 Stas | Mine is having flaky ram slots. Will burn the apple test cd to test it | 07:31:17 |
| Stas | It just hangs, but after wiggling the sticks the problem goes away for a while | 07:32:04 |
 lorne | I just returned from the junk shop with a G4 PowerMac3,6. This is probably going to be more interesting to get going. | 08:24:29 |

Mine is having flaky ram slots. Will burn the apple test cd to test it Try cleaning the contacts with isopropyl | 09:29:28 |
| Artturin | Wiggling the sticks sounds like it's rubbing away corrosion(or similar) | 09:30:25 |
| Stas | I tried with a more proper contact cleaner, need to retry some day | 12:35:02 |

 Puna | LMK when you get to the point where you'd try to make an installer ISO. I'm interested to know how booting differs on that hardware compared to my G5. | 14:22:51 |
| lorne | For my G5 I've been assembling a symlink tree of: grub image, kernel, vmlinux, squashfs, and just scp-ing it directly to an Apple Partition Map / HFS+ volume on a usb stick and booting over usb with the regular probe-usb boot usb3/disk:3,\grub\grub.img. I was going to try that again once everything builds (libressl is sad). | 15:04:37 |

| Puna | https://github.com/NixOS/nixpkgs/pull/486572 and https://github.com/NixOS/nixpkgs/pull/488831 should allow you to build an ISO via nixos module stuff, write it to a USB / burn to a disc, and either boot it from the mac's multiboot menu thingy or via the tbxi entry point in openfirmware | 15:56:41 |
| Puna | https://github.com/OPNA2608/nixpkgs/tree/wip/ppc64-installer is a nixpkgs tree where i collect all such fixes/additions that i have submitted, and rebase them on nixos-unstable every once in awhile (after checking that everything still builds and boots). the newworldmac-nixos-installer.nix file in the repo root can be used as the config for the iso. example command (run on the hardware itself):
puna@Yubel ~/D/nixpkgs (wip/ppc64-installer-testing)> env \
"NIX_PATH=nixpkgs=$PWD:nixos-config=$PWD/newworldmac-nixos-installer.nix" \
nom-build \
--option allow-import-from-derivation false \
--no-out-link \
--max-jobs 1 --cores 2 \
./nixos -A config.system.build.images.iso
YMMV when doing cross

|  kiffeuse4life67 changed their display name from missbehaves to kiffeuse4life67. | 07:45:26 |
| lorne | I have grub and the kernel and initrd loading from a usb stick, but no usb so it's not booting and not responding to the keyboard. I guess I'm missing the usb driver. | 14:20:25 |

| lorne | upon closer inspection, udevd and journald are segfaulting | 11:17:12 |
| lorne | turning off systemd in init was enough to boot to all the way to a shell, but I'm no further ahead. keyboard input produces squares, and networking isn't up so I can't ssh in either. | 16:26:30 |

| richarddodd | Hey - I'm trying to do some cross x64 -> aarch64 and am finding some packages aren't building (RN it's tree-sitter). Is there a guide somewhere for how to go about debugging packages in the nixpkgs repo? | 14:20:24 |
 K900 | There's really no simple answer here | 14:20:51 |
| K900 | Very few upstreams actually test cross compilation | 14:20:59 |
| K900 | So the process is usually "look at the build error really hard and try to figure out what's going wrong" | 14:21:17 |
| richarddodd | I'm happy to debug the build - I just need to figure out how to go from nixpkgs to a shell.nix or similar. | 14:21:35 |
