[Qemu-devel] [PATCH 1.0] configure: add '--disable-cocoa' switch

[Qemu-devel] [PATCH 1.0] configure: add '--disable-cocoa' switch

[Pavel Borzenkov]

When SDL support is disabled, there is no way to build QEMU without
Cocoa support on MacOS X. This patch adds '--disable-cocoa' switch and
allows to build QEMU without both SDL and Cocoa frontends.

This is a new feature and therefore too late for 1.0. Only bugfixes now.

I remember there was a similar patch once but some issue with it kept us
from applying it - something unrelated to the frontend was influenced by
it I think... block layer?

Without looking at the context, this hunk looks weird. You sure you're
not breaking the SDL default for other platforms?

Anyway, I would much more appreciate a bugfix or suggestion how to make
Cocoa build than to disable it altogether (and then only based on a
configure option).

Yeah, block/raw-posix.c has a pile of #ifdef CONFIG_COCOA in it,
which it looks like it's using to mean "am I on MacOSX?"

Yes, I see it now. I'll modify the file to use some pre-defined Mac OS X macro,
so CONFIG_COCOA will control only Cocoa frontend build.

Yeah, I did break it, at least for Linux. I'll fix this in the next version.

This breaks SDL probing on Linux.

This is what normally enables SDL.
