Re: [Xen-devel] Build process
Even if we fixed our Makefiles (and I'm not sure we can -- if we use
'?=' then we don't get 'gcc' by default because it appears CC is set
to 'cc' already) your beef is with the Linux build system. In the
Linux build system there is no way to change the compiler name to
anything other than $(CROSS_COMPILE)gcc [you can set CROSS_COMPILE
though].
Have you tried tricks like creating a symlink in a local directory to
your preferred compiler and adding it to your PATH? e.g.,
# ln -sf `which ccache' gcc
# PATH=`pwd`:$PATH make
