[libvirt] setlocale problems / "initialization failed" in Rawhide

https://bugzilla.redhat.com/show_bug.cgi?id=1312688 When you upgrade from F23 to current Rawhide, you don't get any "language pack" installed. It turns out this breaks many things including libvirtd which no longer starts up: $ ./daemon/libvirtd --help /home/rjones/d/libvirt/daemon/.libs/lt-libvirtd: initialization failed Simply installing glibc-langpack-en is sufficient to fix this, but I was wondering if we should try to make libvirt work anyway. The failure comes from setlocale (LC_ALL, "") returning NULL. The attached test program prints: $ ./test setlocale failed, errno=No such file or directory Also attached is the strace output so you can see what files it is looking for. Seems like solutions to this include: - Make libvirt in Fedora depend on glibc-langpack-en. - Ignore the return value from setlocale. It seems unlikely that we really care if setlocale fails. I'm not even sure what it does. Note that virsh already ignores setlocale: if (!setlocale(LC_ALL, "")) { perror("setlocale"); /* failure to setup locale is not fatal */ } Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com virt-top is 'top' for virtual machines.
