101)
--- stdout
cargo:rerun-if-changed=proto/nauthz.proto

--- stderr
thread 'main' panicked at 'Could not find protoc installation and this build crate cannot proceed without
this knowledge. If protoc is installed and this crate had trouble finding
it, you can set the PROTOC environment variable with the specific path to your
installed protoc binary.If you're on debian, try apt-get install protobuf-compiler or download it from https://github.com/protocolbuffers/protobuf/releases

After i did "apt-get install protobuf-compiler" compiling worked. Please add protobuf-compiler to install dependencies.

Thank you

I'm running Ubuntu 24.04 on a Digital Ocean droplet, ran into the same problem and solved it (before I saw this issue had been opened) using
apt install -y protobuf-compiler libprotobuf-dev
as per recommendations here:
grpc/grpc-rust#1047
