Compiling

GRUB

• Getting Started / Build Instructions / To build grub individually _(LBV2)

Kernel

Application

Static busybox

The following steps demonstrate how to build the static busybox.

• Install cross tool chain

1. To build all image files
2. To build toolchain installer
3. Setting up SDK
4. Setting up cross compiling environment

• Install static linked libraries for cross compiling

(Because the static linked libraries contained in cross toolchain installer are not full enough as contained in the yocto building environment.)

$ pushd ${BSP_HOME}/${BDIR}/tmp/sysroots/quark && tar zcvf ~/static_lib.tgz `find ./ -name "*.a"` && popd

(Copy ~/static_lib.tgz from docker container to home directory in local file system if needed)

$ sudo tar xvf ~/static_lib.tgz -C /opt/iot-devkit/${POKY}/sysroots/i586-poky-linux --no-same-owner

• Unpack busybox tarball

$ mkdir -p ~/code/test_quark

$ tar xvf busybox-1.22.1.tar.bz2 -C ~/code/test_quark

$ cd ~/code/test_quark/busybox-1.22.1

• Select the option, "Busybox Settings ---> Build Options---> [*] Build BusyBox as a static binary (no shared libs)"

$ make menuconfig

Exit and Save

• do compiling

$ make

Eventually, the two files, busybox and busybox_unstripped, are built and located in directory "~/code/test_quark/busybox-1.22.1".

SDcard image

To build from prebuilt image, please refer to the following sections for details.
