01:16 <shlevy> Any github org owners around?

01:16 <shlevy> domenkozar niksnut garbas ikwildrpepper ?

01:18 <shlevy> Never mind, turns out what I want just isn't possible :(

01:57 <shlevy> dtz: around?

02:59 <lopsided98> I figured out the problem with the kernel cross compilation

03:00 <lopsided98> The 'overrideCC' in the kernel derivation is using host gcc7, so it tries to cross-compile gcc (not build a cross compiler), which doesn't work (and is also incrrect behavior)

03:03 <shlevy> Ouch :(

03:03 <shlevy> lopsided98: Does it work if you switch it to targetPackages.gcc7? Is that the right one to use even? :D

03:04 <shlevy> Or maybe it's buildPackages.gcc7... Not actually sure

03:04 <lopsided98> buildPackages.gcc7 fixes it

03:04 <shlevy> OK, can you open a PR for that?

03:04 <shlevy> Or just push if you have commit bit

03:05 <shlevy> I'd like to ping Sonarpulse to see if that's the right way to do it

12:56 <hl> Aaah! So that's what's going on.

12:56 <hl> I was wondering why trying to cross-compile Linux for aarch64 was causing it to try and build a native gcc for aarch64.

12:57 <vcunat> you mean this https://github.com/NixOS/nixpkgs/pull/35091 ?

12:58 <hl> Yeah. So basically https://github.com/NixOS/nixpkgs/issues/35106

12:58 <hl> Fairly sure that's still an actual problem if you want to cross-compile a non-cross gcc for AArch64, but the fact that trying to compile Linux was trying to compile a non-cross AArch64 gcc in the first place made no sense.

13:14 <hl> Nice, with that fix Linux seems to be successfully cross-compiling for AArch64.l

19:57 <dtz> awesome! all our compilers are a bit "confused" in a cross setting, would be interested in any efforts towards fixing this

20:02 <dtz> all the compilers not built as part of the cross stdenv, I mean

20:41 <shlevy> Can I get permission to upload stuff to tarballs.nixos.org?

20:41 <shlevy> Building a native riscv64 stdenv bootstrab

20:42 <clever> shlevy: one min

20:43 <clever> shlevy: https://github.com/NixOS/nixpkgs/blob/master/maintainers/scripts/copy-tarballs.pl

20:43 <clever> shlevy: this script goes over every .src in nixpkgs, for those with acceptable licenses,and builds the list for tarballs.nixos.org

20:43 <clever> shlevy: so if you meet the right rules, and your PR gets merged, i think it will just happen automatically

20:44 <clever> the source should show what the rules are, and running the related nix files should confirm

20:45 <shlevy> clever: I need to upload one for the bootstrap tarballs

20:45 <shlevy> It's a different directory, and not a fetch

20:45 <clever> shlevy: ah, i dont know how those are handled

21:09 <vcunat> I'm just curious, do you have actual real CPU with risc-v?

21:15 <shlevy> Coming in April

21:21 <vcunat> So you're getting ready in advance :-)

21:22 <shlevy> Yeah :)

21:35 <dtz> wait so can I stop hosting the musl bootstrap bits? O:)

21:35 <dtz> similarly, I think the aarch64 tarballs are hosted elsewhere

21:36 <shlevy> Yep

21:36 <shlevy> It's annoying :/

21:36 <dtz> don't really mind but it'd probably be best to have them more reliably hosted

21:53 <LnL> can't somebody put them on tarballs.nixos.org

21:54 <shlevy> That's exactly what we're discussing :)

21:54 <LnL> I know copumpkin does that for the darwin stuff

22:18 <dtz> riscv stuff on master?? ^_^

22:18 <dtz> and glibc 2.27

22:18 <dtz> is this real life

22:20 <shlevy> dtz: glibc 2.27 is on a branch still :D

22:22 <dtz> oh, just saw 2.27.nix and some fixes on master

22:23 <dtz> not default yet, I see :)

22:23 <shlevy> Yeah
