PAPI Forum

Hi,

I am compiling linux kernel 2.6.32-71.el6.x86_64 in order to patch "perfctr" driver but while compilation(make CONFIG_DEBUG_SECTION_MISMATCH=y binrpm-pkg 2> ../build-err.log | tee ../build-out.log).
It produces following error.
scripts/kconfig/conf -s arch/x86/Kconfig

SYMLINK include/asm -> include/asm-x86

Please suggest how this error can be resolved?
Perfctr version:perfctr-2.6.40 PaPI version:papi-4.1.4
Also share the link for newer version download.
Thanks in advance,

If you are running on a 2.6.32 kernel you do not need to compile perfctr. You can use PAPI with the "perf_event" subsystem included in your kernel.
