Hi!
According to Laussy Fabrice:
I was few weeks ago wondering about a Borland graphical unit, and Peter answered me about the one of GPC. [...] Is it near compatible with the one of Borland [...] ?
Yes.
Meanwhile I am interested in making some code with graphical output using GPC's unit and GPC itself that would be almost compatible with a Borland compilation (which would require minor changes).
You can surround GPC-specific parts with (*$ifdef __GPC___*) ... (*$else *) ... (*$endif *). Only (*$ifopt ... *) constructs will cause problems since GPC currently does not support (*$ifopt ... *).
The other question is about the availability of the GPC library, where can one find it?
See the DJGPP distribution on your favourite SimTel mirror, directory `v2tk', file `grx22.zip', IIRC. Inside that archive, look out for the keywords "Linux", "bcc2grx", and "bgi2grx".
Also, is it well (at least, somewhat) documented?
No, but since you know Borland's `Graph' Unit you won't need that kind of documentation. ;-)
Good luck,
Peter
