Semantic seems to be able to do this, but I cannot get it to work as I would expect it to. For example, if I #include "Type.h" and declare Type t, using semantic-complete-analyze-inline when point is after t. consistently gives me the error
Cannot find types for `Type t'
instead of giving me all of the public (or otherwise appropriate) members of t.
How can I get the result I'm looking for here? Ideally, how can I use whatever Semantic might provide as a backend for Company?
I suggest using irony-mode with company-irony for completion instead of semantic as semantic is generally too slow and simplistic - ie. it often doesn't offer completions when you would think it should.
You probably want to follow the tutorial here and setup company-clang to get better candidates.
First you need to initialize CEDET and ede

;; You can add this to improve the parse of macro-heavy code:

(add-to-list 'semantic-lex-c-preprocessor-symbol-file "/usr/lib/gcc/x86_64-redhat-linux/4.4.7/include/stddef.h")

If not, you'll want to add prepend it to the first of the list so that it's searched first – cheezy Nov 10 '14 at 20:26company-semanticis incompany-backends; thanks :) – Sean Allred Nov 10 '14 at 21:02
