There is a several bug in the unit inicialization code which afect more units not only Graph. Look at this bugreport: http://www.freepascal.org/mantis/view.php?id=7338
You could to try use my modified unit Graph http://www.laaca.borec.cz/graph.zip which works for me but the inicialization bug in FPC 2.0.4 makes this compiler virtualy unusable. ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <fpc-devel@lists.freepascal.org> Sent: Monday, September 11, 2006 12:00 PM Subject: fpc-devel Digest, Vol 25, Issue 17 > Send fpc-devel mailing list submissions to > fpc-devel@lists.freepascal.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.freepascal.org/mailman/listinfo/fpc-devel > or, via email, send a message with subject or body 'help' to > [EMAIL PROTECTED] > > You can reach the person managing the list at > [EMAIL PROTECTED] > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of fpc-devel digest..." > > > Today's Topics: > > 1.
