Get newest gcc for debian?

Question

I can't build my apps on gcc since I use various c++0x features. I'm on Debian 6 (Lenny) and after upgrade/updating I have gcc version 4.4.5-8. I'm unsure which version is required but mingw 4.6.2 works. gcc 4.7.0 is out.

How do I install gcc version 4.6+ on Debian?

Solution 1

Debian 6.0 is Squeeze (currently stable); Lenny was 5.0 (currently oldstable). I'll assume you meant Squeeze.

Use apt-pinning to safely add Wheezy (currently testing) to your sources.list, then install gcc-4.7/wheezy.

In other words, your /etc/apt/sources.list should look something like this:

deb local.debian.mirror squeeze main
deb local.debian.mirror wheezy main

while your /etc/apt/preferences should look something like this:

Package: *
Pin: release n=squeeze
Pin-Priority: 900

Package: *
Pin: release n=wheezy
Pin-Priority: 200

(The exact numbers don't matter too much; see man 5 apt_preferences for details on what various ranges mean.)

This will prevent testing packages from being unintentionally installed. (Of course, you could just upgrade your whole system to testing.)

You may get some resolution errors with apt-get install gcc-4.7/testing as it will have dependencies that require versions greater than stable; apt-get --target-release testing install gcc-4.7 will set testing to priority 990 for the duration of the command.

Solution 2

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.

[Admin]

Are you looking for an alternative to downloading the gcc source files and compiling yourself, or are you ok with building the package from source?

[Admin]

@sbtkd85 whichever gets the job done but i prefer the simplest way like downloading binaries or adding a repo to apt-get or such

[Admin]

Lenny is Debian 5. Squeeze is Debian 6. Are you on 5 or 6?

[Admin]

Also, is there a particular reason you need 4.7? One of the reasons Debian doesn't rapidly add the latest versions is because they feel production level stability trumps having the latest and greatest.

@acidzombie24: If you mean squeeze, as I think you do, please edit your question to say that. Thanks.

This is an incorrect and possibly dangerous procedure. Mixing binary packages from two different versions of Debian is a Bad Idea. The correct approach is backports. See unix.stackexchange.com/q/112157/4671

@maitu Did it work for you? I'm desperate enough to try anything at this point. Anyone I don't think gcc is in a backport release (I need 4.7)
