Some Nix packages installed on Guix System fail to launch with an error referencing GLIBC_PRIVATE

[emacsomancer]

Describe the bug

Some Nix packages installed on Guix System fail to launch with an error referencing GLIBC_PRIVATE. Two examples: gargoyle and deadd-notification-center.

Here's the message for gargoyle:

gargoyle: /nix/store/6w8g7njm4mck5dmjxws0z1xnrxvl81xa-glibc-2.34-115/lib/libpthread.so.0: version `GLIBC_PRIVATE' not found (required by /gnu/store/5h2w4qi9hk1qzzgi1w83220ydslinr4s-glibc-2.33/lib/librt.so.1)

Steps To Reproduce

Steps to reproduce the behavior:

1. install gargoyle or deadd-notification-center from Nix on Guix System
2. try to run either
3. get the error

Expected behavior

Run normally as other Nix packages on top of Guix System.

[hqurve]

Perhaps related to #170897

[emacsomancer]

Is there a fix? Or a decent workaround?

[hqurve]

I think a work around is to either

• set LD_PRELOAD to nixpkgs' libc. Perhaps put it in your .profile. Which if youre managing with nix, you could set to ${glibc}/lib/libc.so.6 (Document how to work around dynamic linking problems caused by glibc updates #170897 (comment))
• set LD_LIBRARY to nixpkgs' glibc. (https://discourse.nixos.org/t/could-we-robustly-protect-against-errors-version-glibc-2-33/18343)

(I have not tested either)

[emacsomancer]

Running env LD_PRELOAD=/nix/store/ayrsyv7npr0lcbann4k9lxr19x813f0z-glibc-2.34-115/lib/librt.so.1 gargoyle gets gargoyle to start up correctly.

The same trick doesn't seem to work for deadd-notification-center, e.g. env LD_PRELOAD=/nix/store/ayrsyv7npr0lcbann4k9lxr19x813f0z-glibc-2.34-115/lib/librt.so.1 deadd-notification-center results in a different error:

/bin/sh: symbol lookup error: /nix/store/ayrsyv7npr0lcbann4k9lxr19x813f0z-glibc-2.34-115/lib/librt.so.1: undefined symbol: __libc_unwind_link_get, version GLIBC_PRIVATE
locale: symbol lookup error: /nix/store/ayrsyv7npr0lcbann4k9lxr19x813f0z-glibc-2.34-115/lib/librt.so.1: undefined symbol: __libc_unwind_link_get, version GLIBC_PRIVATE

[hqurve]

Did using the libc file (instead of librt) fail as well?

[emacsomancer]

If I try env LD_PRELOAD=/nix/store/ayrsyv7npr0lcbann4k9lxr19x813f0z-glibc-2.34-115/lib/lib.so.6 gargoyle, I get:

ERROR: ld.so: object '/nix/store/ayrsyv7npr0lcbann4k9lxr19x813f0z-glibc-2.34-115/lib/lib.so.6' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
gargoyle: /nix/store/6w8g7njm4mck5dmjxws0z1xnrxvl81xa-glibc-2.34-115/lib/libpthread.so.0: version `GLIBC_PRIVATE' not found (required by /gnu/store/5h2w4qi9hk1qzzgi1w83220ydslinr4s-glibc-2.33/lib/librt.so.1)

At least gargoyle works with preloading librt.

[hqurve]

You made a small typo, you have lib instead of libc. The error is saying that the file is not found

[emacsomancer]

You're right. But the non-typo'd one also doesn't work:

$ env LD_PRELOAD=/nix/store/ayrsyv7npr0lcbann4k9lxr19x813f0z-glibc-2.34-115/lib/libc.so.6 gargoyle
gargoyle: /nix/store/6w8g7njm4mck5dmjxws0z1xnrxvl81xa-glibc-2.34-115/lib/libpthread.so.0: version `GLIBC_PRIVATE' not found (required by /gnu/store/5h2w4qi9hk1qzzgi1w83220ydslinr4s-glibc-2.33/lib/librt.so.1)
