The new source files for coremotion sensors don't seem to have been included correctly in configure.in. This leads to the build script ios-build.sh to fail at link time, complaining about missing symbols, namely about missing SDL_COREMOTION_SensorDriver.
Fixes a race where we try to build version res file in build directory
before it has even been created. Prevents errors like:
/bin/bash ../SDL2-2.0.10/build-scripts/updaterev.sh
/bin/bash ../SDL2-2.0.10/build-scripts/mkinstalldirs build
mkdir -p -- build

While the CMake build checks for ibus and does enable the ibus backend with set(HAVE_IBUS_IBUS_H TRUE), this does not define SDL_USE_IME, thus CMake built SDL2 (as in Arch Linux) cannot use IME at all.
The attached patch fixes this behaviour when building against ibus. IME support will still fail when only fcitx is available on the build system.
This is currently supported on Linux and macOS. iOS and Android are not
supported at all, Windows support could be added with some changes to the libusb
backend. The Visual Studio and Xcode projects do not use this feature.
Based on Valve Software's hid.cpp, written in collaboration with Andrew Eikum.
(and it defaults to "yes" on those platforms. Other places, which use libusb,
still default to no because they probably need root permissions to work.)

A horde of strict aliasing violation warnings are emitted from joystick
layer, and also from a few other places. This happens with gcc-4.4.7 on
Linux CentOS 6.10. Some other sysjoystick would possibly have the same
warnings.
Attached my full log here. Example entry:
src/joystick/SDL_joystick.c: In function 'SDL_GetJoystickGUIDInfo':
src/joystick/SDL_joystick.c:1094: warning: dereferencing pointer '({anonymous})' does break strict-aliasing rules

The evdev interface is available on FreeBSD, with the xf86-input-evdev for include files in /usr/local/include/linux, so <linux/input.h> works, or when build with the native evdev option, where <dev/evdev/input.h> is available.
This lets you build a custom embedded device that roughly offers the "this
process is going to the background NOW" semantics of SDL on a mobile device.

I am having a parallel build problem with -j3 or higher using the autotools build and slibtool instead of GNU libtool. Basically slibtool is faster than GNU libtool and it will start working before mkdir starts or finishes creating the build/ directory.
From Tom Black:
I'm having problems initializing the sensor module. I'm compiling with a standard ./configure && make && sudo make install, and the module says it's enabled, but SDL_Init(SDL_INIT_EVERYTHING) is failing with SDL_GetError() returning "SDL not built with sensor support".
add HAVE_ENDPOINTVOLUME_H, HAVE_MMDEVICEAPI_H and HAVE_AUDIOCLIENT_H
in SDL_config.h.in, SDL_config.h.cmake, SDL_config_windows.h, and in
SDL_config_winrt.h.
Now you don't need the latest Wayland installed to build with
newer protocols supported, as they'll build correctly; even if
your system can't use them, we can make intelligent decisions
at runtime about what's available on the current machine anyhow.
This also simplifies some logic and possible failure cases in
the configure and CMake scripts.
Fixes Bugzilla #4207.
This is just in parity with the existing zxdg-shell-unstable-v6 code. Making
the Wayland target robust (and uh, with title bars) is going to take a lot
of work on top of this.

Running top-level SDL configure on macOS 10.11 resulted in the errors below because automake removed the brackets about the tests.
./configure: line 15756: : command not found
./configure: line 15759: -Iinclude -I/Users/zack/SDL/include -idirafter /Users/zack/SDL/src/video/khronos : No such file or directory

When you try use SDL2 2.0.8 in CMake project in Linux, it complains about trailing spaces in sdl2.pc:
CMake Error at CMakeLists.txt:147 (add_executable):
Target "TestSimpleMain" links to item "-L/usr/lib64 -lSDL2 " which has
leading or trailing whitespace. This is now an error according to policy
CMP0004.

Configury adds Metal.framework to linkage even if it is not available.
My solution is setting enable_render_metal to no when Metal.framework
is not found
This is meant to be the desktop-enhanced version of wl_shell. Right now we
just match what the existing wl_shell code does, but there are other areas of
functionality available to us now, that we can fill in later.
This uses the "unstable" API, since this is what ships in Ubuntu 17.10 (as
part of Wayland 1.10), but Wayland 1.12 promotes this to stable with extremely
minor changes. We will add support for the stable version when it makes sense
to do so.
New functions get and set the YUV colorspace conversion mode:
SDL_SetYUVConversionMode()
SDL_GetYUVConversionMode()
SDL_GetYUVConversionModeForResolution()
SDL_ConvertPixels() converts between all supported RGB and YUV formats, with SSE acceleration for converting from planar YUV formats (YV12, NV12, etc) to common RGB/RGBA formats.
Added a new test program, testyuv, to verify correctness and speed of YUV conversion functionality.

When RWops seeks with fseek or fseeko it uses the types long or off_t which can be 32 bits on some platforms. stdio_seek does not check if the 64-bit integer for the offset fits into a 32-bit integer. Offsets equal or larger than 2 GiB will have implementation-defined behavior and failure states would be very confusing to debug.
The attached patch adds range checking by using the macros from limits.h for long type and some bit shifting for off_t because POSIX couldn't be bothered to specify min and max macros.
It also defines HAVE_FSEEKI64 in SDL_config_windows.h so that the Windows function gets picked up automatically with the default config.
And there's an additional error message for when ftell fails.

When compiling SDL for the Raspberry Pi, I have to use the --host parameter to enable compilation of the native Raspberry Pi video driver, like so:
--host=arm-raspberry-linux-gnueabihf
It took me a while to figure out that this was necessary in order to have the native Raspberry Pi video driver compiled in. I think it would be better if there was an option like --enable-video-rpi that could be passed to configure and that would also show up when saying configure --help. Currently, it?s rather difficult to figure out that you have to use the --host parameter with arm-raspberry-linux-gnueabihf in order to get Raspberry Pi video support. It?s also somewhat inconsistent because most other video drivers can in fact be enabled/disabled through specific configure parameters but there is no such parameter for the native Raspberry Pi video driver.

Cmake checks for float.h, but configure does not: the attached patch
adds float.h to checked headers in configury, and it adds the missing
HAVE_FLOAT_H macro to SDL_config.h.cmake and SDL_config.h.in.
In SDL_config_macosx.h and SDL_config_windows.h, defined HAVE_FLOAT_H
as 1, where I know that it's true.

Using the pre-built x86 devel libs from here:

If I have:
SDL_GL_SetAttribute(SDL_GL_CONTEXT_PROFILE_MASK, SDL_GL_CONTEXT_PROFILE_ES);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 2);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, 0);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_FLAGS, SDL_GL_CONTEXT_DEBUG_FLAG);
and I'm using ANGLE/(a GL driver that doesn't provide an ES2 context) such that SDL_EGL_CreateContext is called by SDL_GL_CreateContext, I get the error "Could not create EGL context (context attributes are not supported)" and no context is created.
Looking at the code in SDL_EGL_CreateContext - if gl_config.flags is non-zero, it looks like the code in the section guarded with "#ifdef EGL_KHR_create_context" should be executed - but it apparently isn't.
Is it possible this section hasn't been compiled into the pre-built libraries? If I build SDL2.dll myself using the Visual C++ solution (VS2015 Community Update 3) then the call succeeds as I expect

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!
