Subject: [SDL] SDL_config_macosx.h: MAC_OS_X_VERSION_MIN_REQUIRED
Hi,
I just compiled my SDL application on Mac OS X with -Wundef and it
threw a number of errors. Of note was:
SDL_config_macosx.h: 34
warning: "MAC_OS_X_VERSION_MIN_REQUIRED" is not defined
Line 34 is:
#if ( (MAC_OS_X_VERSION_MIN_REQUIRED >= 1030) || (!defined (__POWERPC__)) )
Now according to this mailing on the Apple developer lists:
http://lists.apple.com/archives/Xcode-users/2005/May/msg00602.html
that particular #define was removed from the gcc compiler defaults
and AvailabilityMacros.h (/usr/include/AvailabilityMacros.h) should
be pulled in directly instead.
Would someone closer to the Mac OS X version of SDL be willing to
make that change please? Thanks.

since a memory page's size may vary on various architectures and kernel
configurations.
Will use getpagesize() if it exists, the PAGE_SIZE #define from older kernels
if that doesn't, and #error out if that's not there either...but it's
probably 4096 in that case. We may revisit this.
Fixes Bugzilla #392.

Added DirectInput joystick code, contributed by Glenn Maynard.
This fixes a problem with the Windows Multimedia joystick driver
not showing all 6 axes on a GameCube controller converter, which
was donated by Jacob Kolding.
Currently there are two Classic-only drivers defined in "SDL_config_macos.h",
and the ones in "SDL_config_macosx.h" are Mach-O/framework-only (i.e. not CFM)
As a workaround, I disabled CDROM and JOYSTICK when building SDL for CFM
Carbon.
The current SVN trunk is missing the SDLCALL specifier at numerous locations.
It has to be added for all (possibly user provided) callbacks.
I stumbled over this while creating a makefile for the OpenWatcom compiler for
Win32.
- A change to define CXX in fatbuild, which comforts the configure script a little, even if we don't use C++ anywhere.
- Some code to see how many CPU cores exist and parallelize make across them.
- CFLAGS that apply to both archs are specified seperately (-O3, -pipe, etc)
- -fvisibility=hidden for the gcc4 builds
- a "clean", "clean-ppc" and "clean-x86" command
- Fix to SDL_config_macosx.h for the HAVE_ALLOCA_H thing.
Now builds on an Intel Mac.
The SDL platform header shouldn't dictate the OS target API for other
applications. The build system should define the target API for building
SDL internally.
[I'm fixing this for the public headers, but I'm not going to bother for the SDL library code (yet)]
To clarify: Normaly, GCC (or, to be precise, the preprocessor) will ignore
this, and compile the code happily. However, one can specify -Wundef to get a
warning about this.
One can probably argue whether to consider this a bug or not; but I think that
(a) from a semantic point of view, using "#if FOO" when FOO is not defined is
strange, and (b) since it is possible to trigger a warning about this, and a
trivial fix exists, it should be corrected.
I can think of two alternative patches, BTW:
1) Simply use #define HAVE_FOO 0, instead of not defining HAVE_FOO at all
2) Change
#if HAVE_FOO
to
#if HAVE_FOO+0
which always does the right thing.
But I think I still prefer the attached patch :-).
The proper name of Apple's operating system is "Mac OS X" not "MacOS X", as can
bee seen in many places, for example http://www.apple.com/macosx/). This
contrasts the naming of the old operating system, which was called "MacOS" and
today is often refered to as "MacOS Classic".
The attached patches fixes the misuse of the name "MacOS X" in both the SDL12
and sdlweb CVS modules.
The current definition of int32_t, uint32_t, uintptr_t
doesn't match what the Mac system headers already have...
Since it's an old 16/32 bit platform, the system headers
expect the types to use "long" and not "int" like they do.
When switching to "UNIX-style paths" as needed for the new includes,
including <GL/gl.h> and <GL/glu.h> doesn't work anymore on Mac OS...
The two headers are really located in the OpenGL SDK 1.2 CFM like this:
OpenGL:Headers:gl.h
OpenGL:Headers:glu.h
There are also some compat copies, that *used* to work with Mac paths:
OpenGL:Headers:GL/gl.h
OpenGL:Headers:GL/glu.h
The easiest fix is to make SDL_opengl.h include the proper header names,
by adding a special case for the MACOS platform in addition to the MACOSX
SDL_config.h is no longer in CVS. Instead, configure will generate it for
systems that use configure, and we always copy SDL_config.h.default to
SDL_config.h before generating a snapshot or release archive.
Also fixed a couple of uninstall issues.
