'make' tips
-----------
This is a collection of tips that help you make the most of OpenADK.
.Configuration searches:
The +make menuconfig+ command offer a search tool.
The search tool is called by pressing +/+;
The result of the search shows the help message of the matching items.
.Display all commands executed by make:
--------------------
$ make v
--------------------
or
--------------------
$ make VERBOSE=1 <target>
--------------------
.Display all available targets:
--------------------
$ make help
--------------------
.Cleaning:
There are different cleaning targets available. If a full clean is
necessary, you normally will get a message from OpenADK.
To delete all build products (including build directories, target, host
and pkg trees, the firmware and the toolchain for all targets):
--------------------
$ make cleandir
--------------------
If you even want to clean any downloaded source and your
confiuration +.config+:
--------------------
$ make distclean
--------------------
If you only want to clean the kernel build, because you added or
removed some patch, just do:
--------------------
$ make cleankernel
--------------------
This is automatically triggered if you change the kernel version in
your configuration.
If you just want to clean all packages and wants to rebuild the firmware,
(the tools/toolchain is not deleted) just use:
--------------------
$ make clean
--------------------
.Resetting OpenADK for a new target:
You can either delete the configuration and start from scratch:
--------------------
$ rm .config*
$ make menuconfig
--------------------
Or you can save your existing configuration and switch to a new
one with:
--------------------
$ make switch
--------------------
Afterwards you can switch back to your old configuration, you just
need to remember, which architecture and system you had configured:
--------------------
$ make switch ARCH=<arch> SYSTEM=<system>
--------------------
OpenADK is designed to have multiple architectures and embedded system
combinations configured and build without a need to rebuild everything
from scratch. There is no limit, you just need to have enough disk space.
