Current behaviour

Guix build for x86_64-apple-darwin fails.

Expected behaviour

The build succeeds.

Steps to reproduce

$ git checkout 94c307b3c0746a08c6135ff38d6f1ad1ed6693bb
$ env SDK_PATH=/home/hebasto HOSTS=x86_64-apple-darwin ./contrib/guix/guix-build

Relevant log output

$ env SDK_PATH=/home/hebasto HOSTS=x86_64-apple-darwin ./contrib/guix/guix-build
Found macOS SDK at '/home/hebasto/Xcode-15.0-15A240d-extracted-SDK-with-libcxx-headers', using...
Checking that we can connect to the guix-daemon...

Hint: If this hangs, you may want to try turning your guix-daemon off and on
      again.

How did you obtain Bitcoin Core

Compiled from source

What version of Bitcoin Core are you using?

master@94c307b3c0746a08c6135ff38d6f1ad1ed6693bb

Operating system and version

Debian Bookworm

Machine specifications

RISC-V SBC.

Has this ever worked on your system? guix shell: error sounds like it is an error unrelated to Bitcoin Core?

Can you use guix and guix shell normally?

Both command work just fine. For example:

$ guix package -i hello
$ guix shell python -- python3

Moreover, every other non-Darwin host is built successfully with ./contrib/guix/guix-build.

I think you'll need to debug this further. It's odd that building for all HOSTS (except one) would work, but building for x86_64-apple-darwin currently works fine, as far as I'm aware (just tested on two different systems).

Both command work just fine. For example:

It's not clear that those are actually invoking the issue-causing behaviour. The error message points to guix container. i.e guix shell --container.

$ uname -m
riscv64
$ guix shell --container --pure hello
$ hello
Hello, world!
$ exit
exit

The issue happens when switch to/form Darwin host. For both invocations

$ env SDK_PATH=/home/hebasto HOSTS="x86_64-w64-mingw32 x86_64-apple-darwin" ./contrib/guix/guix-build

and

$ env SDK_PATH=/home/hebasto HOSTS="x86_64-apple-darwin x86_64-w64-mingw32" ./contrib/guix/guix-build

build for the former host succeeds, then the error happens:

guix shell: error: cannot link profile: '/home/hebasto/.guix-profile' already exists within container

You'll need to try with all the options we pass to shell/container.

The problem was env SDK_PATH=/home/hebasto, which effectively shared my home directory with a Guix container.
