I just tested this in an out-of-tree situation... and it doesn't work.
It generates the dependency graph of the configuration that is in the
Buildroot source tree (I happened to have one) and not the one of the
Buildroot build tree.
To reproduce:
cd buildroot-sources/
make menuconfig
# create some configuration 1
mkdir ../buildroot-build
cd ../buildroot-build
make -C ../buildroot-sources O=$(pwd) menuconfig
# create some configuration 2
make graph-depends
The generated graph will correspond to "configuration 1" and not the
expected "configuration 2".
I suspect it's a problem in the graph-depends script itself rather than
the integration you made, but I haven't looked in detail.
Cheers,
Thomas
