Re: [Mesa3d-users] Mesa compilation using EABI toolchain

[iluvlinux <ilu...@gm...>]

EABI toolchain is new toolchain provided by ARM 
http://wiki.debian.org/ArmEabiPort http://wiki.debian.org/ArmEabiPort 

and clutter is a library that provides simple apis to users who don't know
about opengl and related stuff
http://clutter-project.org/ http://clutter-project.org/ 


I did a hexdump of some test images in totally red, or green or blue color,
and i found that the pixel values were accurate according to the images. I
have no idea were to look into mesa code. i did hexdump in clutter code just
before it calls glTexImage2D.


Here are some information related to EABI todo list
http://wiki.debian.org/ArmEabiTodo http://wiki.debian.org/ArmEabiTodo 


i have no idea about how to compile mesa with some different options ,all i
did to compile mesa is to type "make linux" and it builds cleanly.

if you could just help me out by providing some compile options if needed
with the new tool chain, i would be highly thankful to you. I know i am
asking something that is very difficult.

kindly help


thanks for your reply
