Build Failed: openssl-sys

[chrisabruce]

Not sure what I am doing wrong, but I can't get cross to work with openssl-sys crate.

I have tried both aarch64-unknown-linux-gnu and aarch64-unknown-linux-musl

Any suggestions?

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
and include information about your system as well as this message.

Ok catching up and now seeing Issue #229.

[chrisabruce]

Ok closing this issue as it seems that this project no longer wants to support openssl. For anyone that lands here, take a look at #229 and for a work around look at: #229 (comment)

Hopefully, there will be some longer-term ability to cross-compile projects that need openssl.

I also came across this problem when I tried to build for armv7. I used this guide as starting point and had to add libssl-dev libssl-dev:armhf to the apt install command. Before, I just installed libssl-dev which was not enough. Maybe this hint is useful for someone (in the future).

This is also documented on our wiki: https://github.com/cross-rs/cross/wiki/Recipes#openssl

Thanks for the hint, I did not find that page before.

For people trying to use the vendored way I ended with:

[dependencies]
...
openssl = { version = '*', features = ["vendored"] }

[build-dependencies]
openssl = { version = '*', features = ["vendored"] }
