Hi,

I have a problem in drawing opengl in Gentoo linux, my harware is AMD Geode
board.Its a small intelligent board.This hardware does not support 3D drawings
and GLX commands.

My requirement is I want to draw a simple 2D using normal fltk window,

I did this in windows(OS) in two different methods but the problem is with linux.
1.Get the window handle, Get device context and rendering context,
set pixel format and start drawing.
2.Using glstart() and glFinish().

When I try the above two methods in linux it says the following error.

1.when i use glstart and glfinish along with glVisual, it says "Segmentation fault" in Gentoo linux deskop PC, and XopenIM() fail XLib: Extension "GLX" missing on display ":0.0" Insufficient GL support in Geode board.

I am using gentoo linux in both desktop and geode board.

My fltk version is V2.0.0, gentoo linux kernel version is genkernel-x86-2.6.23-gentoo-r8

I want to run the code in both desktop linux pc and in Geode board PC.

thanks

Hi,

Now i got rid of segmentation fault, but I could not clear the screen using glClearColor, I think the color buffers are not getting cleared.I doubt the rendering context.

awaiting for inputs.

thanks.

Hi,

I made the opengl 2d working in gentoo linux in desktop pc,
but not in my actual hardware.

have anybody tried drawing opengl using normal gl commands
in AMD geode board.

thanks.

hi,

That's the end of the story.

The problem is:
Not able to use glx commands in fltk, due to the following error:

XopenIM() fail XLib: Extension "GLX" missing on display ":0.0" Insufficient GL support

The solution is:

Download MesaLib-7.0.3.tar from http://sourceforge.net/project/showfiles.php?group_id=3

make install, you will get the library files like

libgl.so.1 etc., and place it in usr/lib.

And also download libglx.so(actually i had his file in my desktop pc) and place it in user/lib.

Thanks.
