Hello, perf record no samples in perf.data on an IBM x3250M5. perf stat is OK (in that way that it displays some stats). Before digging into the hardware, let us check together if my 'perf' compilation fulfills all requirements :
I tried to compile the perf inside a linux kernel 3.19 from kernel.org. Compilation is made on a Centos 6.6 with following info: [root@localhost Desktop]# cat /proc/version Linux version 2.6.32-504.23.4.el6.i686 (mockbu...@c6b9.bsys.dev.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-11) (GCC) ) #1 SMP Tue Jun 9 18:09:42 UTC 2015 [root@localhost Desktop]# cd /usr/src/kernels/linux-3.19/tools/perf/ [root@localhost perf]# make BUILD: Doing 'make -j1' parallel build config/Makefile:128: The path 'python-config' is not executable. config/Makefile:390: No libunwind found.

FYI, I saw no error message during compilation. Thanks.
