Current HEAD won't install on OSX 10.11.6 (though 0.1.4 does build)

[telemachus]

I usually follow HEAD, but when I tried updating today, it failed as follows. (I can install 0.1.4 fine.)

This was fixed the other day, and it doesn't look like you've updated. Try running brew update and installing again.

[telemachus]

@jszakmeister I don't think that can be the whole story. I had updated recently, but to be sure, I ran brew update again and then tried the install again. It failed in exactly the same way.

However, I can see that I hadn't gotten this patch in my version of the neovim formula. I untapped and retapped the formula, and I'm trying again now.

[jszakmeister]

See #175 and #176. And if you were update-to-date, I'd expect to see -DUSE_BUNDLED_GPERF=OFF before -DUSE_BUNDLED_LUV=OFF in this part of what you pasted:

==> Building third-party dependencies.
==> cmake ../third-party -DUSE_BUNDLED_BUSTED=OFF -DUSE_BUNDLED_LUV=OFF -DUSE_EX

[telemachus]

@jszakmeister Yes, sorry, we just missed each other. I saw one of those issues, and I'm trying again now. I can't figure out why brew update told me I was up to date and didn't update the tap though.

As you thought: with the updated tap, it was fine. Thank you for your help. Now I just need to figure out why brew up wasn't working as it should.

[jszakmeister]

Perhaps you have local edits to the formula? I could see that keeping it from being up-to-date.

[jszakmeister]

As you thought: with the updated tap, it was fine. Thank you for your help. Now I just need to figure out why brew up wasn't working as it should.

That's unfortunate that you had to do that, but I'm glad it's working for you now!

[telemachus]

I don't believe I edited the formula locally. In any case, thanks. I'll check if something is wrong with my Homebrew installation.

[telemachus]

@jszakmeister I had a case of this:

If Homebrew was updated on Aug 10-11th 2016 and brew update always says Already up-to-date. you need to run: cd $(brew --repo) && git fetch && git reset --hard origin/master && brew update.

I found that when I went to file an issue at brew itself. I'm putting this here to save people a step if anyone else comes here with a similar set of problems. (E.g., "I upgraded ten times, but I don't see your fixed formula...")

[jszakmeister]

Ugh, that stinks. Thanks for the heads up!
