 Šimon Brandner | So the problem is that the build.rs thingy is failing to find the file it generated (and I indeed cannot find it in /tmp/nix-build-app-0.0.1.drv-0) | 16:47:55 |
| Šimon Brandner | It could be an issue with OUT_DIR not being set correctly... | 16:50:32 |
 quapka4 | Hi folks, is it not possible to directly change the sources in $src during any of the phases? Imagine I need to add a generic target to Makefile, so I wanted to do something like:
mySource = ./extraMakeTarget.txt
<somePhase> = ''
cat $mySource >> $src/makefile
'';
But I am getting a Permission Denied error.
| 17:08:40 |
| quapka4 | I don't/can't easily use patches because the makefile can have various structure depending on the version of the package. | 17:09:14 |
| quapka4 | I assumed that during the phases I kinda have a full access to whatever sources I have, because my changes through any phase end up in the resulting hash anyway. | 17:12:05 |

You actually do, but the source (refered to by $src) is still in the read-only nix store. You probably want to change the upacked source, which should be in the working directory of the builder | 17:17:46 |

| quapka4 | So, change $src to $sourceRoot works. | 17:20:33 |
| quapka4 | And I guess postUnpack would be the appropriate place. | 17:23:26 |

It could be an issue with OUT_DIR not being set correctly... Trying to print it makes a bit confused... When building using cargo, I see /home/..., when using nix build, I see /build/... | 17:29:38 |
 samasaur | Pretty sure that is because when you are using nix build the build is run as a nixbld user, and their home directories are not under /home | 19:09:25 |

And I guess postUnpack would be the appropriate place. postPatch or prePatch, I'd say | 05:31:16 |

| quapka4 | Hi, a simple thing :D. I have a flake.nix that builds on my NixOS machine, but when I tried to build that flake on another non-NixOS machine that has Nix installed with nix-user-chroot the build fails on one particular package (libgpg-error). What is the reasonable way to debug this? | 08:29:52 |
| quapka4 | I hope it's some mismatch of channels or some version or something, because this hassle with "runs on my machine" is exactly something I wanted to avoid when diving into Nix :D | 08:30:43 |

What is the reasonable way to debug this? if the store path is the same then it's not some channel or version mismatch | 08:33:18 |
| dramforever | it could just be something in libgpg-error that works differently in a chroot... unfortunately it's also basically an ad-hoc process to see what went wrong | 08:34:06 |
| quapka4 | Well, nix-user-chroot gives me /nix/store and my NixOS also has /nix/store. | 08:34:56 |
| dramforever | oh i mean the path of that thing that "builds" | 08:35:16 |
| dramforever | how are you running anything? full command and logs? | 08:35:24 |
| dramforever | it should fail at the end something like for full logs run nix log /nix/store/somethingsomething.drv | 08:35:53 |
| quapka4 | Just nix build '.?submodules=1'. | 08:36:00 |
| dramforever | if that long something is the same it's not a channel or version mismatch | 08:36:03 |
| dramforever | oh yeah sorry there's no way to know what the success side looks like 🤦 | 08:36:38 |
| dramforever | In reply to @quapka4:matrix.org
Just nix build '.?submodules=1'. how about nix eval --raw '.?submodules=1' on both sides | 08:37:11 |
