Do you mean the 'bogus warning about the uninit variable' fix, it does not fix the ld 'undefined reference' error i just git pull'ed and did make, it still fails as below.

Ah, I saw the warning (which ends up being an error for me) and stopped looking. Both of those are because new patches for the first time are calling functions that were previously defined, but not being called. When those functions were initially created, they weren't added to libvirt_private.syms, and later when they were finally used, the reviewer (me) didn't think to look for the entry in libvirt_private.syms because the functions already existed (and of course make check worked for me because I don't build with loadable modules). I just pushed build-breaker patches for both errors.
Thanks Laine, that worked. On 02/02/2012 02:46 AM, Laine Stump wrote:
