please also update the warning, as now it's not obvious you need to install also bz2 libs (bzip2-devel on Fedora) for dwarf support.. we already have check for lzma thanks, jirka [jolsa@krava perf]$ make BUILD: Doing 'make -j4' parallel build Auto-detecting system features: ... dwarf: [ OFF ] ... glibc: [ on ] ... gtk2: [ on ] ... libaudit: [ on ] ... libbfd: [ on ] ... libelf: [ on ] ... libnuma: [ on ] ... libperl: [ on ] ... libpython: [ on ] ... libslang: [ on ] ... libunwind: [ on ] ... libdw-dwarf-unwind: [ on ] ... zlib: [ on ] ... lzma: [ on ] config/Makefile:267: 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 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
