Hi,

This week I worked on packaging crosstool-ng 1.23 for Debian using 
existing work.

I found that some dependencies are missing from the binary package so 
`ct-ng build` works correctly with minimal base system (like m4, wget).

I also added patches:
- 0001-Disable-MAKELEVEL-check.patch:
    An alternative to setting MAKELEVEL=0 inside debian/rules.
    This patch comments out the check of MAKELEVEL inside `Makefile.in`.

- 0002-Makefile.in-remove-recursive-part.patch:
    This patch fix the infinite recursion issue. I should probably share 
this into crosstool-ng and put the following text into the patch 
description :).
    The issue is that Debian dh run `make -n` which give `nrR` inside 
MAKEFLAGS and the `filter` function only matches whole words.
    Using `findstring` replaces every occurrences of the given text, 
making the assumption that no long options will contain `rR` or `Rr`.

- 0003-Backport-commit-Fix-debuild-warnings-errors.patch:
    This patch backports the commit [1] to fix lintian warning and errors.

I added installation of the bash completion script into 
/usr/share/bash-completion/completions (which is the new directory 
replacing /etc/bash_completion.d/).

I've added a watch file which use [4] and checks the gpg signature 
against `debian/upstream/signing-key.asc`.
The signing-key.asc file contains public keys of Alexey Neyman and Bryan 
Hundven (not sure if they are all the needed signatures).

I added a autopkgtest test to build a `arm-unknown-eabi` toolchain to 
check that the built package is working properly.

I put my package sources on github [2] with a travis configuration to:
- Build on travis a schroot of unstable (as travis use old ubuntu releases)
- Use this schroot to run sbuild inside which also run lintian and 
autopkgtest.
- Not that relevant but travis-ci also upload the built package to 
bintray when building a tag.

I use git-buildpackage to manage the source package.
My workflow is documented at `debian/README.source`.

Due to the length of the toolchain building and limitation of travis 
build max duration, I only test one toolchain build (arm-unknown-eabi).
FYI, Travis sbuild logs are available here [3].

I'm not sure about my medium/long term availability to maintain this 
package, but I hope what I have done can help to get crosstool-ng into 
Debian :)

Thanks for doing so.


> using existing work.

Most likely you missed some of the existing work.
We, Chris, you (Alexis Murzeau) and I (Geert),
need to find out what work exists and merge it in one.

What is needed that some of us says:
  URL is for the time being the leading SCM repository

 git repro https://github.com/cpackham/crosstool-ng.git  
 branch debian-packaging-update

Yes, some indepency from upstream has advantages

The changes from that branch have been merged to the upstream repo so 
it's effectively dead. I'll probably delete it shortly.

Sorry hit send too soon :(.

Separating them is probably a good idea short term at least. I'd like to 
get the current released version 1.23 packaged. This may require patches 
to fix lintian issues (some of which have already been applied to master).

Longer term we can decide to either maintain the packaging completely 
separately (and remove the /debian directory from crosstool-ng.git) or 
bribe Alexy to make it part of the upstream release process.
