Building DDKs  2006, QNX Software Systems GmbH & Co. KG.

You must run:

. ./setenv.sh

before running make,ormake install.

Additionally, on Windows hosts you’ll need to run the

Bash shell

(

bash.exe) before you run the . ./setenv.sh command.

If you fail to run the

. ./setenv.sh shell script prior to building

the DDK, you can overwrite existing binaries or libs that are installed

$QNX TARGET.

Each time you start a new shell, run the

. ./setenv.sh command.

The shell needs to be initialized before you can compile the archive.

☞

The script will be located in the same directory where you

unzipped the archive ﬁle. It must be run in such a way that it

modiﬁes the current shell’s environment, not a sub-shell

environment.

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.
