SDL with OpenGL (freeglut) crashes on call to glutBitmapCharacter
- by stett
I have a program using OpenGL through freeglut under SDL. The SDL/OpenGL initialization is as follows:
// Initialize SDL
SDL_Init(SDL_INIT_VIDEO);
// Create the SDL window
SDL_SetVideoMode(SCREEN_W, SCREEN_H, SCREEN_DEPTH, SDL_OPENGL);
// Initialize OpenGL
glClearColor(BG_COLOR_R, BG_COLOR_G, BG_COLOR_B, 1.f);
glViewport(0, 0, SCREEN_W, SCREEN_H);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(0.0f, SCREEN_W, SCREEN_H, 0.0f, -1.0f, 1.0f);
glEnable(GL_TEXTURE_2D);
glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
I've been using glBegin() ... glEnd() blocks without any trouble to draw primitives. However, in this program when I call any glutBitmapX function, the program simply exits without an error status. The code I'm using to draw text is:
glColor3f(1.f, 1.f, 1.f);
glRasterPos2f(x, y);
glutStrokeString(GLUT_BITMAP_8_BY_13, (const unsigned char*)"test string");
In previous similar programs I've used glutBitmapCharacter and glutStrokeString to draw text and it's seemed to work. The only difference being that I'm using freeglut with SDL now instead of just GLUT as I did in previous programs. Is there some fundamental problem with my setup that I'm not seeing, or is there a better way of drawing text?
