run-time + libraries (CRTs). If the executable is linked with a different CRT + from the GLUT DLL, the GLUT DLL will not share the same CRT static + data seen by the executable. In particular, atexit callbacks registered + in the executable will not be called if GLUT calls its (different) + exit routine). GLUT is typically built with the + "/MD" option (the CRT with multithreading DLL support), but the Visual + C++ linker default is "/ML" (the single threaded CRT). + + One workaround to this issue is requiring users to always link with + the same CRT as GLUT is compiled with. That requires users supply a + non-standard option. GLUT 3.7 has its own built-in workaround where + the executable's "exit" function pointer is covertly passed to GLUT. + GLUT then calls the executable's exit function pointer to ensure that + any "atexit" calls registered by the application are called if GLUT + needs to exit. + + Note that the __glut*WithExit routines should NEVER be called directly. + To avoid the atexit workaround, #define GLUT_DISABLE_ATEXIT_HACK. */ + +/* to get the prototype for exit() */ +#include <stdlib.h> + +#if defined(_WIN32) && !defined(GLUT_DISABLE_ATEXIT_HACK) && !defined(__WATCOMC__) +FGAPI void FGAPIENTRY __glutInitWithExit(int *argcp, char **argv, void (__cdecl *exitfunc)(int)); +FGAPI int FGAPIENTRY __glutCreateWindowWithExit(const char *title, void (__cdecl *exitfunc)(int)); +FGAPI int FGAPIENTRY __glutCreateMenuWithExit(void (* func)(int), void (__cdecl *exitfunc)(int)); +#ifndef FREEGLUT_BUILDING_LIB +#if defined(__GNUC__) +#define FGUNUSED __attribute__((unused)) +#else +#define FGUNUSED +#endif +static void FGAPIENTRY FGUNUSED glutInit_ATEXIT_HACK(int *argcp, char **argv) { __glutInitWithExit(argcp, argv, exit); } +#define glutInit glutInit_ATEXIT_HACK +static int FGAPIENTRY FGUNUSED glutCreateWindow_ATEXIT_HACK(const char *title) { return __glutCreateWindowWithExit(title, exit); } +#define glutCreateWindow glutCreateWindow_ATEXIT_HACK +static int FGAPIENTRY FGUNUSED glutCreateMenu_ATEXIT_HACK(void (* func)(int)) { return __glutCreateMenuWithExit(func, exit); } +#define glutCreateMenu glutCreateMenu_ATEXIT_HACK +#endif +#endif + +#ifdef __cplusplus + } +#endif + +/*** END OF FILE ***/ + +#endif /* __FREEGLUT_STD_H__ */ + diff --git a/system/include/GL/glut.h b/system/include/GL/glut.h new file mode 100644 index 00000000..6191f77b --- /dev/null +++ b/system/include/GL/glut.h @@ -0,0 +1,21 @@ +#ifndef __GLUT_H__ +#define __GLUT_H__ + +/* + * glut.h + * + * The freeglut library include file + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS + * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
