@jcie74:matrix.orgpie_idk te enterprise gpu stuff, k20s and k40s or soemthing, also something about xeon phi02:30:06
@tpw_rules:matrix.orgtpw_rulesi intend to write up and publish how i did that at some indefinite point...02:30:07
@tpw_rules:matrix.orgtpw_rulesooh02:30:17
@jcie74:matrix.orgpie_ * idk the enterprise gpu stuff, k20s and k40s or soemthing, also something about xeon phi02:30:20
@tpw_rules:matrix.orgtpw_rulesxeon phi is firmly in the nerd kitsch category at this point i'm pretty sure02:30:36
@jcie74:matrix.orgpie_but yeah its ~10 year old hardware02:31:20
@jcie74:matrix.orgpie_anyway02:31:23
@jcie74:matrix.orgpie_I am trying to rebuild the world, at least as far as im needing it, on musl02:31:38
@jcie74:matrix.orgpie_tats most of the pain so far02:31:43
@jcie74:matrix.orgpie_i mean nix is at least making it feasible02:31:47
@tpw_rules:matrix.orgtpw_ruleswhy02:31:47
@tpw_rules:matrix.orgtpw_rulesthat's the real danger of nix02:31:56
@jcie74:matrix.orgpie_because i need a libc that works with an old kernel?02:32:09
@tpw_rules:matrix.orgtpw_rulesoh yes that makes sense02:32:20
@jcie74:matrix.orgpie_apparently musl supports everything more or less02:32:39
@jcie74:matrix.orgpie_gcc broke compatibility at some point02:32:47
@jcie74:matrix.orgpie_ * glibc broke compatibility at some point02:32:56
@jcie74:matrix.orgpie_musly explicitly supoprts 2.6.36 or 2.6.39 i think02:33:17
@jcie74:matrix.orgpie_ * musl explicitly supoprts 2.6.36 or 2.6.39 i think02:33:25
@jcie74:matrix.orgpie_and ajs pointed out to me that we have a special glibc courtesy of vcunat IIRC that would work with rhel6 but I dont think I have a highe nough patch level02:34:02
@jcie74:matrix.orgpie_ * and ajs pointed out to me that we have a special glibc courtesy of vcunat IIRC that would work with rhel6 but I dont think I have a high enough patch level02:34:12
@jcie74:matrix.orgpie_ the more you know shrug 02:34:19
@jcie74:matrix.orgpie_though my guess is rhel is patchd to suppot the libc then and not so much the other way around, idk02:35:08
@jcie74:matrix.orgpie_

currently im

  • mutilating fhsuserenv trying to get it to eval withmusl
  • trying to get some python stuff to build
02:35:55
@jcie74:matrix.orgpie_appppaaaarrently fhsuserenv only works with glibc? Im not sure02:36:12
@jcie74:matrix.orgpie_I tried to remove all the i686 stuff but something is still hanging on and preventing me from evaling02:36:30
@jcie74:matrix.orgpie_(i think I just waited for 3 fortran stage compiles on the side or something...blas and lapack are compiling..)02:37:15
@jcie74:matrix.orgpie_
In reply to @tpw_rules:matrix.org
that's the real danger of nix
Im wondering if this is a more feasible way of upgrading userspace if, and until, we can upgrade the kernel
02:37:58
@jcie74:matrix.orgpie_its an open question why its so old, we are supposed to get custory of the machine...at some point02:38:38
@jcie74:matrix.orgpie_ * its an open question why its so old, we are supposed to get custody of the machine...at some point02:38:45
