gocode: The only autocompletion I get is PANIC

Hello,

Just installed gocode a few minutes earlier and all attempts to get it to work in vim failed. Ultimately, I started a server manually (gocode -s) and then using the gocode client in command line, I tried: “gocode autocomplete math.F” and that resulted in a:

Found 1 candidates:
  PANIC PANIC PANIC

Verifying the server window that showed:

I am using Go version: go version devel +f4d1cb8d9a91 Thu Sep 19 22:34:33 2013 +1000 linux/amd64

Please let me know if there’s any other info I can provide.

Thank you, really looking forward to using this in Vim 😃

Here’s the one liner to update gocode

gocode close && go get -u github.com/nsf/gocode

Oh, I forgot to tell you to actually restart gocode. Because if you updated it, it won’t work as is, since there is an actual process running already. Do: gocode close. It will kill the server and will start a new one automatically. Or just reboot if you wish.

Turned out I was fighting in vain for very long … I had to delete the /tmp/gocode-daemon.samuel socket first, which was revealed when trying to start a new gocode server with gocode -s. So, just for reference:

[samuel test]$ gocode -s
2014/09/08 14:18:06 unix socket: '/tmp/gocode-daemon.samuel' already exists
[samuel test]$ rm /tmp/gocode-daemon.samuel
[samuel test]$ gocode -s

(Then of course, adopt to whatever the name is in “unix socket [file name] already exists”)

atom got this problem ; gocode close && go get -u github.com/nsf/gocode ; reopen atom; works like a charm

Yeah, I kind of regret not embedding the version info into gocode binaries and checking those on each client/server communication. Could solve some of your user experience issues.

If the gocode version and go compiler version mismatch, it’s possible. You need to make them up to date. I don’t recommend installing gocode and go from distribution repositories, because it’s easy to do manually.

sudo apt-get remove gocode

@samuell , in vim-go , go1.7 , have the same problem

gocode close didn’t work for me. Had to remove gocode listed at which -a gocode and reinstall it via go get -u.
