Class MMBackend is implemented in both... #628

Closed ahmedelz closed 6 years ago

ahmedelz commented 6 years ago

I'm running MacVim version 8.0.1420 on macOS High Sierra (10.13.3). When calling gvim from (/Applications/MacVim.app/Contents/bin/gvim), I see the following messages displayed in the Terminal.

objc[15853]: Class MMBackend is implemented in both /Applications/MacVim.app/Contents/bin/../MacOS/Vim (0x105aec8e0) and /Applications/MacVim.app/Contents/MacOS/Vim (0x20879e8e0). One of the two will be used. Which one is undefined.

Any suggestions on what to do to suppress these messages or does this need a new build?

splhack commented 6 years ago

I can't repro it. please try binary release https://github.com/macvim-dev/macvim/releases or https://github.com/macvim-dev/homebrew-macvim

ahmedelz commented 6 years ago

I still can reproduce issue. I was indeed using snapshot build 144 from https://github.com/macvim-dev/macvim/releases. I updated to snapshot build 145 (MacVim version 8.0.1522) and still see the messages.

ahmedelz commented 6 years ago

The message comes out when gvim binary is used to launch MacVim: /Applications/MacVim.app/Contents/bin/gvim

splhack commented 6 years ago

Could you show me what the output looks like of

$ ls -lai /Applications/MacVim.app/Contents
$ ls -lai /Applications/MacVim.app/Contents/bin
$ ls -lai /Applications/MacVim.app/Contents/MacOS

It seems that the links in /Applications/MacVim.app/Contents/bin were created using a different group. I removed the links and recreated them with the same username:group.

I have no idea what's going on. probably I can't do anything for the issue.

@DevByStarlight while troubleshooting another issue I came across this report and noticed you are using an old dead version of kien/ctrlp.vim the new one is at ctrlpvim/ctrlp.vim you might want to switch.
