[elbe-devel] Best way to build kernel & u-boot in an elbe setup?

[Norbert Nemec | BLOKS.]

Hi there,

I am just trying to set up our build environment with elbe.

As a starting point, I had a buildroot environment that cross-compiled 
custom builds of the kernel and u-boot and set up every perfectly to 
boot correctly. Doing this cross-compiling is part of the buildroot 
configuration, so I had a straightforward, complete solution to build 
the whole system, described by a small set of configuration files.

So far, with elbe, I just re-used the binaries from the buildroot setup. 
But I would like a straightforward, reproduceable and documented way to 
build my system. I am therefore setting up scripts that do the necessary 
steps with elbe. However, I am not quite sure how kernel and u-boot 
should best be built.

Currently, I am cross-compiling kernel and u-boot inside the initvm. 
Compiling them inside the virtual target architecture seems like a waste 
of time, since cross-compiling is really straightforward for these pages.

I understand the value of the virtual environment to avoid 
cross-compiling of applications with all their library dependencies. For 
kernel and boot-loaded I don't see the point.

Is this really the way to go? How do others build kernel&bootloader with 
elbe? How is it supposed to be done?

Greetings,
Norbert
