progress update: |
2 |
- binutils-2.22 in ~arch should work fine |
3 |
- glibc-2.14.1-r1 in ~arch includes support when "x32" is in MULTILIB_ABIS |
4 |
- linux-headers-3.1 includes support when "x32" is in MULTILIB_ABIS |
5 |
- you'll still need gcc-4.7 from the toolchain overlay |
6 |
- a 3.1 kernel can be obtained here: https://github.com/hjl-tools/linux |

8 |
the only problem is with bootstrapping. there is no way atm to live migrate |
9 |
between multilibs on your system. this isn't a new problem ... we've been |
10 |
punting all bugs where people try to go from MULTILIB_ABIS="amd64" to "x86 |
11 |
amd64" on a live system. same issue applies when adding "x32" to the list. |

|
13 |
i've been contemplating how to address this, but so far, it seems like the |
14 |
easiest is to post a glibc binpkg which includes all possible ABIs and have |
15 |
people install that first. then they should be able to install gcc/linux- |
16 |
headers freely and rebuild glibc after that. |
