Solution

Cloning https://github.com/sfackler/rust-openssl and running cargo build in its openssl-sys directory yields:

$ cargo build
   Compiling libc v0.2.21
   Compiling pkg-config v0.3.9
   Compiling gcc v0.3.45
   Compiling openssl-sys v0.9.10 (file:///home/christoph/repos/rust-openssl/openssl-sys)

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.

    $HOST = x86_64-unknown-linux-gnu
    $TARGET = x86_64-unknown-linux-gnu
    openssl-sys = 0.9.10


It looks like you're compiling on Linux and also targeting Linux. Currently this
requires the `pkg-config` utility to find OpenSSL but unfortunately `pkg-config`
could not be found. If you have OpenSSL installed you can likely fix this by
installing `pkg-config`.

So finally following helped:

$ sudo apt-get install pkg-config

I think this should be documented.

I didn't catch what is solution fort this issue ? Please, help

[c7hm4r]

You can try to install pkg-config (Ubuntu) or pkgconfig (Fedora)

[nickgonzales]

This solution did not work for me on Ubuntu 17.04. I already had pkg-config installed.

I had to also install:

• libssh-devel
• cmake

[c7hm4r]

@nickgonzales Note: rls can now be installed via rustup, see https://github.com/rust-lang-nursery/rls#setup

[discosultan]

If libssh-devel does not work, try libssh-dev.
