I have generated tags using ctags -R .

In Vim I'm able to find the tag when I type :tag TagName and it does jump to it.

However, if I have a cursor over the TagName and do Ctrl+] vim shows cstag: tag not found.

I know indeed the TagName is in the tags file but why I'm not able to jump with the short-cut key? There are some tags I'm able to jump with Ctrl+] not sure why. Also I have set tags=~/Mycode/tags.

  • It sounds like you have cscope enabled. Try set nocscopetag

  • Thanks Mass! yes this does fix the issue :) does this mean i can't have ctags with cscope enabled at the same time?

  • @JZ67 well, if you have cscopetag, it overrides the :tag commands. You can have both, but you'd have to use the individual commands (:help :cscope and :help :tag)

With cscopetag enabled, you get E257 on tags not being found (credits Mass in the comments).

Fortunately, the help for this error contains useful information: use :cstag! It can do searches in both; precedence is controlled by 'cscopetagorder'.

Of course, the error and description of cscopetag make it sound like the tag wasn't found after searching both, so that's a different issue.

  • Mass's suggestion "set nocscopetag" worked for me. Interestingly now after i set my tags dir in vimrc according to:vi.stackexchange.com/questions/29030/… Now jump to the tag works perfectly, i can even comment out "nocscopetag"
