Build fails with Homebrew: no matching member function for call to 'next'

[mhartington]

Hi there! So I know macOS 10.12 is still in beta and not publicly out, but I thought I'd give you a heads up!

Trying to install via homebrew fails to build

$ brew install neovim-dot-app

Now, I'm not sure if this is an error related to you, msgpack, or scons, but thought I'd bring it to your attention.

let me know if you need anymore information.

Cheers!

Try

brew install --HEAD neovim-dot-app

[mhartington]

Hmm, that seems to introduce even more interesting problems.

The window controls are there, but nothing else.

[bambu]

Try defaults delete uk.foon.neovim and reboot. Not sure which one of those two actually fixed the issue for people in #203.

[mhartington]

Hmm...

Domain (uk.foon.neovim) not found.
Defaults have not been changed.

After a reboot, same thing.

[ghost]

My two cents: I had exactly the same errors message about msgpack under OSX 10.11.6 (fresh Homebrew install). brew install --HEAD neovim-dot-appbrew install --HEAD neovim-dot-app fixed the problem. Maybe this bug is not OSX Sierra specific ?

[mhartington]

sadly still nothing. Even uninstalling everything, clearing cache, checking defaults and pulling from --HEAD, I still get the same window-less window (if that makes sense)

Is there anymore info I could provide? Not sure what else I can give, but happy to help out some how

[bambu]

Yeah. Neither of the bugs mentioned are Sierra specific. other people have reported them.

• Are the maximize / minimize buttons grey even when Neovim.app has focus? If not then what happens when you maximize it or try to resize the window?
• Is nvim running? You can check with ps awux | egrep -i "(neovim|nvim)" in your terminal when Neovim.app is running.
• Are any messages being reported in Console for Neovim.app?

I'm not sure what else you can try. Any ideas @rogual? The next thing that I personally would do is to put in some print statements in the code or load it in lldb and actually debug it.

[mhartington]

1) Yeah I'm able to maximize/minimize the toolbar, but only it resizes. When I try to toggle full screen, I'll get a full blank screen but nothing there.

2) Yep, neovim is acutally running

3) I cannot see any console messages from neovim.app

[leepa]

I have this same compilation issue on 10.11.6 - so this is not 10.12 specific.

[rogual]

I've released 0.1.5, with the Msgpack 2.0 compatibility fixes, so Homebrew should now use that when you brew install & everything should be OK again.

Hey @leepa, small world :)

[rogual]

Let's keep one issue to an issue, please. This issue is about the compilation failure — please open a new one if you're having other problems.

[mhartington]

Compilation looks good now. Now on to my no-gui issue (aka #203)
