@winter:catgirl.cloudWinter tried doing the cursed thing of:
  1. build old glibc in stage2

  2. build new xgcc in a subsequent stage, using the old xgcc's stdenv, but pointing to the old glibc as build sysroot

  3. use that xgcc like nothing has changed

but that also blows up, i guess expectedly

@winter:catgirl.cloudWinteri guess there is really no nice way forward here lol19:47:30
@winter:catgirl.cloudWinter(i really don't wanna use an old nixpkgs!)19:47:37
@winter:catgirl.cloudWintercuriously, it also seems like my xgcc in between stages 2/3 and the binutils in stage4 can build at the same time?!19:52:01
@winter:catgirl.cloudWinteri have no clue how on earth that's possible19:52:46
@pyrox:pyrox.devdish [Fox/It/She]ugh why is our bootstrap not following the live-bootstrap build chain19:54:43
@winter:catgirl.cloudWinter🤔19:55:08

@pyrox:pyrox.devdish [Fox/It/She] talking about minimal-bootstrap which is fully from source and should be(but clearly isn't) following the build chain that live-bootstrap establishes 19:56:12
@pyrox:pyrox.devdish [Fox/It/She]sorry if that was confusing19:56:26
@pyrox:pyrox.devdish [Fox/It/She]* sorry if that was confusing and/or not what you were talking about19:56:32
@winter:catgirl.cloudWinterit's not19:56:48
@winter:catgirl.cloudWinteri am talking about our normal bootstrapping process19:57:05
@winter:catgirl.cloudWinterperhaps minimal, if it actually works (last i heard it doesn't?), would be nicer for my crimes19:57:27
@pyrox:pyrox.devdish [Fox/It/She]it doesn't19:57:42
@pyrox:pyrox.devdish [Fox/It/She]im trying to fix and update it19:57:47
@pyrox:pyrox.devdish [Fox/It/She]* it doesn't afaik19:57:51
@pyrox:pyrox.devdish [Fox/It/She]so we can start the transition to using minimal-bootstrap as our regular bootstrap19:58:06
@emilazy:matrix.orgemily our thing isn't live-bootstrap 20:14:50
@emilazy:matrix.orgemily live-bootstrap is a newer thing that goes via a billion OSes etc. 20:14:58
@emilazy:matrix.orgemilyour thing is the older Linux-only thing, I think based on the Guix chain20:15:09
@winter:catgirl.cloudWinteryep ^^20:16:31
@winter:catgirl.cloudWinterwhy is glibc so intertwined with binutils ughhh20:17:15
@winter:catgirl.cloudWinterthis would be so much easier if i just didn't have to bootstrap just to change the glibc version even if i'm fine depending on a different (later) glibx20:17:46
@winter:catgirl.cloudWinter* this would be so much easier if i just didn't have to bootstrap just to change the glibc version even if i'm fine depending on a different (later) glibc20:17:50
@winter:catgirl.cloudWinteri wonder how other distributions that ship {new gcc, old glibc} do it20:19:35
@qyliss:fairydust.spaceAlyssa RossWhy are you doing thi20:19:43
@qyliss:fairydust.spaceAlyssa Ross * 20:19:47
@winter:catgirl.cloudWintera stupid hack to build glibc-based binaries/libs that are compatible down to e.g. ubuntu 18.0420:20:33
@qyliss:fairydust.spaceAlyssa RossDo you patchelf them at the end then?20:20:58
