Hello,

Just installed binary x86-64 nix on Arch Linux as per instructions here:


The install for root when well and the hello sample package installed
fine. Then I went to setup my user as described here:


but got a segfault at:

$ guix package -i glibc-locales

and in fact even just

$ guix

I don't know if this backtrace is useful but here it it:

Is LD_LIBRARY_PATH or LD_PRELOAD set in your environment?

What happens if you run:

env -i `type -P guix` --help

What does “info files” say in GDB?

Thank you for the bug report!

This was set:

LD_LIBRARY_PATH=/home/myles/GNUstep/Library/Libraries:/usr/lib

so I uninstalled GNUstep and rebooted, LD_LIBRARY_PATH is unset and this
works:

$ guix package -i glibc-locales

$ env -i `type -P guix` --help
zsh: bad option: -P
Usage: env [OPTION]... [-] [NAME=VALUE]... [COMMAND [ARG]...]
Set each NAME to VALUE in the environment and run COMMAND.

Mandatory arguments to long options are mandatory for short options too.
-i, --ignore-environment start with an empty environment
-0, --null end each output line with NUL, not newline
-u, --unset=NAME remove variable from the environment
--help display this help and exit
--version output version information and exit

A mere - implies -i. If no COMMAND, print the resulting environment.

P.S. now firefox gives me a segfault, I think there are other issues here.

Then something like:

env -i `which guix` --help

Anyway, the rest of your message confirms my intuition.

Thanks,
Ludo’.
