Hello
I played around with the OpenGL unit, and I wrote some minimal OpenGL code to get a
window:
Here is the code:
program glbasic;
uses
gl, glut;
const
width = 640;
height= 480;
procedure drawthings;
begin
glClearColor(0.0, 0.0, 0.0, 0.0);
(*will add some more code*);
end;
begin
glutInit(@argc, argv);
glutInitDisplayMode(GLUT_DOUBLE or GLUT_RGB);
glutInitWindowSize( width, height);
glutInitWindowPosition(0, 0);
glutCreateWindow('glbasic');
glutDisplayFunc(@drawthings);
glutMainLoop();
end.
Now, when I whant to run to code, I get some Run time errors on the console:
Runtime error 216 at 0x4052F5CA
0x4051F5CA
Runtime error 216 at 0x0804C1CA
0x0849C1CA
0x0805127E
etc.
etc.
etc. (about 20 lines)
1). I know not a lot of runtime errors, but after succesfully compiling, that isn`t a
fpc bug, is it ?
What is the source of this run time error ? (mesa, fpc or my code ?)
2). I think about there isn`t enough code in the drawthings procedure to run
succesfull.
What you think ?
Greetings
Karim F.
