Building the mongo_driver crate fails to link on macOS:

Linking the Security and CoreFoundation frameworks appears to resolve the linking issues.

Looks like this broke in Sierra, a fully clean compile does not work on my Mac anymore either.

The error on my machine is:

Upgrading the C driver in #21 did not fix it.

thijsc commented 7 years ago

These instructions fixed it for me:

brew install openssl
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"

I've added a note about this to the readme: 08ef8fbf2b94bb93d0f5e36e310a895d8539695c

Currently I don't see good options to make this smoother, so closing the issue.

@thijsc I've noticed that when pkg-config is installed on macOS, CPPFLAGS and LDFLAGS do not have effect, as the configure script tries to use pkg-config to detect OpenSSL and fails to do it because pkg-config package for OpenSSL is not configured by Homebrew. Once I've uninstalled pkg-config, the instructions with LDFLAGS and CPPFLAGS worked for me. It might be worth to mention this behavior in README.
