 dramforever | of course nobody ever understand what the switches mean so i've sort of always just removed the sd card and flipped it around until i get u-boot | 18:00:49 |

 rosssmyth | I've not looked, I just assumed that if it worked it would pull and IP address and I could connect via ssh | 18:47:29 |
| rosssmyth | I'll check | 18:47:32 |

| rosssmyth | Oh yeah, I just needed to set the dip switches | 18:56:44 |
| rosssmyth | Thanks! | 18:57:40 |

| rosssmyth | Trying to run nixos-install to get an image onto my VisionFive's NVME drive. It's a pretty minimal image but I did add ripgrep, fd, and helix to it. But it seems to fail the build at "bootstrap-stage4-gcc-wrapper" | 22:17:10 |

| rosssmyth | Is it generally a better idea to cross-compile the image from my x86 machines then upload them to my risc box? I've tried two runs so far and both failed. | 22:19:57 |
| rosssmyth | But building the initial image for the SD card went fine | 22:20:07 |

image.png Sounds to me like an OoM kill. What do the kernel logs say? | 23:03:32 |
| Alex | If the cause is OoM, try building with -j1 | 23:04:18 |
 Tristan Ross | That is 100% an OOM kill | 23:08:47 |

| rosssmyth | okie dokie | 01:01:02 |
| rosssmyth | Retrying with -j 1 | 01:15:28 |
| rosssmyth | Do most people cross-compile or build on host? | 01:15:44 |
| Alex | In reply to @rosssmyth:matrix.org
Do most people cross-compile or build on host? Both are viable. | 01:16:53 |
| rosssmyth | I'm building on host because it means I can use my desktop at the same time. But on host take a very long time | 01:19:51 |
| Tristan Ross | I built on my VF2 | 01:20:36 |
| Tristan Ross | Took about a month | 01:20:40 |
 fgaz | since you have a nvme drive you could use it as swap | 09:51:34 |
| fgaz | and as build directory | 09:52:20 |
| Alex | As a side note, you should definitely not be using tmpfs on /tmp when building NixOS. | 10:25:48 |
