Incompatible with OS X 10.10 Yosemite

Couldn't get this sucker to install on my Maverick's machine. When running rake compile, first I get can't find header dns_sd.h (which is present, in /usr/include):

If I remove that header check, I get:

Entirely borked, unfortunately. Not sure how to go about fixing here.

Mavericks or Yosemite?

Yosemite. I forgot I upgraded. Heh.

[sodabrew]

You're not the only one, that's good:
http://stackoverflow.com/questions/26824569/unable-to-find-dnssd-headers-error-while-trying-to-install-a-ruby-gem

Doesn't seem to have a new API, I wonder what's up.

[sodabrew]

@tenderlove Could you do a release from master branch? The last release was in 2011, and there's been a bunch of work since then in the repo. https://rubygems.org/gems/dnssd

Let's see if master compiles on Yosemite...

[drbrain]

You don't have a dns_sd.h? What files do you have in /usr/include?

$ mdfind -name dns_sd.h | grep -v /Users
/usr/include/dns_sd.h
$ ls -l /usr/include/dns_sd.h
-rw-r--r--  1 root  wheel  132596 Sep  9 13:50 /usr/include/dns_sd.h

[parkr]

@drbrain That's the weird part – I do:

~$ mdfind -name dns_sd.h | grep -v /Users
/usr/include/dns_sd.h
~$ ls -l /usr/include/dns_sd.h
-rw-r--r--  1 root  wheel  132596 Sep  9 13:50 /usr/include/dns_sd.h

master branch builds out of the box on Yosemite.

@sodabrew You're right. I think I figured out my problem – I am using a custom Ruby, a distribution by GitHub. When I switch to the system Ruby, it all goes as planned. I'll test with an rbenv'd unmodified MRI.

@drbrain Would you mind pushing out the latest changes?

[sodabrew]

@parkr Oh, I didn't figure on the custom Ruby being the issue. If you add --with-dnssd-dir=/usr does it work?

[parkr]

@parkr Oh, I didn't figure on the custom Ruby being the issue. If you add --with-dnssd-dir=/usr does it work?

Nope, tried that.

[drbrain]

I imagine github ruby uses a compiler and include path that you don't have access to?

The changes since v2.0 don't involve changes to mkmf.rb so I doubt they would make a difference. I note that in the compile log it says mkdir -p tmp/x86_64-darwin13.0/dnssd/2.1.2 which is attempting to use mavericks things.

Still, I can make a release as there are changes pending.

[parkr]

Must be it. Dammit. MRI 2.1.5 unmodified installs fine.

[drbrain]

2.0.1 released!

[parkr]

2.0.1 released!

❤️ You're the best, @drbrain.

Now to dig into where GitHub's Ruby differs from MRI... I definitely like their distro better.

Thanks guys!!

[sodabrew]

Thank you!
