Building DVSDK against an external kernel

I'm trying to build DVSDK 04.00.03.06 against a kernel from the gumstix git source. The kernel boots fine, and i've been able to build and load dsplink, cmem, and lpm. Now i'm trying to build DMAI (2.20.00.15) against these packages, but i'm getting an error.

For a little background, what i'm trying to accomplish is an accelerated JPEG encoder.

I'm kind of stuck. How should i proceed from here?

    OK. Turns out that some of the "Capture" components in the dvsdk fouled up the build. I removed them.

    The DVSDK Is now building against my kernel, and the dsplink demos (messagegpp, loopgpp, etc) are working!

    Now i need to abstract the JPEGENC interface so it will work for my application. In codecs-omap3530_4_02_00_00 there seems to be a jpegenc test application; 'make codecs' from the dvsdk install dir doesn't seem to build them. How do I go about doing this?

    Thanks,
