[Barrelfish-users] CC variable

[Timothy Roscoe]

Hi Georgios,

We made an early decision to bury the binding of the C compiler fairly 
deep down in Hake's architecture abstractions.  If there really is a 
pressing need to specify the C compiler differently for different 
modules in the same build architecture, we would need to add the 
compiler name to the (ever-expanding) Opts record.  This is doable, but 
it's a bit of work.

One alternative is to explicitly compile the C files by writing 
low-level Hake combinators in your Hakefile.  Hake won't compile (or 
calculate dependencies for) any C files which you don't explicitly hand 
it, so you can treat any C file specially if you're prepared to forego 
the convenience of the "build library" or "build application" functions. 
  This might be the easiest way forward for a small module (how big is 
it?).

This does require a bit more understanding of how Hake works, but most 
of what you need should be in the Technical Note.

Hope this helps a bit...
