Just installed the DVSDK 4 beta and a make failed after entering the psp directory with the following error....
make -C /home/john/dm368/dvsdk_4_00_00_17/psp/linux-kernel-source ARCH=arm CROSS_COMPILE=/home/john/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi- davinci_dm365_defconfig
make[1]: Entering directory `/home/john/dm368/dvsdk_4_00_00_17/psp/linux-kernel-source'
Makefile:202: *** CROSS_COMPILE changed from "arm-none-linux-gnueabi-" to to "/home/john/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-". Use "make mrproper" to fix it up. Stop.
I should mention that I configured the kernel and built it before I realized that the DVSDK make file was going to do that. But I don't see how that would cause this error.
Also there is no CROSS_COMPILE in the environment before the make is invoked. The build previous to that runs fine and the CodeSourcery is in the location noted in the listing.
Thanks,
John A.
