I've been cross compiling compat-wireless and now I'm trying

compat-wireless......
Learned some things....Problem was LTIB (ltib = Freescale tool)
environment. Outside of LTIB, backports cross compiles fine. To get
backports happy in LTIB need to use UNSPOOF/SPOOF_PATH to switch between
host and cross environment....
%Build
export PATH=$UNSPOOF_PATH

Howdy. :)
(btw, I'm CC'ing the backports mailing list, which is a better place to
ask these sorts of questions)
I found that the backports cross-compile process worked much the same
way as building compat-wireless. This is what I'm doing currently in my
build script: (This is using a backports package generated last night
using the backports git HEAD code with the cw1200 driver integrated)
set -a
CROSS_COMPILE=${CROSS_COMPILE}
ARCH=${TARGET_CPU}
KLIB_BUILD=${DEV_PATH}/${LINUX_DIR}
KLIB=${TARGET_ROOT_ON_HOST}
set +a
make oldconfig # menuconfig worked here too
make
make install
That said, the 'make install' target isn't currently sane for
cross-builds due to the bacport_firmware_install script not respecting
prefixes. I just commented that script (and a few others like initrd
updates) out of the Makefiles, and I had a successful build/install.
