Re: [libvirt] [PATCH RFC] libxl: fix paths in capability string

On 01/06/2015 09:12 AM, Wei Liu wrote: Why can't you just make '--with-libxl=/path/to/alt' work? That is, --with-libxl=yes uses a default (which matches the prefix where LIBVIRT will be installed [1]), --with-libxl=no turns it off, and specifying a path says to use that path. Then you don't need to add a new option. [1] The assumption generally is that whoever is building libvirt has also built libxl to be installed in the same location - which is a nicer default than hard-coding a /usr/local default that libxl uses in isolation. Of course, libvirt also defaults to /usr/local in isolation, so if you don't specify anything at all, then ./configure will see that libvirt is going into /usr/local and will therefore default to looking for libxl also in /usr/local; but for a distro packager, it is nicer to have the mere specification of --prefix switch all other relative defaults to play nicely with everything else in the distro. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
