mpd refuses to install

[bnhymn]

MPD refuses to install on my system. I've reinstalled Xcode and the developer tools to no avail. Full Log

Fails with this error:

Undefined symbols for architecture x86_64:
  "_allow_severity", referenced from:
      _severity_option in libwrap.a(options.o)
  "_deny_severity", referenced from:
      _severity_option in libwrap.a(options.o)
      _twist_option in libwrap.a(options.o)

If you build with --env=std does it work?

[bnhymn]

Unfortunately, no. Fails with exactly the same error.

Unrecognized option '--enable-zip' that's not a good start :-) A quick duck search tells me that allow_severity is a symbol from net-snmp or libwrap for tcpwrappers. My guess is something with libwrap. Here is what your log said:

checking for request_init in -lwrap... yes
configure: auto-detected libwrap

So at least we know it's being detected...

It just installed without error for me on 10.8.1 using XCode-4.4.1+CLT from Preferences.

Still not working for me — seems I'm out of date on OS X by x.x.1 but there's no update showing up in the App Store.

Hmm, and your XQuartz too. Strange. What's your brew list? And gist your /Users/bnhymn/Library/Logs/Homebrew/config.log if it still pertains to mpd.

[2bits]

On my system I just saw this:

configure: WARNING: libwrap not found -- disabling libwrap

So please see if you can find where that came from on your system.

I don't have /usr/lib/libwrap* after a clean install of Mountain Lion with XCode-4.4.1+CLT from Preferences. Did you upgrade from 10.7 or 10.6? What do you get for ls -l /usr/lib/libwrap.a? Somehow your config might be non-standard. What do you get for brew --config?

[bnhymn]

This install was upgraded from 10.7.

sudo mv /usr/lib/libwrap.a /usr/lib/libwrap.a.bak
brew install mpd
sudo mv /usr/lib/libwrap.a.bak /usr/lib/libwrap.a

Though I'm of the opinion that you can delete that library. It doesn't exist on my system nor in the 10.8 SDK as you've shown. ping @jacknagel to ask if disabling libwrap in mpd is reasonable.

[bnhymn]

Yep, that actually worked — I finally have a working install of mpd, thanks so much for that! I'll have to look into how libwrap.a got there.

[2bits]

I'll submit a PR to disable libwrap by default and make it an option to turn on. thanks

[jacknagel]

Sorry for ignoring this, I'm just now cleaning out my notifications.

On 10.6 I have /usr/lib/libwrap.{a, dylib}.

Presumably it is no longer part of OS X. Your solution sounds reasonable. Thanks.
