Hi,
I've been able to get Direct X 7 working with C++ builder 3 in
windows. I'm having some real trouble getting Open GL development
working with Kylix in Linux. Using the GLUT lib available from SGI
downloaded from Redhat I compiled my code in Kylix. Here is the
probelm, it doens't do anything. I used the same code as what is in the
Open GL super bible second edition. Here is a paste of the code:
//------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
#include <GL/glut.h>

void scene(void){

glClear(GL_COLOR_BUFFER_BIT);

glColor3f(1.0f,0.0f,0.0f);
glRectf(100.0f,150.0f,150.0f,100.0f);
glFlush();
}

void ChangeSize(GLsizei w,GLsizei h){
if(h == 0){
h = 1;
}

glViewport(0,0,w,h);

glMatrixMode(GL_PROJECTION);
glLoadIdentity();

if(w <= h)
glOrtho(0.0f,250.0f,0.0f,250.0f*h/w,1.0, -1.0);
else
glOrtho(0.0f,250.0f*w/h,0.0f,250.0f, 1.0, -1.0);

glMatrixMode(GL_MODELVIEW);
glLoadIdentity();

}

void setupRc(void){
glClearColor(0.0f,0.0f,1.0f,1.0f);
}

void main(void)
{
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
glutCreateWindow("GL Rect");
glutDisplayFunc(scene);
glutReshapeFunc(ChangeSize);

setupRc();

glutMainLoop();
}
//---------------------------------------------------------------------------
When I attempt to run the binary generated here is the message I get:
relocation error: /usr/lib/libglut.so.3 undefined symbol:
XmuLookupStandardColormap
I have an e-machine with an intel810 onboard video card.
I s my system not compliant with OpenGL? Has anyone had any luck with
developing with Kylix and openGL?

I've gotten this working now. I've seen articles on the Borland
community web site about how to setup a OpenGL shell in C++ builder in
windows. I'm going to start by using GLUT, but does anyone have the
same type of sample code for Linux?

Thanks,

Dan Hughes
