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.

devices, since they are probably joysticks, or joystick-like things.
See 3Dconnexion's SpaceNavigator for an example of such a device:

we don't need it, and doing so will hit #error lines on some CPU archs.
Thanks to Mike Frysinger for the heads up.

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.

ScrollLock, and Pause, since that's what's on the standard Apple keyboards
(minus the laptops, which have neither set). Ideally we'll find a better way
to distinguish this...the keys being replaced would be correct on a USB
keyboard for Windows. Sigh.
Fixes Bugzilla #301.

(But what if this finds the wrong symbol? We really should make this a
./configure test and only do one dlsym or the other depending on the
platform...)

Subject: [SDL] Alpha blending bug - fixed?
It turns out mm5 never got the correct value. This failed :
[...]
"movd %1, %%mm5\n\t"
: : "m" (amask), "m" (sf->Ashift) );
mm5 got 0xFF000018 instead of 0x00000018. However I did this :
Uint32 ashift = sf->Ashift;
[...]
"movd %1, %%mm5\n\t"
: : "m" (amask), "m" (ashift) );
and everything worked fine.
The only thing I could find out was that ashift is 32-bit aligned but
sf->Ashift isn't:
printf("ashift %8X [%d]\n", &ashift, (int)(&ashift) % 4);
printf("sf->Ashift %8X [%d]\n", &sf->Ashift, (int)(&sf->Ashift) % 4);
ashift at BFF0E0C4 [0]
sf->Ashift at 08AFB9CD [1]
Could this be the problem? If it is, the fix is extremely trivial.
Should I submit a patch?

outside of the window when the grab was initiated.
Fixes Bugzilla #299, which has a more detailed explanation of the issue.

I might be on crack here.
It looks like SDL_ConvertMono() in src/audio/SDL_audiocvt.c adds the left and
right channels of a stereo stream together, and clamps the new mono channel if
it would overflow.
Shouldn't it be dividing by 2 to average the two sample points instead of
clamping? Otherwise the mono sample point's volume doubles in the conversion.
This would also make the conversion faster, as it replaces two branches per
sample frame with a bitwise shift.
