OpenSSL build issue on OS X

help

I'm running a program that accesses the Iron crate and I'm having build issues with openssl:

λ ~/rust/workspace/iron-gcd/ master* cargo build
   Compiling openssl-sys-extras v0.7.13

I saw that there were issues with Windows and Iron but I'm having a similar problem with OS X. I'm using the latest stable build of Xcode and tools and shown at the end with gcc -v information.

Has anyone else run into this issue lately?

There are instructions in the rust-openssl README file for installing the required OpenSSL headers on Mac OS X.

Depending on your requirements, you may want to consider installing open-ssl directly from brew. This will get you the actual open-ssl rather than Apple's take.

Yup that did it. Now I just need to make sure those environment variables are exported under eshell. But I'm pretty sure I got that covered.

Thanks @mbrubeck!

Of course, now I have other issues but it appears that the example that I'm following has an issue with bodyparser. Time to dig into that one.
