Hi,

I'm trying to package MFEM, but I get the following error while building:

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Basically it complains of suspicious ownership or permission.
I looked at the permissions of the contents of the repository when cloning =
it
manually, and nothing seems to be world-writable, as
nix/libstore/build.cc:2373 seems to be trying to protect against.

Regarding the Git warning at the top, I looked in the repository for any
references to Git attributes and ignore files, but did not find any.
I suspect it is looking for the .config directory in $HOME, but the variabl=
e
is unset, of course.

What's more, I tried with url-fetch, and it also results in suspicious
ownership or permission.

I'm at a loss as to what to do.

Can someone give me a hand?

Thanks,
Paul

The package is basically ready now, except for the suspicious ownership
mentioned in the previous patch.
I've tested it on a local copy of MFEM.
(The OpenMPI version is trickier to compile.)

Hi Paul,

Could you try updating guix-daemon?  (You might need to roll back first
to avoid the bug above.)

While fixing
<https://guix.gnu.org/en/blog/2024/fixed-output-derivation-sandbox-bypass-c=
ve-2024-27297/>,
I first pushed a =E2=80=9Cbroken=E2=80=9D fix that led to the problem above=
.  If you
were unlucky and upgraded guix-daemon right at that time (I fixed it
with a followup commit ~24h later), then you have the problem above.

HTH!

Ludo=E2=80=99.
