David Gow	e87184b502	Fix the OpenGL backends on non-glx Linux platforms (and remove GLEW dependency) (#446) ... * Work around issues with depth-buffer size on EGL-based platforms The OpenGL 1.1 and OpenGL ES 2.0 backends can break on EGL-based platforms, such as Wayland, or X11 with SDL_VIDEO_FORCE_EGL=1. One of the reasons for this (the other being glew on the GL1.1 backend) is that SDL/egl get very confused by the way we set OpenGL attributes, particularly SDL_GL_DEPTH_SIZE, resulting in SDL_GL_CreateContext() failing with EGL_BAD_MATCH. The exact cause of this is unknown, but it seems to be a combination of: - SDL_GL_SetAttribute() is supposed to be called _before_ the window is created, and we're calling it afterward. - Creating several test windows during the enumeration process, mixing and matching between OpenGL and OpenGL ES profiles. The "most correct" solution is probably to delay creating the game window until the backend creation process, rather than before the enumeration occurs. But that's a real refactor, which could cause other issues. Instead, set the 24-bit bit depth (which we've hardcoded anyway) before creating the window, and use SDL_GL_ResetAttributes() when creating backends. This seems to work here in all of the cases I was able to try (modulo the GLEW dependency, which is removed in the next patch). * miniwin: Remove GLEW dependency for OpenGL 1.1 GLEW normally backs directly onto glXGetProcAddress on Linux, which is broken on non-GLX setups, such as Wayland (but also X11 with EGL, and presumably KMSDRM). Replace it with manual calls to SDL_GL_GetProcAddress() for the VBO path. Note, however, that SDL_opengl.h includes "windows.h", so conflicts with the miniwin implementation, which breaks builds on windows. In order to work around this, we do what the Direct3D9 implementation does and push all of the OpenGL calls to a separate file, actual.cpp. Going forward, it may make sense to load _all_ OpenGL entry points via SDL, which would allow us to avoid linking directly with libGL/libOpenGL, and therefore eliminate the separate build dependency altogether, as well as allowing more runtime configurability as to the OpenGL library to load. (But that's definitely a bit uglier, and also useful very rarely.)	2025-06-29 17:47:09 +02:00
