Apparently the "-x objective-c" made it down to the linker, who then treats

the same thing but gets ignored by the linker.

Sam Lantinga a8400dc3bf Fixed bug 5105 - sndio support not working in dynamic mode (dlopen)
Giovanni Bajo

The CMake build system supports several audio frameworks for Linux: one of them is sndio.

All frameworks can be built with "runtime linking" (that is, using dlopen to load the library at runtime). In sdlchecks.cmake, there's code to do the same with sndio:

=================================================================
# Requires:
# - n/a
# Optional:
# - SNDIO_SHARED opt
# - HAVE_DLOPEN opt
macro(CheckSNDIO)
  if(SNDIO)
    # TODO: set include paths properly, so the sndio headers are found
    check_include_file(sndio.h HAVE_SNDIO_H)
    find_library(D_SNDIO_LIB sndio)
    if(HAVE_SNDIO_H AND D_SNDIO_LIB)
      set(HAVE_SNDIO TRUE)
      file(GLOB SNDIO_SOURCES ${SDL2_SOURCE_DIR}/src/audio/sndio/*.c)
      set(SOURCE_FILES ${SOURCE_FILES} ${SNDIO_SOURCES})
      set(SDL_AUDIO_DRIVER_SNDIO 1)
      if(SNDIO_SHARED)
        if(NOT HAVE_DLOPEN)
          message_warn("You must have SDL_LoadObject() support for dynamic sndio loading")
        else()
          FindLibraryAndSONAME("sndio")
          set(SDL_AUDIO_DRIVER_SNDIO_DYNAMIC "\"${SNDIO_LIB_SONAME}\"")
          set(HAVE_SNDIO_SHARED TRUE)
        endif()
      else()
        list(APPEND EXTRA_LIBS ${D_SNDIO_LIB})
      endif()
      set(HAVE_SDL_AUDIO TRUE)
    endif()
  endif()
endmacro()
=================================================================

The feature is gated by an option called SNDIO_SHARED. It is also fully implemented in SDL_sndioaudio.c

Unfortunately, it seems there is a missing line in CMakeLists.txt, so SNDIO_SHARED is not defined:

======================================================================
set_option(ALSA                "Support the ALSA audio API" ${UNIX_SYS})
dep_option(ALSA_SHARED         "Dynamically load ALSA audio support" ON "ALSA" OFF)
set_option(JACK                "Support the JACK audio API" ${UNIX_SYS})
dep_option(JACK_SHARED         "Dynamically load JACK audio support" ON "JACK" OFF)
set_option(ESD                 "Support the Enlightened Sound Daemon" ${UNIX_SYS})
dep_option(ESD_SHARED          "Dynamically load ESD audio support" ON "ESD" OFF)
set_option(PULSEAUDIO          "Use PulseAudio" ${UNIX_SYS})
dep_option(PULSEAUDIO_SHARED   "Dynamically load PulseAudio support" ON "PULSEAUDIO" OFF)
set_option(ARTS                "Support the Analog Real Time Synthesizer" ${UNIX_SYS})
dep_option(ARTS_SHARED         "Dynamically load aRts audio support" ON "ARTS" OFF)
set_option(NAS                 "Support the NAS audio API" ${UNIX_SYS})
set_option(NAS_SHARED          "Dynamically load NAS audio API" ${UNIX_SYS})
set_option(SNDIO               "Support the sndio audio API" ${UNIX_SYS})
set_option(FUSIONSOUND         "Use FusionSound audio driver" OFF)
dep_option(FUSIONSOUND_SHARED  "Dynamically load fusionsound audio support" ON "FUSIONSOUND" OFF)
======================================================================

You can see that all frameworks define a "dep_option" NAME_SHARED, and SNDIO is the only one where the option is missing.

This means that runtime loading of sndio is never activated. If sndio is found at configuration time, it is always activated in "linked" mode, so that the final binary will have a load-time dependency with libsdnio. This is unfortunate.

To fix the problem, it is sufficient to add this line:

dep_option(SNDIO_SHARED        "Dynamically load the sndio audio API" ${UNIX_SYS} ON "SNDIO" OFF)

I've verified that this fixes the bug, and sndio can now be dynamically loaded as expected.

Sam Lantinga eadc8693dd Fixed bug 5103 - Port fcitx support to both fcitx 4 & 5
wengxt

Due to the new major fcitx version is coming close, the existing code need to be ported to use new Fcitx dbus interface.

The new dbus interface is supported by both fcitx 4 and 5, and has a good side effect, which is that it will work with flatpak for free. Also the patch remove the dependency on fcitx header. Instead, it just hardcodes a few enum value in the code so need to handle the different header for fcitx4 or 5.

James Le Cuirot abcc6706fd build: Don't duplicate Libs in Libs.private in pkg-config file
pkg-config already prepends Libs to Libs.private when you specify
--static so there's no need to duplicate them. Most other projects
don't do this.
2020-04-12 13:24:36 +01:00
James Le Cuirot 99f87a7158 build: Merge pkg-config Libs.private into Libs for static-only builds
A project being built entirely statically will call pkg-config with
--static, which utilises the Libs.private field. Conversely it will
not use --static when not being built entirely statically, even if
there is only a static build of SDL available. This will most likely
cause the build to fail due to underlinking unless we merge the Libs
fields.

This is what the Meson build system does when it generates pkg-config
files. This also also follows the behaviour of sdl2-config.

At the same time, the runtime linker flags are not applicable to
static-only builds so only add them for shared builds.

Sam Lantinga 2be75c6a61 Fixed bug 5028 - Virtual Joysticks (new joystick backend)
David Ludwig

I have created a new driver for SDL's Joystick and Game-Controller subsystem: a Virtual driver.  This driver allows one to create a software-based joystick, which to SDL applications will look and react like a real joystick, but whose state can be set programmatically.  A primary use case for this is to help enable developers to add touch-screen joysticks to their apps.

The driver comes with a set of new, public APIs, with functions to attach and detach joysticks, set virtual-joystick state, and to determine if a joystick is a virtual-one.

Use of virtual joysticks goes as such:

1. Attach one or more virtual joysticks by calling SDL_JoystickAttachVirtual.  If successful, this returns the virtual-device's joystick-index.
2. Open the virtual joysticks (using indicies returned by SDL_JoystickAttachVirtual).
3. Call any of the SDL_JoystickSetVirtual* functions when joystick-state changes.  Please note that virtual-joystick state will only get applied on the next call to SDL_JoystickUpdate, or when pumping or polling for SDL events (via SDL_PumpEvents or SDL_PollEvent).


Here is a listing of the new, public APIs, at present and subject to change:

------------------------------------------------------------

/**
 * Attaches a new virtual joystick.
 * Returns the joystick's device index, or -1 if an error occurred.
 */
extern DECLSPEC int SDLCALL SDL_JoystickAttachVirtual(SDL_JoystickType type, int naxes, int nballs, int nbuttons, int nhats);

/**
 * Detaches a virtual joystick
 * Returns 0 on success, or -1 if an error occurred.
 */
extern DECLSPEC int SDLCALL SDL_JoystickDetachVirtual(int device_index);

/**
 * Indicates whether or not a virtual-joystick is at a given device index.
 */
extern DECLSPEC SDL_bool SDLCALL SDL_JoystickIsVirtual(int device_index);

/**
 * Set values on an opened, virtual-joystick's controls.
 * Returns 0 on success, -1 on error.
 */
extern DECLSPEC int SDLCALL SDL_JoystickSetVirtualAxis(SDL_Joystick * joystick, int axis, Sint16 value);
extern DECLSPEC int SDLCALL SDL_JoystickSetVirtualBall(SDL_Joystick * joystick, int ball, Sint16 xrel, Sint16 yrel);
extern DECLSPEC int SDLCALL SDL_JoystickSetVirtualButton(SDL_Joystick * joystick, int button, Uint8 value);
extern DECLSPEC int SDLCALL SDL_JoystickSetVirtualHat(SDL_Joystick * joystick, int hat, Uint8 value);

------------------------------------------------------------

Miscellaneous notes on the initial patch, which are also subject to change:

1. no test code is present in SDL, yet.  This should, perhaps, change.  Initial development was done with an ImGui-based app, which potentially is too thick for use in SDL-official.  If tests are to be added, what kind of tests?  Automated?  Graphical?

2. virtual game controllers can be created by calling SDL_JoystickAttachVirtual with a joystick-type of SDL_JOYSTICK_TYPE_GAME_CONTROLLER, with naxes (num axes) set to SDL_CONTROLLER_AXIS_MAX, and with nbuttons (num buttons) set to SDL_CONTROLLER_BUTTON_MAX.  When updating their state, values of type SDL_GameControllerAxis or SDL_GameControllerButton can be casted to an int and used for the control-index (in calls to SDL_JoystickSetVirtual* functions).

3. virtual joysticks' guids are mostly all-zeros with the exception of the last two bytes, the first of which is a 'v', to indicate that the guid is a virtual one, and the second of which is a SDL_JoystickType that has been converted into a Uint8.

4. virtual joysticks are ONLY turned into virtual game-controllers if and when their joystick-type is set to SDL_JOYSTICK_TYPE_GAMECONTROLLER.  This is controlled by having SDL's default list of game-controllers have a single entry for a virtual game controller (of guid, "00000000000000000000000000007601", which is subject to the guid-encoding described above).

5. regarding having to call SDL_JoystickUpdate, either directly or indirectly via SDL_PumpEvents or SDL_PollEvents, before new virtual-joystick state becomes active (as specified via SDL_JoystickSetVirtual* function-calls), this was done to match behavior found in SDL's other joystick drivers, almost all of which will only update SDL-state during SDL_JoystickUpdate.

6. the initial patch is based off of SDL 2.0.12

7. the virtual joystick subsystem is disabled by default.  It should be possible to enable it by building with SDL_JOYSTICK_VIRTUAL=1

David Ludwig b13c951cca CMake: iOS support added
When using a recent version of CMake (3.14+), this should make it possible to:
- build SDL for iOS, both static and dynamic
- build SDL test apps (as iOS .app bundles)
- generate a working SDL_config.h for iOS (using SDL_config.h.cmake as a basis)

To use, set the following CMake variables when running CMake's configuration stage:
- CMAKE_SYSTEM_NAME=iOS
- CMAKE_OSX_SYSROOT=<SDK>  (examples: iphoneos, iphonesimulator, iphoneos12.4, /full/path/to/iPhoneOS.sdk, etc.)
- CMAKE_OSX_ARCHITECTURES=<semicolon-separated list of CPU architectures> (example: "arm64;armv7s")

Examples:
- for Simulator, using the latest, installed SDK:
    cmake path/to/SDL -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphonesimulator -DCMAKE_OSX_ARCHITECTURES=x86_64

- for Device, using the latest, installed SDK, 64-bit only
    cmake path/to/SDL -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphoneos -DCMAKE_OSX_ARCHITECTURES=arm64

- for Device, using the latest, installed SDK, mixed 32/64 bit
    cmake path/to/SDL -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphoneos -DCMAKE_OSX_ARCHITECTURES="arm64;armv7s"

- for Device, using a specific SDK revision (iOS 12.4, in this example):
    cmake path/to/SDL -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphoneos12.4 -DCMAKE_OSX_ARCHITECTURES=arm64

- for Simulator, using the latest, installed SDK, and building SDL test apps (as .app bundles):
    cmake path/to/SDL -DSDL_TEST=1 -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphonesimulator -DCMAKE_OSX_ARCHITECTURES=x86_64

Callum McGing

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.
