Android haptic code was not added to CMakeLists.txt, leading to build failures when targeting Android platform.
Attached patch adds Android haptic driver to source sets and adds configuration parameter to SDL_config.h.cmake.

That's weird, these are the exact two functions that Emscripten incorrectly believed it had until we upgraded the buildbot's emsdk install.
Not sure what's up with this, but it's possibly not a MingW-specific thing!

Original bug report (note that it was against 2.0.0, it might have been fixed in between): http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=733015

Package: libsdl2-2.0-0
Version: 2.0.0+dfsg1-3
Severity: normal

I have occasional crashes here caused by the X11 backend of SDL2. It seems to
be caused by the X11_Pending function trying to add a high number (> 1024)
file descriptor to a fd_set before doing a select on it to avoid busy waiting
on X11 events. This causes a buffer overflow because the file descriptor is
larger (or equal) than the limit FD_SETSIZE.
Attached is a possible workaround patch.
Please also keep in mind that fd_set are also used in following files which
may have similar problems.
src/audio/bsd/SDL_bsdaudio.c
src/audio/paudio/SDL_paudio.c
src/audio/qsa/SDL_qsa_audio.c
src/audio/sun/SDL_sunaudio.c

I personally experienced this problem while hacking on the python bindings
package for SDL2 [1] (while doing make runtest). But it easier to reproduce in
a smaller, synthetic testcase.

Most ironically, although autoconf/automake-based builds install (pretty half-assed) CMake package configuration files, they're missing in installations resulting from CMake-based builds entirely.
A proper configuration file typically also loads target exports (implemented in patch 3572, also fixing this issue - see my comment on that issue for details).
I believe it would be best to let the dinosaurs go extinct and redirect all build efforts to the CMake end for two reasons:
1. It potentially provides the best user experience, but you'd have to give it some love and ship with less quirky buildfiles.
2. It would force distros to build SDL via CMake and thus would ensure target exports are actually available everywhere.
Various CMake patches I submitted today in summary (directly converted from the HG commits and `am`d onto a fork of a git mirror that happened to be on `tip`).
https://github.com/tschw/SDL/commits/patched
Fixing #2576#3572, #3613, and this fresh ticket, which is almost entirely advertisement ;).
These already do to make SDL much less of a quirky fella to have in your dependency tree...
-Enabling checking for GCC_ATOMICS also on clang by default. This way all Android ABIs build successfully
-Android cmake: Threading was not enabled correctly
-Android cmake: Timers and dynamic lib loading were not included in the sources

The attached patch adds support for KMS/DRM context graphics.
It builds with no problem on X86_64 GNU/Linux systems, provided the needed libraries are present, and on ARM GNU/Linux systems that have KMS/DRM support and a GLES2 implementation.
Tested on Raspberry Pi: KMS/DRM is what the Raspberry Pi will use as default in the near future, once the propietary DispmanX API by Broadcom is overtaken by open graphics stack, it's possible to boot current Raspbian system in KMS mode by adding "dtoverlay=vc4-kms-v3d" to config.txt on Raspbian's boot partition.
X86 systems use KMS right away in every current GNU/Linux system.
Simple build instructions:
$./autogen.sh
$./configure --enable-video-kmsdrm
$make

This patch is wrong: the structure in question has nothing to do with any
gcc version in use. I suggest reverting this adding a conigury check for
it, instead. Something like the following should do it: (configure needs
regenerating.)

When building sdl as shared lib, the version info is lacking in the final binary.
CMake gathers the right resource files into ${VERSION_SOURCES} but then doesn't do anything with them.

SDL2 installs it to /usr/x86_64-pc-linux-gnu/share/aclocal on cross hosts, attached patch makes use of CMAKE_INSTALL_FULL_DATAROOTDIR to support correctly installing to the arch independent location /usr/share/aclocal.

I recently looked into Unicode support in SDL2 and realized that
SDL_TEXTEDITING doesn't get triggered at all (Japanese IME).
According to others on IRC it works fine on Windows/Mac but not
for me on (arch)Linux.
When compiling SDL with autotools, IBus support is enabled by
default but not so with CMake.
I never used CMake before but got it working and also included
that pkg-config determines flags for dbus (FIXME in CMakeLists).
"MACOSX_COREAUDIO" is actually an internal #define set up elsewhere, and
this CMake var is never exported past the CMake script anyhow.
Partially fixes Bugzilla #2807.
With this commit, you can compile SDL2 with Emscripten
( http://emscripten.org/ ), and make your SDL-based C/C++ program
into a web app.
This port was due to the efforts of several people, including: Charlie Birks,
Sathyanarayanan Gunasekaran, Jukka Jylänki, Alon Zakai, Edward Rudd,
Bruce Mitchener, and Martin Gerhardy. (Thanks, everyone!)

SDL's Cocoa backend uses the CGDisplayMode API to get refresh rate information about a display mode, but CGDisplayModeGetRefreshRate will return 0 on most non-CRT monitors.
The only way I know of to get correct refresh rate information in OS X is via the CoreVideo DisplayLink API.
I have attached a patch which tries to use the CVDisplayLinkGetNominalOutputVideoRefreshPeriod function if CGDisplayModeGetRefreshRate fails, which fixes display mode refresh rate information on the monitors I tested.
The CVDisplayLink API requires linking with the CoreVideo framework, and the patch updates the various build files to do so.

Configuring using "cmake -DSDL_STATIC=1 -DSDL_SHARED=0" generate and error in CMakeLists.txt at line 1334:
CMake Error at CMakeLists.txt:1334 (install):

This install rule shouldn't be present when the DLL has been disabled

this patch adds a check to the CMake build script to detect whether the VideoCore API is available.
If it is found, it enables SDL_VIDEO_DRIVER_RPI and will also add the needed include/library directory flags to CMAKE_C_FLAGS so the subsequent check for GLES succeeds in picking up the headers.
Seems to work fine on Raspbian.
I added -Wshadow and then turned it off again because of massive variable shadowing in the blit macros.
Feel free to go through that code and fix these if you want. Just uncomment CheckWarnShadow in configure.in if you want to try this.
The D3D11 renderer is now slightly faster than D3D9 on my Windows 8 machine (testsprite2 runs at 3400 FPS vs 3100 FPS)
This will need tweaking to fix the Windows RT build.

[Exec] CMake Error at cmake_install.cmake:151 (FILE):
[13:37:43][Exec] file INSTALL cannot find
[13:37:43][Exec] "C:/TeamCity/buildAgent/work/2e3d17a492e75daf/Build/libSDL2.so".
The cmake INSTALL project doesn't work because it uses Linux so shared library paths. Windows uses dlls and I think cygwin also uses dlls. I've included this patch. Can you check if it works?
We'll flip the default back to enabled right after 2.0.2 is finalized, and
try to declare them stable and ready by 2.0.3.
Those that have an interest in supporting them in 2.0.2 can manually enable
them in the configure script with --enable-video-wayland and/or
--enable-video-mir.
