Weird. I don't have access to Rawhide at the moment so I can't recreate. It builds fine for me on Fedora 29. But I don't see how those warnings could get enabled: -Wsign-compare -Wunused-parameter. Can you "make clean" and do "make V=1 tools/objtool" to show the actual flags? The reported warnings do seem reasonable though, maybe we should fix them regardless and explicitly enable the warnings. -- Josh
