Build fail

[exvx]

I get the same message when running cargo install amp and cargo build --release from the cloned repo. It prints Could not find directory of OpenSSL installation, even though openssl is installed.

Here's the full error message:

error: failed to run custom build command for `openssl-sys v0.9.27`
process didn't exit successfully: `/tmp/cargo-install.yJ1wLyvtL0b7/release/build/openssl-sys-7b6643d0518785c1/build-script-build` (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.

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.

My own incompetence could be the cause. I'd appreciate any help.

Edit Some more information: I'm running a fresh install of Ubuntu 17.10. I've installed amp a couple times on different machines, and I've built it as well when that didn't work, but this is the first time I get the same error message for both installing and building.

sudo apt remove openssl && sudo apt install openssl somehow fixed it. My openssl install was probably in a weird place. I apologize if this shouldn't have been an issue.

Glad you got this sorted! 🙂
