Problems of buliding codec engine examples

Resend due to bounce.

If you have purchased the DVEVM, then you can access all of the content
with the exception of the c6x+ compiler from www.ti.com/dvevmupdates.

>From the message below, it looks like you have access to v1.10 - please
be advised you should update to the u-boot provided with the 1.10.01
release as this fixes a problem where the DSP power is not properly
enabled by u-boot in v1.10.

You can purchase the DVSDK-L and get a full license to MontaVista Linux
and access to the c6x+ compiler or you can purchase CCS 3.3 to get
access to the c6x+ compiler.

You need at least DVSDK, the codec packages, and the server build
scripts.  I don't know the details on how you obtain those pieces, but
others on this list and/or your TI rep can help.
