@paparodeo:matrix.orgreno i'm trying to build a rust program but getting a link error note: /nix/store/f3k0rdhcd2cx57phx755c2xixgifw5m5-binutils-2.42/bin/ld: /nix/store/n06b8gzyhwn9acggacnzl4yypccn77wp-gcc-13.3.0-lib/lib/libgcc_s.so.1: undefined reference to _dl_find_object@GLIBC_2.35' _dl_find_objectis defined in-lcwhich is in the link flags. build works fine on aarch64 darwin and x64 linux but fails on aarch64 linux. Tried to add-lcinNIX_LDFLAGSandNIX_CFLAGS_COMPILEbut am still getting same error. i assume it might have something to do with-lgcc_scoming before-lc` on the command line but not sure how re-order flags to try. 15:06:32

@paparodeo:matrix.orgreno

can reproduce on aarch64 linux by:

nix-shell -p cargo libudev-zero
cargo new linkerror
cd linkerror
cargo add serialport
cargo build

@qyliss:fairydust.spaceAlyssa RossCan you open a Nixpkgs bug report and @ me (@alyssais)?15:13:58

Can you open a Nixpkgs bug report and @ me (@alyssais)?
thx -- thought maybe i was just doing something obviously wrong, am a rust noob. created: https://github.com/NixOS/nixpkgs/issues/341604 		15:25:23
@qyliss:fairydust.spaceAlyssa Rossthanks, I'll try to look at it next time I'm on aarch15:38:44
@qyliss:fairydust.spaceAlyssa Rossfollowed the repro on x86_64 just to quickly check — I've done a little edit to the issue to mention it also needs pkg-config15:40:33
@qyliss:fairydust.spaceAlyssa Ross

(the --pure flag for nix-shell is helpful to make sure you've got all the dependencies like that)

thx! -- adding pkg-config solves link issue for me on aarch64 linux 		15:48:25

@qyliss:fairydust.spaceAlyssa Rossokay, wasn't expecting that to actually be the problem!15:52:27

@svrana:matrix.orgsvranaI'm attempting to package up a small rust program that relies on pw-cli from the pipewire library at runtime. Is there a way to specify this in buildRustPackage?16:09:25
@k900:0upti.meK900 Use makeWrapper 16:12:16
@k900:0upti.meK900Or patch the source16:12:18
@k900:0upti.meK900But also why would you ever16:12:21
@k900:0upti.meK900You can just call libpipewire16:12:32

@el125:matrix.orgeelsaHi all! I'm trying to package a rust package, but keep running into this problem18:55:00

@el125:matrix.orgeelsaCurious as to whether ya'll might know what to do, or what steps I can take - thanks a ton! :D18:55:13
@k900:0upti.meK900Why are you trying to use a Cargo.lock from your Downloads directory18:57:30
@el125:matrix.orgeelsaI don't know, that's just what's happening when I try to build it18:58:06
@emilazy:matrix.orgemily you need to track Cargo.lock in Git 18:58:41
@el125:matrix.orgeelsaimage.png
Download image.png		18:58:42
@emilazy:matrix.orgemilybecause flakes only look at tracked files18:58:47
@el125:matrix.orgeelsaah that's really helpful! Can i ask if you have an example of that? I'm relatively new to Nix.18:59:23
@k900:0upti.meK900Are you in a git repo?19:00:47
