The context is that I am trying to build and test the GCC 9.2.0 compiler, which was recently released, on a number of different platforms. Some platforms have a very old GLIBC (version 2.11.3), so I am also trying to install GLIBC 2.30. To do that, I am also installing the linux-5.2 headers, which also requires a recent version of sed. Apparently, I need sed to be successful in making symbolic links before the GLIBC build will work.

Insufficient details - you didn't tell us what your operating system was. It may be a bug in your libc, or a weakness in the gnulib test that is trying to determine if your libc is POSIX-compliant. The correct fix will be updating gnulib (either to work around your broken libc, or to fix the broken assumption in the gnulib test), and then releasing a new sed with updated gnulib. > > Is the test failure serious? But in the meantime, how often do you really expect sed to be creating symlinks? This is probably safe to ignore in the context of using your just-built sed. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3226 Virtualization: qemu.org | libvirt.org
