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. $HOST = x86_64-unknown-linux-gnu $TARGET = x86_64-unknown-linux-gnu openssl-sys = 0.9.109 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`. warning: build failed, waiting for other jobs to finish...
