I try to compile softwares with a 32 bits libc, old enough to be compatible with my customers.

So I have installed Debian Squeeze (6) 64 bits this last days (so after deprecation date) in a ProXmox container.

I have set the archive repositories to allow me to update / install packages, it works. My sources.list is:

deb http://archive.debian.org/debian squeeze main contrib non-free
deb http://archive.debian.org/debian squeeze-lts main contrib non-free
# Backports
deb http://archive.debian.org/debian-archive/debian-backports squeeze-backports main contrib non-free
# Security
deb http://archive.debian.org/debian-security squeeze/updates main contrib non-free

I have to say, there was a lot of outdated GPG Keys, and after update, a few are always outdated, they seem to be unsupported anymore.

My current version of dpkg is 1.15.11 the original Squeeze versio where the multiarch functionnality is not present. It apears only in 1.16... Good enough, the backports listed upper contain wheezy packages where dpkg is in version 1.16.9 .

http://archive.debian.org/debian-archive/debian-backports/pool/main/d/dpkg/

But I am not able to install this backports. When I run the command

apt-get install -t squeeze-backports dpkg

It responds:

Reading package lists... Done
Building dependency tree
Reading state information... Done
dpkg is already the newest version.
 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

apt-get policy dpkg returns

dpkg:
  Installed: 1.15.11
  Candidate: 1.15.11
  Version table:
 *** 1.15.11 0
        500 http://archive.debian.org/debian/ squeeze/main amd64 Packages
        100 /var/lib/dpkg/status

If I ask, it's because I am pretty sure to have set things right. I guess I am on the frontier where archived versions have there limits.

  • Could you edit your question to show the output of apt-cache policy dpkg? – Stephen Kitt Jun 1 '18 at 7:33
  • Also, since you’re installing a VM seemingly for the sole purpose of building software with an old 32-bit C library, why not install 32-bit Debian 6 directly? Then you wouldn’t have to involve cross-architecture builds. – Stephen Kitt Jun 1 '18 at 7:40
  • @Stephen sure... but I don't really know what this info means. I haven't found a prepared container base in 32 bits... and I have other compilation environements where the 64bits are not a problem, I assumed it would be the same with this dist. – Sandburg Jun 1 '18 at 7:44
  • Did you run apt-get update after adding backports to sources.list? – Stephen Kitt Jun 1 '18 at 7:46
  • You might not actually need multi-arch at all; try installing gcc-multilib and building with gcc -m32. – Stephen Kitt Jun 1 '18 at 7:47

For a 32-bit (i386) build on a 64-bit (amd64) on Debian 6, you shouldn’t need multi-arch; if you install gcc-multilib or g++-multilib (depending on your goal) and compile with gcc -m32 (or g++ -m32) you should get the result you’re after.
