Mesa-Glut compilation problem


OK I should use a makefile, but my first attempt at using mesa on a simple
Hello.cpp programme using



icc -static -o Hello Hello.cpp -L/usr/X11R6/lib -lX11 -lglut -lMesaGL -lMesaGLU -lXext -lm -lXmu


gives me a huge list of errors like

/usr/lib/libglut.a (glut event.o) glah blah
:undefined reference to function `Xflush'

As far as I can see I have all the libraries I need, I find Xflush is a basic Xlib function, but should -lX11 see to that?

#include <GL/gl.h>
#include <GL/glut.h>


/* Called when window needs to be redrawn */
void redraw()
{
glClear(GL_COLOR_BUFFER_BIT); /* clear screen to black */
/* just draw a boring red triangle */
glBegin(GL_TRIANGLES);
glColor3f(1.f, 0.f, 0.f);
glVertex2f(-.5f, -.5f);
glVertex2f( .5f, -.5f);
glVertex2f( 0.f, .5f);
glEnd();
glFlush();
}

/* Parse arguments, and set up interface between OpenGL and window system */
main(int argc, char *argv[])
{
glutInit(&argc, argv);
glutInitWindowSize(512, 512);
glutInitDisplayMode(GLUT_RGBA);
(void)glutCreateWindow("simple program");
glutDisplayFunc(redraw);
glutMainLoop();
}

try putting the -o at the end. gcc and g++ sometimes do wierd things regarding specification of libraries and library paths if your -o comes first.

that's all I can think of.
