Vorbis - May 2009 - Regarding cross compiling of ogg vordis decoder to arm board

Hi,
Tis is kiran. I ve a project  in which v have to cross compile the source
code of ogg vorbis audio decoder onto EDB9302 ARM board..
Can u pls tell me the steps how to proceed or lead me to a source whr i can
find the procedure...


Thank u

Hello,

I d not know the details of this particular ARM board, so there are
several potential starting points.  Nor have you said what toolchain
you would prefer to use; we will likely only be able to help with a
GCC-based toolset.

If you are using an FPU-less or very memory constrained ARM, you will
want to use the Tremor source base.  There are three main Tremor
versions; one is a general purpose implementation for CPUs with access
to large offboard memory, the second is a low-memory version of the
first (it requires more MIPS, but vastly less memory), and the third
is a version of the low-memory code for CPUs without byte addressing.
You probably want one of the first two.

The three branches are available through SVN from:
http://svn.xiph.org/trunk/Tremor (low CPU / high memory)
http://svn.xiph.org/branches/lowmem-branch (high CPU / low memory)
http://svn.xiph.org/branches/lowmem-no-byte (high CPU / low memory/ no
byte addressing)
