I don't know, but it already worked on the older versions of fpc (before
2.0.0) on Mac OS X 10.3 Panther quite nice and without any errors.
The error message i do now get on the console (after the program crashes) is
the following:
An unhandled exception occurred at $903E68B8 :
EInvalidOp : Invalid floating point operation
$903E68B8
$945772A0

So it first seems to be some error in the fpu code generation of the
compiler. But the strange things is, after running a C-Program which uses
glut and open gl everything just works fine. So maybe there is something
wrong in the open gl / glut initialization part or some incompatibilities
with Mac OS X 10.4
Here's a very minimalistic fpc opengl glut program which produces the error
from above:
Program Tutor01;
Uses GL, GLUT;
Procedure reshape(width, height : longint); CDecl;
Var aspect : glFloat;
Begin
glViewport(0, 0, width, height); //change viewport to complete window
if height <= 0 then height := 1; // just to be sure that there will be no
division by zero
glMatrixMode(GL_PROJECTION); //I want to change the projection matrix
glLoadIdentity; //First load the identity matrix
aspect := width / height; //calculate the aspect ratio
glFrustum(-1.0*aspect, 1.0*aspect, 1.0, -1.0, 1.0, 20.0); //and produce
our viewing space
glMatrixMode(GL_MODELVIEW); //someone might want to change the
viewing matrix, so switch back
glLoadIdentity; //load the identity matrix
glutPostRedisplay; //tell GLUT we want to draw
End;
Procedure draw; CDecl;
Begin
glClear(GL_COLOR_BUFFER_BIT); //clear the screen or window
glBegin(GL_QUADS); //we want to draw a QUAD
glVertex3f(-0.5, -0.5, -2.0); //top-left corner
glVertex3f(-0.5, 0.5, -2.0); //bottom-left corner
glVertex3f( 0.5, 0.5, -2.0); //bottom-right corner
glVertex3f( 0.5, -0.5, -2.0); //top-right what, yes, corner
glEnd;
glFlush; //tell OpenGL is should empty its command buffer
(execute all commands)
glutSwapBuffers; //tell GLUT to actually show the nice white
square
End;
Begin
glutInit(@argc, argv); //let GLUT do some initialization
glutInitDisplayMode(GLUT_RGB or GLUT_DOUBLE); //make the window highcolor,
double buffered
glutCreateWindow('Tutorial 01'); //now create the first window
glutDisplayFunc(@draw); //register callback functions
glutReshapeFunc(@reshape);
glutMainLoop; //and now actually run
End.
After running the program i get the following error report from Mac OS:

I will try to run this on Mac OS X 10.3 to see what happens there, will try
to build a snapshot version of the fpc compiler (with olle's help) but if
anybody has some idea why this does not work, i would be happy to hear about
it.
Thanks for your help.
