Whenever I try to compile I get

I have both OpenSSL and OpenSSL-1.0 installed. I have tried using both Rust stable and nightly. I've also tried to include different versions of the openssl crate, but I think Cargo is just building the version of the crate that I think grpc is using. I'm on Arch Linux.

Welcome to Stack Overflow! Please review how to create a minimal reproducible example and then edit your question to include it. We cannot tell what code you are even attempting to compile. You can reproduce it in a brand new Cargo project. There are Rust-specific MCVE tips as well. — Shepmaster

Your project is using openssl 0.9.x (probably via tls-api-native-tls 0.1.x -> native-tls 0.1.x -> openssl 0.9.x), which doesn't support OpenSSL 1.1.1. I'm also on Arch Linux and I've had to update my programs to openssl 0.10 in order to use OpenSSL 1.1.1.

In your case, tls-api-native-tls needs to be updated to depend on native-tls 0.2.x, which uses openssl 0.10.x (which does support OpenSSL 1.1.1). There is an open issue about this.

If that's too complicated, you can also use various environment variables to tell openssl-sys's build script which installation of OpenSSL you'd like to use. If you'd prefer using OpenSSL 1.0.x, enter the following commands in your shell:

$ cargo clean
$ OPENSSL_INCLUDE_DIR=/usr/include/openssl-1.0 OPENSSL_LIB_DIR=/usr/lib/openssl-1.0 cargo build

(Note: the paths above may be specific to Arch Linux.)

For more information on the environment variables you can use to configure openssl-sys, see Manual configuration.
