[gs-devel] [PATCH]ghostscript crosscompiling: makefile fixes for host tools

Wed Jan 2 09:59:16 PST 2008

What do you think about this Ray? I still think it would be better to 
duplicate the gp stuff in mkromfs so it can just be built with CCAUX.
That doesn't help with the zlib dependency though, unless we just 
require linked an external version.

This is ugly, but we have to do something like this if we're going to 
support cross-compilation reasonably. And I think we need to do that.

What does the gumstix build do?
