Building with 'hyper-rustls' feature and without 'native-tls' still requires openssl-sys crate.

[prixt]

I'm trying to cross-compile an application from Windows to the Pi(armv7-unknown-linux-gnueabihf).
It seems egg_mode still uses the openssl-sys crate, and therefore requires linking to OpenSSL binaries/libs.

In Cargo.toml:
egg_mode={version="0.13.0", default-features=false, features=["hyper-rustls"]}

Command:
cargo build --release --target=armv7-unknown-linux-gnueabihf

Result:

error: failed to run custom build command for `openssl-sys v0.9.49`                                                        

Caused by:
  process didn't exit successfully: `D:\MyProjects\Rust\twitter_bot01\target\release\build\openssl-sys-a844bd1d65ed445b\build-script-main` (exit code: 101)

Could not find directory of OpenSSL installation, and this `-sys` crate cannot
proceed without this knowledge. If OpenSSL is installed and this crate had
trouble finding it,  you can set the `OPENSSL_DIR` environment variable for the
compilation process.

Make sure you also have the development packages of openssl installed.
For example, `libssl-dev` on Ubuntu or `openssl-devel` on Fedora.

If you're in a situation where you think the directory *should* be found
automatically, please open a bug at https://github.com/sfackler/rust-openssl

It seems this is a problem when you get 'egg-mode' using crates.io & cargo. After I cloned this repository and built this crate locally with the same features, it builds just fine...

# egg-mode = {version="0.13.0", default-features=false, features=[ "hyper-rustls" ]} # This doens't work.
egg-mode = {path="twitter-rs", default-features=false, features=[ "hyper-rustls" ]} # But this does?

Where is the problem here?

I don't think there is a 'problem' as such. The bug you hit has been fixed in master but not yet released. You can use master until the next release is ready.

Didn't know master was newer than the cargo version. Cargo.toml version was the same. Closing this issue then.
