Compilation failure, OS X

[blt]

Kushal Pisavadia has reported on twitter that he's having trouble compiling cernan. Twitter's too wee to get much information so I'm creating this tracking issue to solicit detailed compilation failures.

For the sake of completeness, the Twitter thread that @blt refers to above is here: https://twitter.com/KushalP/status/820995772825174022

The below is split into the build failure I get with the ring dependency and details about my environment.

Boy, I really don't have a good idea. I'm on basically the same system and the above works for me and those are the instructions that made it into the wiki.

The ring dep is coming in through rusuto. There's already a ticket to enable feature flags #177 for lua. One cheating way to "fix" this is to put rusuto behind a similar flag, removing the dep.

[blt]

@KushalP I've created a branch and a PR here that updates ring to the latest version. Can you try rebuilding that branch please?

[KushalP]

Upgrading the dependencies appears to throw the same error. I'm going to pick apart my environment, includes, compiler, etc. tomorrow when I get some time.

[blt]

@KushalP bummer. :<

I'll try and set up a blank OS X and see if I can't reproduce.

I had different problem with ssl:

cargo:warning=src/openssl_shim.c:1:10: fatal error: 'openssl/hmac.h' file not found
cargo:warning=#include <openssl/hmac.h>
cargo:warning=         ^
cargo:warning=1 error generated.

And I fixed it with:

$ export C_INCLUDE_PATH=/usr/local/opt/openssl/include

Could you try if it helps?

[blt]

I believe this is now fixed, at least in so far as OpenSSL on OSX is always painful.
