I've been trying to get VIM to compile c++ code using clang++ based on the above
comments as I prefer its debug output over gcc. Unfortunately so far without
much success and Google does not really help me in finding a solution. So I hope
that someone can point me in the correct direction as I would like to see how
the vim autocompletion works. 

I'm currently using the 2.9 branch of clang + llvm on FreeBSD stable and can
compile a hello world program from the commandline directly so both clang and
clang++ are in the path. However when running vim with the above vimrc file I
however fail to compile the same bit of code from within VIM (using :make
<program name>). 

In this I set make in VIM to cLang by typing :set makeprg=clang in VIM. Yet the
output I get makes no sense to me although it clearly is using clang to do the
compile. Hopefully somebody can point out what I do wrong here? 

fyi) below is the compiler or linker output I get when running :make hello
although it probably is not relevant. The same code compiles without problems
when compiling from the CMD-line
