can you send me the code of your program?
or a tutorial?
I am going to do a game, so I need load a sprite from a pcx with svgalib.

DO NOT USE SVGALIB. It''s unsafe, unstable and dead as far as libraries go. It''s an exploit waiting to happen. Use the FrameBuffer or *anything* else.
Right. Use SDL (www.libsdl.org).

svgalib is unsafe and usntable? how so?
not trying to pick a fight, but I use a couple svgalib progs, I want to know if and how svgalib is compromising my system. I don''t think its unstable.. no crashes on any of my linux systems.

Just as anything else svgalib is a security risk when used improperly. The thing on my mind is that svgalib programs must be run suid/sgid root - although when you call vga_init() it changes the uid/gid to that of non-root, and thus eleminating a vast security hole. Therefore you should always call vga_init() right after you open the main function.
I''m sure there are plenty of other security holes in there but that''s the only one I know of

I have.. to date.. seen a ton of svgalib programs. Without going into detail.. I have a 100% record of ending up rooting the box with the program set suid/guid root. 100%. It''s unsafe to use svgalib. I would recommend using sdl and allowing users to compile for whatever target they want.. but I''d stick with X11 myself.. or mebbe framebuffer.

I''ve heard the new version of svgalib does not require root privileges to run.

The only way it cannot require root is to use the framebuffer device, which is often worse than using X11. The graphics are scaled down and back immensely. SvgaLib is dated and insecure. I''ve been using and programming in Linux for five years now. Trust me on this one .
