Backporting to squeeze/stable is possible, but non-trivial. Here is a patch against files in the debian
directory that applies against the 4.7.0-1
Debian sources in testing (should also work against the presumably slightly different version 4.7.0-3
in unstable), and should allow one to successfully build on squeeze, though I have not tested the patch directly by applying it to pristine sources. Obviously, installing binary packages from testing on stable is possible, but not a good idea in general. Doing such things is a recipe for instability, and defeats the purpose of using stable in the first place. However, backporting in this fashion should not force any additional upgrades, and cause no problems with your system.
I don't recall making changes to rules.parameters
, but most of the rest of the patch is changes I made, as opposed to machine generated changes. Try applying this patch to the Debian sources, and running debuild binary
or similar. I could upload the patch somewhere if there is interest, and if getting it from this message is not convenient. Reports of success and failure welcomed.
Notes:
- This will require installing a bunch of build dependencies, but only from squeeze,
and apt-get build-dep
won't work since the build dependencies have been locally
altered - you'll have to do it manually.
- The build of
libgcc1-dbg
was giving errors, so I took it out.
- The test suite has some problems, so I disabled them. See the lines
with_check
:= disabled by hand
. The issue is not the tests failing, but the
build can't find some files related to the tests, so it errors out.
- I replaced
binutils
by the version in squeeze, namely binutils (>=
2.20.1)
.
- I disabled
multilib
, since squeeze does not use it.
- This version was tested on amd64, but should also work in i386 at least.
