the components may take a while, it is often useful to perform this step by itself after configuration.

The get makefile target can be used to perform this step.

Note that the original web locations are generally used for each library supported by the userland build. This is generally a good thing, but also means that things sometimes move.

We try to keep a set of archives on the Boundary Devices website for use when the original sources are unavailable.

Look here if you can’t find something.

3.Build libraries under build/ the system through the kconf tool. As mentioned earlier, the build tool allows you to express inter-library dependencies in their makefile packets.

The packets for each component are stored in userland/rules and consist of both a configuration piece *.in and build instructions *.make.

The install target can be used to simply build the components with- out making a root filesystem.

4.Install libraries into install/. This mingling of various libraries is done to allow simplified include file and library references for depen- dent packets.

5.Build a root filesystem under root/. This step gathers all of the executable portions (applications and shared libraries) for each component into a root filesystem image. Scripts are also commonly installed, as are any supporting configuration files (under root/etc).

The rootfs target can be used to create the root filesystem without creating a flattened image.

6.Build a device table. This step uses the kernel configuration file to create devices.txt, suitable for use with genext2fs, mkcramfs, or mkfs.jffs2.

The devices target can be used to create the device table without performing any other build steps.

7.Flatten the root filesystem into any of cramfs, initrd, or JFFS2 images for placement in flash or SD card.
