color issues

[mad_muppet]

I wrote a mandelbrot set program a while back and just lately I revisited it. it compiles fine on both windows xp and debian lenny and runs on both ..

however I only get color on xp .. black and white for lenny ..

so I copied one of my screenshots over from xp to lenny and it was in color ..

I copied one of my screenshots from lenny over just to check and it was in black and white ..

I went to #debian on freenode and had a chat and one of the guys suggested that it was a software problem ..

personally I dont know but any help or pointers in the right direction appreciated

thanks al.

ps not sure how to attach a file but the program is at C | /* draw mandelbrot set and res - Anonymous - J7LVtP46 - Pastebin.com

That's odd, seems to work fine for me. On Arch Linux...

And there's nothing that stuck out as wrong in the code. Other than the abuse of global variables

It was purple and black for me (FC10-64). I was going to take a screen shot, but the second time I clicked the mouse:

main
set_sdl
lock_screen
real_imaginary
unlock_screen
1 ) mousebutton_event z = 1
374 250 0 0
2 ) mousebutton_event z = 2
374 250 374 250
s = -0.720643
t = 0.000000
u = -0.720643
v = 0.000000
ximage = 0.000000
yimage = 0.000000
xoff = 0.720643
yoff 0.000000
Floating point exception

I would work in openGL with SDL for 2D stuff -- it would be quite a bit faster. I think even the SDL developers recommend this.

thanks for the replies ..

I know I had it running correctly before on linux .. it does work ok on xp ..

the program is designed to work left high click to low right click .. not sure if thats what caused it to crash ..
