This series is a snapshot of my attempt at using crosstool-NG as a backend
to generate the toolchain.
The series is two-fold:
- patch 1..5 are cleanups to lay down a proper base to add a new backend
- patch 6 is the actual addition of crosstool-NG as a new backend
This series is not final! It is *not* intended to be included as is.
It is posted for preliminary review, so as to make it ready for early
inclusion in the next release cycle.
Of particular interest:
- patch 1..4 appear to be complete, but have been lightly tested, as my
primary goal is to first add crosstool-NG as a backend, and then fix the
broken stuff in a generic way.
- patch 5:
I have not thoroughly checked that the renaming was complete. There might
be some packages that still depend on the old target, especially gdb,
which has a dependency on 'uClibc', and I haven't checked that one (yet).
- patch 6:
The toolchain is only built, not installed, and a lot of options from BR
are not yet pushed into crosstool-NG's .config.

The helper functions used for external toolchains may also be useful
to alternate toolchain backends (currently, only external toolchain
is the sole user).

To: buildroot
From: Yann E. MORIN <yann.morin.1998@anciens.enib.fr>
Rename the external toolchain directory.
When new backends are here, it will be easier to sort them out
if they are all prefixed the same way.

-# BR2_INET_RPC) are needed at configuration time because these
-# options are used as dependencies for other options. And at
-# configuration time, we are not able to retrieve the external
-# toolchain configuration.

Including a bunch of Makefiles with wildcard makes it impossible
to add new toolchain backends. Avoid that by namely including
needed files.

It is misleeading to name the external toolchain make target 'uclibc', as
external toochains can be based on other C libraries (eg. glibc or eglibc).

Hello Yann,
I did a quick review of your patches, and found nothing specific to
say, it looks good to me.
I would at least like patches 1 -> 5 to be merged early in the release
cycle of 2010.08, because I have other changes to make on external
toolchain support that will depend on these. So don't wait for the
CT-NG support to be fully ready to send preliminary patches cleaning up
things that you need for CT-NG integration.
Thanks!
Thomas

Hello Yann,
I'd like to make some changes in the configuration options related to
toolchains. As I don't want to break your work on Crosstool-NG, could
you please send an official pull request for patches 1 to 5 to the
list, so that Peter can merge this early cleanup/preparation work, and
I can base my changes on top of it ?
Thanks!
Thomas
