Hi Richard, As per your suggestion we removed pango-devel and build was successful. Thank you! After the delivery, our customer reported another error related to virt-resize as below: virt-resize: error: libguestfs error: internal_feature_available: dispatch_incoming_message: unknown procedure number 458, set LIBGUESTFS_PATH to point to the matching libguestfs appliance directory Regards, Abinaya -----Original Message----- From: Richard W.M.

Which is one way to fix it, but I suppose it depends on if you need virt-p2v ... As the error message says, automake is missing. I suppose removing pango also removed automake for whatever reason, or you removed or changed the version of automake while you were removing pango. I cannot reproduce the original problem right now, but I'm looking at it.
