If you cd to some directory and execute "ctags -R", the resulting
tags file will contain path names relative to that directory, making
it difficult to use the tags when Vim is started in any other
directory. A solution to this is to give ctags the absolute path
names of the directories you wish to search. In your case, you
could execute ctags as
ctags -R /src
or as
ctags -R /src/thread /src/device
Additionally, you can specify the location for the tags file with
the -f option, e.g.,
ctags -f /src/thread/tags -R /src
and you can tell Vim where that tags file is with
:set tags=/src/thread/tags
Then it won't matter where you start Vim, it will be able to find
the tags file and the tags commands (e.g., C-]) will be able to find
the target files.
HTH,
