# SDL_PLATFORM_LINUX A preprocessor macro that is only defined if compiling for Linux. ## Header File Defined in [<SDL3/SDL_platform_defines.h>](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_platform_defines.h) ## Syntax ```c #define SDL_PLATFORM_LINUX 1 ``` ## Remarks Note that Android, although ostensibly a Linux-based system, will not define this. It defines [SDL_PLATFORM_ANDROID](SDL_PLATFORM_ANDROID) instead. ## Version This macro is available since SDL 3.2.0. ---- [CategoryAPI](CategoryAPI), [CategoryAPIMacro](CategoryAPIMacro), [CategoryPlatform](CategoryPlatform)
