Subject: Re: About QNX support in SDL 1.3
Here is another batch of patches.
1) Makefile.in - added SDL_opengles.h header as header to install.
2) configure.in - Added special define to detect Common Lite OpenGL ES
library in case if Common library is not installed. Added check for
clock_gettime in libc (in QNX it is in libc).
3) SDL_config.h.in - Added SDL_VIDEO_RENDER_OPENGL_ES and
SDL_VIDEO_OPENGL_ES declarations for configure script autodetection.
4) SDL_opengles.h - Added GL_API definition if it is not defined. Added
extension GL_OES_draw_texture because OpenGL ES Renderer uses it without
declaration. Added GL_OES_vertex_buffer_object extension, which is supported
under QNX OpenGL ES. Added GL_OES_single_precision extension.
5) To the test directory I've added building OpenGL ES test applications
through the autotools suite. Was support for iPhone IDE building only.

Subject: About QNX support in SDL 1.3
Right now I'm working on QNX SDL 1.3 drivers implementation and looks like a
lot of code must be completely reworked. But I'm ready for it :) Also I want
to add QNX Graphics Framework SDL driver, which is fullscreen graphics
framework, with support of hardware accelerated OpenGL ES implementations.
This Graphics Framework (called GF in QNX) could also use QNX Photon (window
manager GUI) as window manager.
In the attachment initial patch for QNX support in SDL 1.3
* Some math functions become intrinsic in release mode, so we need to
convert all the math functions into SDL math functions, like we did
with the stdlib functions.
* Constant initializers of 8-bit values become calls to memset() in
release mode, but memset() itself is an intrinsic when explicitly
called. So we'll just explicitly call memset() in those cases.
Subject: SDL. macos build problem
When I try to cross-build SDL1.3 r4362 it fails for macos. It seems there
is a typo in configure.in. Please, consider attached patch.

Subject: SDL1.3 DirectFB patches
The attached contains the following directfb changes:
- Dynamic loading of libdirectfb.so. This may to turned off as well in configure
- Use linux-input by default. May be switched off by environment variable.
- Added some code which will use directfb's x11 backend when DISPLAY is set.

Subject: Fusionsound audio driver
attached is a diff containing a audio driver for the FusionSound
library. This sound library is closely related to DirectFB and uses the
same transport (fusion) as DirectFB when running applications "remote",
i.e. over the network. As such, it natively redirects sound where
DirectFB redirects video. This may be handy for everyone using SDL over
DirectFB.
One or two things got moved around, but largely this is hooked up correctly
in the Unix configure system now: it can be dynamically loaded and fallback
gracefully if not available, or libXi can be directly linked to libSDL.
XInput support can be --disable'd from the configure script, too (defaults to
enabled).
Please note that while the framework is in place to gracefully fallback, the
current state of the source requires XInput. We'll need to adjust a few
things still to correct this.
Many-mouse and tablet support

Everything concerning the project is noted on the wiki:
http://wilku.ravenlord.ws/doku.php?id=start
Prepping for using MMX and SSE intrinsics instead of inline assembly.
.. except for memcpy equivalents which only get faster if they can
exploit the parallelism of loading into multiple SIMD registers. :)
available and to keep people form having to install yet another library I have added the essential parts of Xmu in
src/video/extensions/XmuStdCmap and an include file in src/video/extensions. The support makes use of standard X11 mechanisms to
create color maps and make sure that an application uses the same color map for each window/visual combination. This should make it
possible for gamma support to be implemented based on a single color map per application.
Hurm... it looks like "make indent" modified a few extra files. Those are getting committed too.

Hello !
As alloca.h is not available on CYGWIN and MinGW32
it should not be checked there or it should be checked
with -mno-cygwin using.
I am a total configure.in newbie, but i found the way
that things are handled in configure.in pretty bad for the
case CYGWIN with MinGW Mode or not.
Maybe this is not possible but i would like to
have a way to detect at the start for example CYGWIN
and then add. ask if configure was called with --enable-cygwin
for example. --enable-cygwin should be optional and disabled
by default as we want to have MinGW Mode by default.
Only if the user wants it he should be able to use it.
Then the whole configure.in would get add. questions
okay the system is CYGWIN with or without MinGW Mode.
The alloca.h thing for example is only
available under CYGWIN ( without MinGW Mode ).

Hi,
if "configure" is given an explicit --libdir, the sdl-config still contains
the default "${exec_prefix}/lib" for runtime linker path.
That should be changed to $libdir, as this is where the library goes to...

[patch tweaked to handle older nasm, which doesn't support :function syntax]

libsdl-hidden-nasm.patch
here's the patch i posted here:
http://www.libsdl.org/pipermail/sdl/2006-March/073618.html
this will hide the symbols dynamically if the build nasm/yasm supports the
hidden stuff ... in other words, this patch should be safe with both older and
new versions of nasm/yasm
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.

Subject: [SDL] [patch] touchup configure --help output
the current output includes a lot of "default=yes" stuff in it ... except that
it lacks the [] around it
patch attached to fix the situation
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.
The attached patch is mostly cosmetic: Currently, we always add both -framework
OpenGL and -framework AGL for Mac OS X command line builds.
However, the former is only used for the Cocoa video driver, and the latter
only for the Carbon video driver (as far as I can tell, at least). Hence the
attached patch modifies configure.in so that each only gets added to the list
of frameworks if the corresponding video driver is enabled.
The change made to sdl-config.in on March 18 (rev 11, see
http://www.libsdl.org/cgi/cvsweb.cgi/SDL12/sdl-config.in), broke static linking
under Mac OS X for unix style build systems. In other words, "sdl-config
--static-libs" no longer produces the correct output, as it is missing the
required -framework switches.
The attached patch fixes this.
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 attached patch changes configure.in to use "-framework FOO" instead of
"-Wl,-framework,FOO".
This avoid some issues with certain versions of libtool that do not handle
-framework properly.
Some versions of libtool will try to reorder the two parts of the option, or
render the 2nd part of the argument to the relative path of a non-existent
library.
Note: It is not enough if SDL uses a version of libtool that does this
correctly, because these -framework options show up in "sdl-config --libs".
Hence, some 3rd party apps which still ship with an old libtool have troubles
compiling under Mac OS X.
The configure script parses the value of $X_LIBS when looking at the
--enable-x11-shared, which is getting set on Ubuntu 5.10 to "-L/usr/X11R6/lib"
... however, Ubuntu stores all the Xlib stuff in /usr/lib.
The end result in SDL is that the dynamic X11 stuff gets disabled by default,
unless you override like this:
./configure --x-libraries=/usr/lib

Subject: [SDL] no software surfaces with svgalib driver?
Hi,
I noticed that the SDL (1.2.9) svgalib driver only makes use of linear
addressable (framebuffer) video modes. On older systems (like one of
mine), linear addressable modes are often not available.
Especially for cards with VESA VBE < 2.0 the svgalib vesa driver is
unusable, since VESA only supports framebuffering for VBE 2.0 and later.
The changes necessary to add support for software surfaces seem to be
relatively small. I only had to hack src/video/svga/SDL_svgavideo.c (see
attached patch). The code worked fine for me, but it is no more than a
proof of concept and should be reviewed (probably has a memory leak when
switching modes). It also uses the vgagl library (included in the
svgalib package) and needs to be linked against it.

From the autoconf obsolete macros documentation:
Macro: AC_CANONICAL_SYSTEM
Determine the system type and set output variables to the names of the canonical system types. See section Getting the Canonical System Type, for details about the variables this macro sets.
The user is encouraged to use either AC_CANONICAL_BUILD, or AC_CANONICAL_HOST, or AC_CANONICAL_TARGET, depending on the needs. Using AC_CANONICAL_TARGET is enough to run the two other macros.
From the documentation for the canonical environments:
case $target in
i386-*-mach* | i386-*-gnu*)
obj_format=aout emulation=mach bfd_gas=yes ;;
i960-*-bout) obj_format=bout ;;
esac
Note that the above example uses $target because it's taken from a tool which can be built on some architecture ($build), run on another ($host), but yet handle data for a third architecture ($target). Such tools are usually part of a compiler suite, they generate code for a specific $target.
However $target should be meaningless for most packages. If you want to base a decision on the system where your program will be run, make sure you use the $host variable.

Subject: Re: Updating SDL for RISC OS
I've attached a zip file with three diffs to get SDL to build on RISC OS.
configure.in.diff and makedeps.sh.diff have been modified so that they
can build the assembler file in video/riscos. You may want to double
check these as I don't know a lot about unix shell programming.
(I've tested them cross-compiling on cygwin).
sdlsysthread.diff is the changes required to SDL_systhread.c for RISC
OS. As you suspected with these changes in place you can delete the
RISC OS specific threading code in thread/riscos.
I've also renamed SDL_riscosASM.s to SDL_riscosASM.S, but I'm never
quite sure how to rename files in CVS, so if you could to this it would
be appreciated.

Subject: Re: [SDL] CVS stable again, please update SDL ports
Some problems are caused on Tru64 UNIX.
If applying SDL12-osf1.path, these problems are fixed.
1. configure-script say "recursive mutexes... no" and "pthread
semaphores... no".
checking for pthreads... yes
checking for recursive mutexes... no
checking for pthread semaphores... no
This is because it compiled without pthread_cflags and pthread_lib when
checking recursive mutexes and pthread semaphores.
2. Compiling src/audio/mme/SDL_mmeaudio.c fails.
