[blabla]..........[/blabla]
j'ai un probleme de débutant j'ai voulu tester un programme basique dont le code provient d'un bouqin
c'est censé faire tourner un carré...
le code est le suivant
Code :
- #include <stdlib.h>
- #include <GL/gl.h>
- #include <GL/glut.h>
- static GLfloat spin = 0.0;
- void init(void)
- {
- glClearColor(0.0, 0.0, 0.0, 0.0);
- glShadeModel(GL_FLAT);
- }
- void display(void)
- {
- glClear(GL_COLOR_BUFFER_BIT);
- glPushMatrix();
- glRotatef(spin, 0.0, 0.0, 1.0);
- glColor3f(1.0 , 1.0, 1.0);
- glRectf( -25.0, -25.0, 25.0, 25.0);
- glPopMatrix();
- glutSwapBuffers();
- }
- void spinDisplay(void)
- {
- spin = spin +2.0;
- if(spin < 360.0){
- spin = spin -360.0;
- }
- glutPostRedisplay();
- }
- void reshape(int w, int h)
- {
- glViewport(0, 0, (GLsizei) w, (GLsizei)h);
- glMatrixMode(GL_PROJECTION);
- glLoadIdentity();
- glOrtho( -50.0, 50.0, -50.0, 50.0, -1.0, 1.0);
- glMatrixMode(GL_MODELVIEW);
- glLoadIdentity();
- }
- void mouse(int button , int state, int x, int y)
- {
- switch(button){
- case GLUT_LEFT_BUTTON:
- if(state == GLUT_DOWN)
- glutIdleFunc(spinDisplay);
- break;
- case GLUT_MIDDLE_BUTTON:
- if(state == GLUT_DOWN)
- glutIdleFunc(NULL);
- break;
- default:
- break;
- }
- }
- int main(int argc, char** argv)
- {
- glutInit(&argc, argv);
- glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB);
- glutInitWindowSize(250, 250);
- glutInitWindowPosition(100, 100);
- glutCreateWindow(argv[0]);
- init();
- glutDisplayFunc(display);
- glutReshapeFunc(reshape);
- glutMouseFunc(mouse);
- glutMainLoop();
- return 0;
- }

et pour le makefile
Code :
- but : opengl
- double.o : double.cc
- g++ -c double.cc
- opengl : double.o
- g++ double.o -o prog

le code est bon ca compile le fichier .o mais jobtiens

j'ai essayé de rajouter des arguments du genre "-lgl -lglu -lglut -lm -lX11" a la commande qui compile mais elle ne l'est trouve pas
merci d'avance de maider ca doit pas etre bien dur mais bon ca bloque tout :s
