Subject: [PATCH 0/6] Evolve SDK to chroot-free usage
Date: Sun, 22 Mar 2020 09:37:15 +0100	[thread overview]
Message-ID: <cover.1584866240.git.jan.kiszka@siemens.com> (raw)

Currently, our SDK can primarily be used by chroot'ing into it, taking
the to-be-built project with you (bind mount etc.). This was enough for
a start but we can do better.

This series enhance the SDK to become usage as a normal cross-toolchain
on your host system. For that purpose, we add a script that relocates
the toolchain after installation, adjust binary search paths and
sysroot. So, the only remaining difference to a yocto or buildroot
toolchain is the need to run the relocation script once after unpacking
the SDK.

The series furthermore allows to customize the SDK content via the
image-generating layer.

The series (together with all other pending patching of mine) can also
be found at https://github.com/siemens/isar/commits/jan/queue.

While I already shrunk the SDK a bit by removing the now obsolete
isar-apt repo, I suspect we could further reduce the deployment size by
dropping chroot support completely, only including the compiler and
their library dependencies. OTOH, sdk-debian-buster-arm64.tar.xz is now
142M here, unpacked 680M, while ARM's
gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz has
260M packed and 1.5G(!) unpacked. So we are either not really off or are
still missing something.
