| |
Basically it only enables that was added by previous couple fixes. Sysroot contains correct libs installed and its headers. Useful when working with NFC or virtual machine.
Usage example:
clean (on demand) make ARCH=arm -C samples/bpf clean make ARCH=arm -C tools clean make ARCH=arm clean
configure and install headers:
make ARCH=arm defconfig make ARCH=arm headers_install
build samples/bpf: make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- samples/bpf/ \ SYSROOT="path/to/sysroot"
