In ksh and bash shells, All shell scripts are executed in a sub-shell by default.

Therefore, it’s important that you use the syntax

. <script>

which will prevent a sub-shell from being used.

Each DDK is rooted in whatever directory you copy it to. If you type

make within

this directory, you’ll generate all of the buildable entities within that DDK no

matter where you move the directory.

all binaries are placed in a scratch area within the DDK directory that mimics the

layout of a target system.

When you build a DDK, everything it needs, aside from standard system headers, is

pulled in from within its own directory. Nothing that’s built is installed outside of

the DDK’s directory. The makeﬁles shipped with the DDKs copy the contents of

the

prebuilt directory into the install directory. The binaries are built from

the source using include ﬁles and link libraries in the

install directory.
