[Q] Building KK AOSP from Sony Sources topic

Hi,

As some of you might be aware of, Sony released the sources to enable building of AOSP straight from their sources for the Z2 (and other devices also).

I was just wondering if any of you has been able to build from those sources ?

I can init the repo.
I can sync the repo.
I can build the envsetup.
But then when it comes to compile the whole bunch, I always end up with an error message stating the I use a version of Make that is too young (4.1) and that I should use 3.8 instead...

Any clue on how to solve this ?
I guess it's trivial, but I have no idea how to proceed :(

Regards.
