- libsdl-PIC-load-mmx-masks-from-stack.patch
this one may be a little controversial ... the fix here is again that you cant
reference the memory addresses like this to load into a mmx register, so the
way to do it is to push two 32bit words onto the stack, load the 64bit value
off of the stack into the mmx register, and then adjust the stack so that
it's back to normal.

Subject: [SDL] More mouse enhancements for Mac OS X

The attached patch brings two more enhancements to mouse handling on Mac
OS X (Quartz):

1. Currently, after launching an SDL application, SDL's notion of the
mouse position is stuck in the top left corner (0,0) until the first
time the mouse is moved. That's because the UpdateMouse() function isn't
implemented in the Quartz driver. This patch adds it.

2. When grabbing input while the mouse cursor is hidden, the function
CGAssociateMouseAndMouseCursorPosition(0) is called, which prevents the
system's notion of the mouse location from moving (and therefore leaving
the SDL window) even when the mouse is moved. However, apparently the
Wacom tablet driver (and maybe other special pointing device drivers)
doesn't care about that setting and still allows the mouse location to
go outside of the window. Interestingly, the system cursor, which is
made visible by the existing code in SDL in that case, does not follow
the mouse location, but appears in the middle of the SDL window. The
mouse location being outside of the window however means that mouse
button events go to background applications (or the dock or whatever is
there), which is very confusing to the user who sees no cursor outside
of the SDL window.

I have not found any way of intercepting these events (and that's
probably by design, as "normal" applications shouldn't prevent the user
from bringing other applications' windows to the front by clicking on
them). An idea would be placing a fully transparent, screen-filling
window in front of everything, but I fear that this might affect
rendering performance (by doing unnecessary compositing, using up
memory, or whatever).

The deluxe solution to the problem would be talking to the tablet
driver using AppleEvents to tell it to constrain its mapped area to the
window (see Wacom's "TabletEventDemo" sample app,
http://www.wacomeng.com/devsupport/mac/downloads.html), but I think that
the bloat that solution would add to SDL would outweigh its usefulness.

What I did instead in my patch is reassociating mouse and cursor when
the mouse leaves the window while an invisible grab is in effect, and
restoring the grab when the window is entered. That way, the grab can
still be effectively broken by a tablet, but at least it's obvious to
the user that it is broken. That change is minimal - it doesn't affect
operation with a mouse (or a trackpad), and the code that it adds is not
executed on every PumpEvents() call, only when entering and leaving the
window.

Unless there are any concerns about the patch, please apply. Feel free
to shorten the lengthy comment in SDL_QuartzEvents.m if you think it's
too verbose.

Thanks

  -Christian

Subject: [SDL] Fix for opening documents on Mac OS X < 10.4

The current code in SDLMain.m that transforms documents opened from the
Finder into command-line arguments (introduced in revision 1.14,
2005-08-11) uses the methods -[NSString lengthOfBytesUsingEncoding:] and
-[NSString getCString:maxLength:encoding:], which are only available in
Mac OS X 10.4.

Compiling this code on 10.3 produces warnings, and running it (i.e.
starting an SDL application by opening a document) leads to weird
behavior which I didn't investigate in detail ("*** -[NSCFString
lengthOfBytesUsingEncoding:]: selector not recognized" is printed to the
console log, and the SDL window never opens).

The attached patch removes the offending calls and uses -[NSString
UTF8String] instead, which is available everywhere. Tested on 10.3.9,
and I see no reason why it shouldn't also work on 10.2 and 10.4.

Two further comments:

* The comment above the -[SDLMain application: openFile:] implementation
says "You need to have a CFBundleDocumentsType section in your
Info.plist to get this message, apparently." This is not the case in my
experience - it worked just fine with a hand-built bare-bones
application consisting only of Test.app/Contents/MacOS/test, without any
Info.plist (although you have to press the option and command keys for
such an application to accept a dragged file).

* I took the liberty of cleaning up another area of SDLMain.m: I changed
"CustomApplicationMain (argc, argv)" to "CustomApplicationMain (int
argc, char **argv)". This avoids the "type of `argv' defaults to `int'"
warnings, and I'm not sure if leaving out the types could cause problems
on platforms where an int and a char** aren't of the same size.

Subject: [SDL] Another mouse bug patch for Mac OS X

Oh my, yet another change in the quartz mouse handling code! :)

The attached patch fixes the following bug:

Calling SDL_WarpMouse() while the cursor is invisible and grabbed should
only update SDL's internal mouse location, not try to warp the system
cursor (which is not at that location, but fixed in the middle of the
window). Otherwise, the next mouse motion event is wrong.

Please apply.

Thanks

Subject: [SDL] [PATCH] Touchscreen support to fbcon via tslib


Hi all!

  I'm new to this list, I just subscribed. I've attached to this e-mail
a patch I've written in order to add Touchscreen support to SDL's fbcon
module via the tslib library.
Since it introduces a new dependency, I've also edited the the
configure.in file and added it as a compile-time option.

This patch is especially useful for handhelds (I've tested it in my
Zaurus).
Please consider applying it. :-)

Hi everybody,

apparently the SDL-1.2.9 source archive could not compile "as is" on
NetBSD 2.0_STABLE due to a pthread detection issue in the configure script.

I attached a small patch that can be applied to configure.in so that SDL
can be directly (i.e. without the NetBSD package manager) configured and
built successfully on NetBSD (at least on the one I tried !).

Hope this helps,

Olivier.

later in November, a similar patch was merged it seems:

however, this lacks the additional output format checks that i posted in my

produce ELF objects, but if this is not true, then the additional checks in
my original patch will need to be merged
