Hi,

The build directory name is very long, which means that we are a likely
to hit the kernel=E2=80=99s limitation on the length of socket file names, =
as in
the snippet above.

What does this command:

  grep ac_cv_guix_test_socket_file_name_length config.log

return?

At configure time, one normally gets a warning:

  socket file name limit may be exceeded when running tests

(This is not an error because there=E2=80=99s no problem if you don=E2=80=
=99t run =E2=80=98make
check=E2=80=99.)

In your case I think you would have to build from a shorter directory.

HTH,
Ludo=E2=80=99.
