<C-Space> for top level semantic completion doesn't work.

[meh]

Looking at :map it's not even shown, am I doing something wrong?

:messages doesn't show any error either.

Also is there a way to check if semantic completion is actually working?

Printing YouCompleteMe debug information...
-- Flags for /tmp/lol.c:
-- ['-Wall', '-Wextra', '-Werror', '-I', 'include', '-I', 'source', '-I', '/home/meh/projects/vim/config/plugins/you-complete-me/autoload/../python/clang_includes']
-- Has Clang support compiled in: True
-- clang version 3.2 (tags/RELEASE_32/final)

That's the output info, I have math.h included but if I type a it doesn't show acos or anything, is that expected or am I doing something wrong?

Are you trying to call it from console Vim? That probably won't work, depending on your terminal. Most terminals wont't pass Ctrl+Space to Vim. You should remap the key to something else.

Oh, my previous comment applies if you actually got semantic completion working. If you haven't, then try to access a member of a struct or similar.

How do I remap it? How do I check why semantic completion isn't working?

Ok it wasn't working at all because you have to set it to something feasable in the terminal version for it to work, the default should really be changed to something usable in both versions of vim.
