Then go to the busybox directory: cd /develop/sysapps/busybox-1.00 .

You can configure the make options using a graphical interface by entering:

make menuconfig

You can select individual commands and features here.

Enter the path to the cross-compiler under „Build options1“ (normally /usr/bin ). You also

need to enter the path to the root file system ( /develop/rootfs in this example) under

„Installation options“.

Finish by compiling and installing:

make dep

make

make install

The functionality of the TinyLogin package has been integrated into newer versions of

Busybox. If you select these functions (e.g., passwd etc.) in the configuration, the compiled

Busybox binary must have setuid root permissions in order for these applets to work

correctly.

chmod 4755 /develop/rootfs/bin/busybox

As an alternative, you can install TinyLogin separately and leave out the section

7.3. Installing the MTD-utilities

The MTD (memory technology devices) utilities are required for partitioning, copying and

erasing the flash memory.

To be able to install the MTD utilities on the target system, you need the compression

library zlib.

Copy zlib from the software CD and unpack it:

cp /dev/cdrom/build-tools.tgz /tmp (where /dev/cdrom is the starterkit-CD)

tar -xzvf build-tools.tar

mv /tmp/build-tools /develop

Then go to the directory and set it up to compile:

cd /develop/build-tools/zlib-1.2.1/

CC=arm-linux-3.4.2-gcc LDSHARED=“arm-linux-3.4.2-gcc -shared“

./configure –shared

The variable CC sets the cross-compiler and zlib is compiled as a dynamic library by

setting LDSHARED.

Next, compile zlib and install it in the directory indicated by prefix:

make

make prefix=/usr/arm-linux/lib install

After the library has been installed, you can copy it to the target system:

cd /usr/arm-linux/lib

cp -d libz.so* /develop/rootfs/lib

Now you can install the MTD utilities (skip these steps if you have already installed the

busybox before):

cp /dev/cdrom/sysapps.tgz /tmp

tar -xzvf sysapps.tar
