hi all in the mailing list ;)
i'm here to ask you some questions because there's a thing i cannot deal with. i've written a cool little game for DOS with BGI drivers. (it's a kinda GNibbles)
the thing is that i've done it for DOS & BGI just because i didn't know how to deal with graphics under Linux and *possibly* the X Window System.
as a beginner, i'd like to get something that can compile the program under linux wrapping BGI calls to Svgalib calls or something similar. and i heard of BGI2GRX, but it's not clear for me what it really does.
my aim is to deal with graphics first outside X, then i'd like to use X and Gtk (wrapping C functions with appropriate definitions)
... please light my way ...
thanks in advance again,

BGI2GRX is exactly what you are looking for: A BGI wrapper to a portable graphics library, GRX, that can work on top of SVGAlib or X11 (or plain VGA or (in development) the Win32 API). Please install BGI2GRX and GRX, and just proceed.

We do not currently have a ready-to-use interface to Gtk, but such a thing is straightforward to write (while certainly some work). If you do so, please let us know ...
Greetings,
Peter

ok now... i got grx-2.3 from gnu.de ftp site. i compiled it linking it with svgalib, and it seems to be ok. i added this to global /etc/profile (as written in the webpage):
export GRX20DRV='svgalib gw 640 gh 480 nc 16' export GRX20FNT=/usr/src/grx-2.3/fonts
now, bgi2grx.pas doen't seem to compile. this is what i get:

one more time i have to hope in your help,
i promise when i am able to help people with problems like these, i'll help them for you.
