fe6f62e6	2021-02-10T15:17:02	Add ALIAS targets to all installed SDL2 targets This provides a linking interface that matches the one available when `find_package()` is used, by aliasing all of SDL's public targets into the SDL2:: namespace. Thus, dependees link to the same-named targets regardless of how SDL was acquired. This approach permits the use of wrappers around CMake's FetchContent API such as https://github.com/cpm-cmake/CPM.cmake

de1c19b3	2021-01-25T20:43:21	Fixed bug 5481 - iOS-specific main sources not used for CMake build. Aaron Barany The CMake build for SDL doesn't set SDLMAIN_SOURCES on iOS to the sources in src/main/ios. As a result, SDL fails to initialize since it falls back to the dummy main. Adding the line file(GLOB SDLMAIN_SOURCES ${SDL2_SOURCE_DIR}/src/main/uikit/*.c) fixes the issue.

45e3521d	2020-12-09T07:32:10	Backed out changes for 5366 - cmake build doesn't detect Metal on macOS These changes introduce regressions for other build environments, so I'm backing them out until we sort out the correct fix.
479db430	2020-12-09T06:56:34	Fixed bug 5250 - updaterev.sh failed using CMake Tools on VSCode Remote Sebastian Vargas Vargas Running CMake configure from a Windows Subsystem for Linux using Visual Studio Code Remote doesn't generate the header file with the current source revision, it throws "/home/sebva/SDL/build-scripts/updaterev.sh: 13: cannot create /mnt/c/Users/sebva/.vscode/extensions/ms-vscode-remote.remote-wsl-0.44.4/include/SDL_revision.h.new: Directory nonexistent".
42c5b4ac	2020-12-09T06:17:55	Fixed bug 5366 - cmake build doesn't detect Metal on macOS Tom Seddon 2nd time lucky, perhaps. patch 2 applies to current HEAD at time of writing - 4eb049c9bb1ca94efe3c40b57beda3169984d0cb from https://github.com/SDL-mirror/SDL. This basically goes back to what was there originally, but now manually adding "-x objective-c" to the clang command line rather than "-ObjC". clang is then invoked without the "-x c" that was causing the problem, the snippet builds, and Metal is detected. (I had a quick trawl through the cmake code, but I couldn't see where this is handled.) I was moved to try this after finding SDL's own CHECK_OBJC_SOURCE_COMPILES macro, and noting what it does: https://github.com/SDL-mirror/SDL/blob/4eb049c9bb1ca94efe3c40b57beda3169984d0cb/cmake/macros.cmake#L67 An alternative fix of course would be to use CHECK_OBJC_SOURCE_COMPILES instead of cmake's check_objc_source_compiles - but that had the same problem of getting confused by "return 0;". (Maybe that's because it's a macro? I'll defer to a cmake expert on this one.) I decided in the end to err on the side of leaving things looking basically the same as they were before my first patch.

4b35a18d	2020-12-01T13:50:42	Fixed bug 5366 - cmake build doesn't detect Metal on macOS Tom Seddon This is as of commit 50d804ea729accf9e3a9ce83238d0a2976a17545 from https://github.com/SDL-mirror/SDL, which is HEAD as I write (apologies, not confident with Mercurial) # Config macOS: 10.14.6 (18G6042) cmake --version: cmake version 3.16.20200101-g23e782c clang --version: Apple clang version 11.0.0 (clang-1100.0.33.17) Xcode version: Version 11.3.1 (11C504) # Repro steps Run the following commands in the shell. cd /tmp/ git clone https://github.com/SDL-mirror/SDL mkdir build.SDL cd build.SDL cmake -G ../SDL/ Examine cmake output. # Expected result Metal is detected. # Actual result It appears that Metal is not detected! Note this line in the summary: -- RENDER_METAL (Wanted: 0): OFF # Fix Change check_c_source_compiles to check_objc_source_compiles. The cmake script tries to add -ObjC to the clang command line, but, for whatever reason, this doesn't seem to work. Change the test source to have an empty main. The "return 0;" line seems to confuse cmake somehow, causing it to crap out with an error about HAVE_FRAMEWORK_METAL being an unknown argument. (Maybe I'm just dense, but it's not obvious to me what the problem is here.) With these two changes: -- RENDER_METAL (Wanted: ON): ON Patch attached.

a8400dc3	2020-05-29T16:31:05	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.

eadc8693	2020-05-11T14:31:04	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.

abcc6706	2020-04-12T13:24:36	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.
99f87a71	2020-04-11T23:38:34	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.

2be75c6a	2020-03-13T19:08:45	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 Questions, comments, suggestions, or bug reports very welcome!

Fixed bug 5366 - cmake build doesn't detect Metal on macOS Tom Seddon 2nd time lucky, perhaps. patch 2 applies to current HEAD at time of writing - 4eb049c9bb1ca94efe3c40b57beda3169984d0cb from https://github.com/SDL-mirror/SDL. This basically goes back to what was there originally, but now manually adding "-x objective-c" to the clang command line rather than "-ObjC". clang is then invoked without the "-x c" that was causing the problem, the snippet builds, and Metal is detected. (I had a quick trawl through the cmake code, but I couldn't see where this is handled.) I was moved to try this after finding SDL's own CHECK_OBJC_SOURCE_COMPILES macro, and noting what it does: https://github.com/SDL-mirror/SDL/blob/4eb049c9bb1ca94efe3c40b57beda3169984d0cb/cmake/macros.cmake#L67 An alternative fix of course would be to use CHECK_OBJC_SOURCE_COMPILES instead of cmake's check_objc_source_compiles - but that had the same problem of getting confused by "return 0;". (Maybe that's because it's a macro? I'll defer to a cmake expert on this one.) I decided in the end to err on the side of leaving things looking basically the same as they were before my first patch.

The cmake script tries to add -ObjC to the clang command line, but, for whatever reason, this doesn't seem to work. Change the test source to have an empty main. The "return 0;" line seems to confuse cmake somehow, causing it to crap out with an error about HAVE_FRAMEWORK_METAL being an unknown argument. (Maybe I'm just dense, but it's not obvious to me what the problem is here.) With these two changes: -- RENDER_METAL (Wanted: ON): ON Patch attached.

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.

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.

locale: Implemented SDL_GetPreferredLocales(). This was something I proposed a long time ago, Sylvain Becker did additional work on it, then back to me. Fixes Bugzilla #2131.

cmake: use check_symbol_exists, not check_function_exists (thanks, Manuel!) This fixes the problem where we think iOS has fseeko64, etc, but doesn't. Fixes Bugzilla #4885.

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.

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.

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 Questions, comments, suggestions, or bug reports very welcome!
