With recent binutils I get: perf % make Makefile:668: No bfd.h/libbfd found, install binutils-dev[el]/zlib-static to gain symbol demanglin That happens because bfd.h now contains: I've reopened a bug in the hope that this check will be deleted: http://sourceware.org/bugzilla/show_bug.cgi?id=14243 But in the meantime, the following patch fixes the problem Signed-off-by: Markus Trippelsdorf <markus@trippelsdorf.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: Mike Frysinger <vapier@gentoo.org> Cc: Paul Mackerras <paulus@samba.org> Link: http://lkml.kernel.org/r/20120919072902.GA262@x4 Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
