MacOSX 10.8 ("Mountain Lion") defaults to trying to use automated reference counting on certain objects. This means that the system header files will use some Objective C syntax constructs even when compiling pure C, which confuses mainline gcc. Suppress this by setting OS_OBJECT_USE_OBJC=0. This avoids a compile error like this: In file included from /System/Library/Frameworks/Foundation.framework/Headers/NSObject.h:5:0, from /usr/include/os/object.h:74, from /usr/include/dispatch/dispatch.h:48, from /System/Library/Frameworks/IOKit.framework/Headers/IOKitLib.h:56, from block/raw-posix.c:35: /System/Library/Frameworks/Foundation.framework/Headers/NSObjCRuntime.h:409:1: error: stray ‘@’ in program [with a large number of further run-on errors] Signed-off-by: Peter Maydell <peter.maydell@linaro.org> --- configure | 3 +++ 1 file changed, 3 insertions(+)
