 |
|
It seems that http://www.gentoo.org/proj/en/base/sparc/multilib.xml doesn't work anymore. I tried to access the binhost, but it doesn't exist.
So, I can not compile either multilib gcc or glibc. Any workarounds for this? |

Simba7,
I have multilib SPARC on a dead U10 that I replaced with a Raspberry Pi.
I may be able to recover a few packages from the HDD. As it was ~SPARC, I used to run it with FEATURES=buildpkg.
What packages do you want?
64 bit userland on SPARC is generally a bad thing as you loose half the CPU registers.

I think just gcc and glibc.

So, 64bit on SPARC is a bad thing? Should I stick with just 32bit userland? |

I think you're misinterpreting something here.
The SPARC's floating-point registers are organized such that an even-odd pair of single-precision (i.e., 32-bit) registers act as a single double-precision (i.e., 64-bit) register.
This has nothing to do with integer registers, and has nothing to do with 32-bit vs 64-bit ABIs.

mattst88,
Thank you for clearing that up.
Wasn't it you that did mulilib SPARC in the first place?

Ahh. Ok. I still want to go multilib on these systems.
If you need a maintainer, I'd be willing to volunteer. |

Simba7,
The binaries for multilib SPARC that I have (gcc and glibc) are at http://grytpype-thynne.org/~roy/Simba7/
OK I have another glibc but you won't want that. It rendered my box unbootable :)
Have fun.
Contact the proxy maintainers project if you wish to help out, or post bugs with patches at bugs.gentoo.org
