Can't build OpenSSL-dependent crates
Opened this issue · 3 comments
Hey all,
I used to be able to build a project that uses crates like hyper which depend on OpenSSL (and a C compiler) with remote compilation (Aug 14th, at least). After upgrading to the newer versions of the CLI, this fails when trying to invoke the compiler:

This can be repro'd with:
mkdir tesselrepro && cd tesselrepro
t2 init --lang=rust
echo "hyper = \"0.9.x\"" >> Cargo.toml
t2 run blinky --rustcc
This likely blocks #56.
Bump - has Tessel been abandoned? The last commit was October last year.
I'm honestly a little disappointed - I bought Tessel 1's and had hoped to use them with SSL-secured endpoints. That didn't pan out, and I was told T2 would address the issue. So, I bought a bunch of T2s, and I'm met with essentially the same end result. I'm disappointed because T2 really does seem like a much nicer board than competition, but this is a table-stakes feature.
From the error message, the failure is when it is trying to link the build script for the openssl-sys crate. The build script runs on the host architecture, but the build server doesn't have a native C compiler installed, so Rust can't link binaries that run on the host.
You should open an issue on https://github.com/tessel/rust-compilation-server, or submit a PR there to apt-get install build-essential in its Dockerfile.
Err, it theoretically has gcc. Maybe an issue with $PATH, or something else making it unable to find cc.
