Please install libunwind-dev[el] >= 0.99 Makefile:537: No libdw.h found or old libdw.h found or elfutils is older than 0.138, disables dwarf support. Please install new elfutils-devel/libdw-dev Makefile:567: No libaudit.h found, disables 'trace' tool, please install audit-libs-devel or libaudit-dev Makefile:580: newt not found, disables TUI support. Please install newt-devel or libnewt-dev Makefile:752: No bfd.h/libbfd found, install binutils-dev[el]/zlib-static to gain symbol demangling Actually - I hadn't noticed these warnings before. After installing libdw-dev - the perf build completed successfully. Perhaps this should be fatal, rather than a warning?
