Hello,
Following the question asked by Will yesterday, I just went ahead and
implement a small tool that generates a graph of dependencies for a
given package.
The result of this tool for the libgtk2 package can be seen at
http://free-electrons.com/~thomas/libgtk2-package-dependencies.pdf
This is the kind of funny things we can do with a generic package
infrastructure :-)
The implementation of this tool is available in my graph-dependencies
branch at
http://git.buildroot.net/~tpetazzoni/git/buildroot/log/?h=graph-dependencies.
There are three commits in this branch:
* package: Add new <pkg>-show-depends to list dependencies
http://git.buildroot.net/~tpetazzoni/git/buildroot/commit/?h=graph-dependencies&id=27ad37038055e5af12546a5941099264f37feecc
* package: optimize the implementation of UPPERCASE
http://git.buildroot.net/~tpetazzoni/git/buildroot/commit/?h=graph-dependencies&id=b6a46aaed9e497503b66789d1b212473d7c78b58
* New graph-depends script
http://git.buildroot.net/~tpetazzoni/git/buildroot/commit/?h=graph-dependencies&id=99c53bd52389c003707335d454d1bd1cace9ebfb
Regards,
Thomas

My eyes! ;)
We could instead do something like gmsl does (http://gmsl.sf.net):
az := a b c d e f g h i j k l m n o p q r s t u v w x y z . -
AZ := A B C D E F G H I J K L M N O P Q R S T U V W X Y Z _ _
UPPERCASE = $(eval __tmp := $1) \
$(foreach c, $(join $(addsuffix :,$(az)),$(AZ)), \
$(eval __tmp := \
$(subst $(word 1,$(subst :, ,$c)),$(word 2,$(subst :, ,$c)),\
$(__tmp)))) \
$(__tmp)
It loops through a character list of the form a:A b:B .., and
substitutes the 1st charact for the second.
This is written as a generic tr function, we could ofcourse merge az and
A-Z if we only ever want to do uppercase.

I've slightly improved this script, and it is now capable of generating
the dependency graph for a full Buildroot configuration, i.e taking
into account all packages that have been selected.
See http://free-electrons.com/~thomas/buildroot-full-dependencies.pdf
for a fairly large example involving X.org and Gtk.
As always, the code is available in
http://git.buildroot.net/~tpetazzoni/git/buildroot/log/?h=graph-dependencies.
Besides the modifications in the script itself, the modifications in
the rest of Buildroot are very small.

Great! Care to write a bit of documentation about it, then I'll pull it?
