OpenSSL crate fails compilation on Mac OS X 10.11

Question

I tried to install the Iron framework for Rust on Mac OS X 10.11.2, but it failed when I run cargo build or cargo run on compiling openssl

Answer 1

With Brew use like this:

brew install openssl
export OPENSSL_INCLUDE_DIR=`brew --prefix openssl`/include
export OPENSSL_LIB_DIR=`brew --prefix openssl`/lib
cargo clean
cargo build
