From dc2919d57ba9dd7cea9a525edf37e9b4398b8816 Mon Sep 17 00:00:00 2001 From: Riteo Siuga Date: Sat, 12 Nov 2022 21:46:16 +0100 Subject: Load GLX dynamically with GLAD This is accomplished through the addition of a GLAD GLX loader in the `thirdparty` directory. This is another step towards a nice Wayland/X11 interoperation. --- thirdparty/README.md | 2 + thirdparty/glad/glad/glx.h | 605 +++++++++++++++++++++++++++++++++++++++++++++ thirdparty/glad/glx.c | 395 +++++++++++++++++++++++++++++ 3 files changed, 1002 insertions(+) create mode 100644 thirdparty/glad/glad/glx.h create mode 100644 thirdparty/glad/glx.c (limited to 'thirdparty') diff --git a/thirdparty/README.md b/thirdparty/README.md index 2dced503a8..f167ab5974 100644 --- a/thirdparty/README.md +++ b/thirdparty/README.md @@ -186,6 +186,8 @@ Files generated from [upstream web instance](https://gen.glad.sh/): - `KHR/khrplatform.h` - `gl.c` - `glad/gl.h` +- `glx.c` +- `glad/glx.h` ## glslang diff --git a/thirdparty/glad/glad/glx.h b/thirdparty/glad/glad/glx.h new file mode 100644 index 0000000000..ac115fa63b --- /dev/null +++ b/thirdparty/glad/glad/glx.h @@ -0,0 +1,605 @@ +/** + * Loader generated by glad 2.0.2 on Tue Nov 15 09:49:49 2022 + * + * SPDX-License-Identifier: (WTFPL OR CC0-1.0) AND Apache-2.0 + * + * Generator: C/C++ + * Specification: glx + * Extensions: 6 + * + * APIs: + * - glx=1.4 + * + * Options: + * - ALIAS = False + * - DEBUG = False + * - HEADER_ONLY = False + * - LOADER = True + * - MX = False + * - ON_DEMAND = False + * + * Commandline: + * --api='glx=1.4' --extensions='GLX_ARB_create_context,GLX_ARB_create_context_profile,GLX_ARB_get_proc_address,GLX_EXT_swap_control,GLX_MESA_swap_control,GLX_SGI_swap_control' c --loader + * + * Online: + * http://glad.sh/#api=glx%3D1.4&extensions=GLX_ARB_create_context%2CGLX_ARB_create_context_profile%2CGLX_ARB_get_proc_address%2CGLX_EXT_swap_control%2CGLX_MESA_swap_control%2CGLX_SGI_swap_control&generator=c&options=LOADER + * + */ + +#ifndef GLAD_GLX_H_ +#define GLAD_GLX_H_ + +#ifdef GLX_H + #error GLX header already included (API: glx), remove previous include! +#endif +#define GLX_H 1 + + +#include +#include +#include + +#include + +#define GLAD_GLX +#define GLAD_OPTION_GLX_LOADER + +#ifdef __cplusplus +extern "C" { +#endif + +#ifndef GLAD_PLATFORM_H_ +#define GLAD_PLATFORM_H_ + +#ifndef GLAD_PLATFORM_WIN32 + #if defined(_WIN32) || defined(__WIN32__) || defined(WIN32) || defined(__MINGW32__) + #define GLAD_PLATFORM_WIN32 1 + #else + #define GLAD_PLATFORM_WIN32 0 + #endif +#endif + +#ifndef GLAD_PLATFORM_APPLE + #ifdef __APPLE__ + #define GLAD_PLATFORM_APPLE 1 + #else + #define GLAD_PLATFORM_APPLE 0 + #endif +#endif + +#ifndef GLAD_PLATFORM_EMSCRIPTEN + #ifdef __EMSCRIPTEN__ + #define GLAD_PLATFORM_EMSCRIPTEN 1 + #else + #define GLAD_PLATFORM_EMSCRIPTEN 0 + #endif +#endif + +#ifndef GLAD_PLATFORM_UWP + #if defined(_MSC_VER) && !defined(GLAD_INTERNAL_HAVE_WINAPIFAMILY) + #ifdef __has_include + #if __has_include() + #define GLAD_INTERNAL_HAVE_WINAPIFAMILY 1 + #endif + #elif _MSC_VER >= 1700 && !_USING_V110_SDK71_ + #define GLAD_INTERNAL_HAVE_WINAPIFAMILY 1 + #endif + #endif + + #ifdef GLAD_INTERNAL_HAVE_WINAPIFAMILY + #include + #if !WINAPI_FAMILY_PARTITION(WINAPI_PARTITION_DESKTOP) && WINAPI_FAMILY_PARTITION(WINAPI_PARTITION_APP) + #define GLAD_PLATFORM_UWP 1 + #endif + #endif + + #ifndef GLAD_PLATFORM_UWP + #define GLAD_PLATFORM_UWP 0 + #endif +#endif + +#ifdef __GNUC__ + #define GLAD_GNUC_EXTENSION __extension__ +#else + #define GLAD_GNUC_EXTENSION +#endif + +#define GLAD_UNUSED(x) (void)(x) + +#ifndef GLAD_API_CALL + #if defined(GLAD_API_CALL_EXPORT) + #if GLAD_PLATFORM_WIN32 || defined(__CYGWIN__) + #if defined(GLAD_API_CALL_EXPORT_BUILD) + #if defined(__GNUC__) + #define GLAD_API_CALL __attribute__ ((dllexport)) extern + #else + #define GLAD_API_CALL __declspec(dllexport) extern + #endif + #else + #if defined(__GNUC__) + #define GLAD_API_CALL __attribute__ ((dllimport)) extern + #else + #define GLAD_API_CALL __declspec(dllimport) extern + #endif + #endif + #elif defined(__GNUC__) && defined(GLAD_API_CALL_EXPORT_BUILD) + #define GLAD_API_CALL __attribute__ ((visibility ("default"))) extern + #else + #define GLAD_API_CALL extern + #endif + #else + #define GLAD_API_CALL extern + #endif +#endif + +#ifdef APIENTRY + #define GLAD_API_PTR APIENTRY +#elif GLAD_PLATFORM_WIN32 + #define GLAD_API_PTR __stdcall +#else + #define GLAD_API_PTR +#endif + +#ifndef GLAPI +#define GLAPI GLAD_API_CALL +#endif + +#ifndef GLAPIENTRY +#define GLAPIENTRY GLAD_API_PTR +#endif + +#define GLAD_MAKE_VERSION(major, minor) (major * 10000 + minor) +#define GLAD_VERSION_MAJOR(version) (version / 10000) +#define GLAD_VERSION_MINOR(version) (version % 10000) + +#define GLAD_GENERATOR_VERSION "2.0.2" + +typedef void (*GLADapiproc)(void);
