Huh, I remember seeing different error when trying this (although I'm using gcc). However, I suspect '-Wl,-z -Wl,defs' arguments are problem. We add them onto linker cmd line. You can try applying this patch and see if it helps: diff --git i/configure.ac w/configure.ac index 18587270e6..e23c0e4c22 100644 --- i/configure.ac +++ w/configure.ac @@ -237,7 +237,6 @@ LIBVIRT_COMPILE_WARNINGS LIBVIRT_COMPILE_PIE LIBVIRT_LINKER_RELRO LIBVIRT_LINKER_NO_INDIRECT -LIBVIRT_LINKER_NO_UNDEFINED LIBVIRT_ARG_APPARMOR LIBVIRT_ARG_ATTR Michal
It works. Thank you very much!!! On Tue, Apr 10, 2018 at 2:40 PM, Michal Privoznik <mprivozn@redhat.com> wrote:
