Or specify the target object you want to make, so for a source file... make ARCH=arm CROSS_COMPILE=arm-eabi- drivers/hwmon/lsm303dlh_m.o or for a loadable module make ARCH=arm CROSS_COMPILE=arm-eabi- drivers/foo/bar.ko Though, once you've done a failed make once, and corrected the source code, I would have thought then next make would take next to no time for the objects it had already built and so wouldn't be worth doing these shortcuts. (Perhaps I just lucky to have a fast machine with a decent amount of RAM.) -- Tixy _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
