| matthewcroughan - nix.how | this is for gnu-musl-llvm | 17:46:22 |
| matthewcroughan - nix.how | so cross, llvm, musl | 17:46:27 |
 Alyssa Ross | uhh, Clang bug? | 17:51:25 |
| Alyssa Ross | oh never mind that's g-ir-scanner | 17:52:33 |
| Alyssa Ross | not Clang | 17:52:39 |
| matthewcroughan - nix.how | Only happens in this one context, and not in the other contexts | 18:00:42 |
| matthewcroughan - nix.how | So native, native-musl native-llvm-musl all fine | 18:01:11 |
| matthewcroughan - nix.how | gnu-musl I think is fine too, so must be the llvm | 18:01:39 |
| Alyssa Ross | I would:
- Check with glib that this is definitely not a glib bug (doesn't look like it)
- Report to LLVM
hardeningDisable = [ "stackprotecter" ]; in glib with a link to the LLVM bug report

| matthewcroughan - nix.how | Hmm, I added hardeningDisable to an overlay, it didn't seem to work exactly | 17:21:47 |
| matthewcroughan - nix.how | Is this another case where you can't overlay it, and you have to fix it in nixpkgs because of bootstrap stuff? | 17:22:01 |
| matthewcroughan - nix.how | like with bash | 17:22:04 |
| matthewcroughan - nix.how | I notice the build graph starts off with a glib that does get fixed, and then ends on another glib which is not fixed | 17:22:22 |

| Alyssa Ross | hmm, maybe it's from some library glib links or something, then? maybe you can catch it in a debugger | 18:49:00 |

 Puna | π | 05:35:11 |
| amaan | hey π | 05:35:51 |
| Puna | so ArchPOWER's ppc64 build has a 64k page size? have you run into any issues with that, or know of any patches they're applying for that to work? | 05:36:53 |
| Puna | i've only ever tested 4K, cus that's what Debian uses | 05:37:21 |
| amaan | yeah i ran into issues building jemalloc which is why i submitted that patch, tho it seems to vary by distro i guess, tbf I just got access to this machine today and figured I'd build a nix iso on it to try it out | 05:37:33 |
| Puna | ahhh oki! | 05:37:48 |
| Puna | do you know how the machine's firmware looks for bootable media? i have some PRs and a branch in my fork that works for making a PowerMac (and maybe CHRP?) compatible ISO, but i don't have access to anything newer than ~ POWER4. | 05:38:57 |
| Puna | the branch in question, if you wanna give that a try: https://github.com/OPNA2608/nixpkgs/tree/wip/ppc64-installer | 05:42:12 |
| amaan | i guess gentoo, suse, and fedora also use 64kb page sizes:
https://github.com/gentoo/genkernel/blob/master/arch/ppc64/arch-config#L26
https://github.com/openSUSE/kernel-source/blob/master/config/ppc64le/default#L559
https://src.fedoraproject.org/rpms/kernel/blob/rawhide/f/kernel-ppc64le-fedora.config#_5366
also in the ppc kconfig it defaults to 64kb in certain scenarios interestingly - https://github.com/torvalds/linux/blob/master/arch/powerpc/Kconfig#L853 | 05:42:52 |
| amaan | i am not sure tbh, i just found a zulip that offers free machines to ssh to and dev on tho...they are power8 btw | 05:43:24 |
