Hi Ivan,

I followed your guide line and writed a simple program in C to load a Ima=
ge.

In attach goes the program and the output.

I think i'm having real problems here because it crashes before anything
is done.

Can you see if this error is known to you?

Many thx,

Nuno

Re: [sdljava-users] sdljava-users Digest, Vol 1, Issue 161

[Ivan Z. G. <iva...@ya...>]

Really sorry this isn't working for you.  Unfortunatly I don't have a 
system up yet where I can develop.  I have not been able to compile SDL 
yet under my 32 bit chroot.  Working on it but time is scarce.  So I'm 
not able to test...

I noticed in the output your using the framebuffer device.  I never 
tested with this myself.  It should work though if SDL supports it, but, 
I never did try.

Searching on Google I found this, maybe it will help you:
    http://mail.directfb.org/pipermail/directfb-users/2005-April/000121.html

When you display the image that has strange colors is this also on the 
FB device?  Perhaps we have a problem there...
