Something like this ? ;) commit 350583c859deaaddc98d7319e1c2ad649e4d3e83 Author: Eric Blake <eblake redhat com> Date: Wed Jun 13 10:09:39 2012 -0600 build: hoist qemu dependence on yajl to configure Commit 6e769eba made it a runtime error if libvirt was compiled without yajl support but targets a new enough qemu. But enough users are hitting this on self-compiled libvirt that it is worth erroring out at compilation time, rather than an obscure failure when trying to use the built executable. * configure.ac: If qemu is requested and -version works, require yajl when qemu version is new enough. * src/qemu/qemu_capabilities.c (qemuCapsComputeCmdFlags): Add comment.
