I found out how to compile the cl when I checked the code too
But maybe Linux driver issue or so, I cannot compile the kernel.
Using device 0 as GPU 0
Using device 1 as GPU 1
Compiling ...

Actually I tried eXtremal's original open source miner too and never compile right neither.
He said AMD SDK is buggy and I used ATI driver compiler but still not successful.
I've found subtle solution if you have more than 1 card.
Disable all BUT 1 card in config.txt. Run xpmminer. kernel.bin is created. Shut down miner. Undo changes in config. Run with normal config.
Works for me.
