[libvirt] [gnulib PATCH 0/2] Work around glibc 2.25 deprecation warnings
by Eric Blake 15 Sep '16

15 Sep '16

Fedora rawhide builds of libvirt.git at commit d53fa838^ failed due to the new glibc 2.25 deprecation warning for use of major() from just <sys/types.h>; I also found that the same warning is provoked by gnulib's mountlist module. Libvirt commit d53fa838 was a temporary hack to work around the problem, and I will be reverting that and updating to newer gnulib once this goes in. I've tested that libvirt on Fedora rawhide with d53fa838 reverted and gnulib updated to this commit was once again able to build. Comments welcome, particularly for my choice of wording in documentation changes. The final push will differ slightly from this, especially if the autoconf patch going in first changes slightly due to review there, but this should give a good idea of the fix.

Okay, I have confirmed that this prime-the-cache idea DOES work, using libvirt.git commit 419bc8cf (one commit prior to d53fa838 which installed a hack into libvirt to force the use of -Werror for the duration of AC_HEADER_MAJOR [1]). By itself, './configure' succeeds but leaves MAJOR_IN_SYSMACROS undefined, which results in a build failure later in libvirt; but when run as './configure ac_cv_header_sys_types_h_makedev=no', MAJOR_IN_SYSMACROS gets defined and the build succeeds. I want to remove the libvirt hack (not all compilers understand -Werror, even if libvirt is only ever built by gcc or clang), and my experiment was enough to prove that: 1. distros that provide a config.site file can use this file to avoid the problem, even for packages that have not yet rebuilt with a new-enough autoconf to fix the issue 2. autoconf and gnulib should indeed be fixed to probe for <sys/sysmacros.h> _prior_ to probing for whether makedev() exists in <sys/type.h>, rather than the 2.69 logic of only checking for <sys/sysmacros.h> if makedev() was not found earlier. Of course, the libvirt hack should not be reverted until autoconf and gnulib have the final solution in place. > > Meanwhile, even without an autoconf release scheduled, I am currently > working on patching the existing autoconf macro and documentation to > match the current situation.

Where autoconf was wrong was that it was not even probing for the existence of <sys/sysmacros.h> if it found that <sys/types.h> was enough to pollute the namespace with the three macros. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
