want to run OProfile under. Do ./configure --with-linux=/path/to/kernel/source then make install. This option is no longer oprofile tutorial supported with OProfile 0.9.8 and higher. For 2.6 or higher kernels, how to use oprofile ensure that the kernel has been configured to include OProfile, either built into the kernel or as install oprofile a module. Next, do ./configure --with-kernel-support. As of OProfile 0.9.8, kernel support is assumed, and the --with-kernel-support option is no longer needed nor available. Where can I get

the required libraries ? Most required runtime libraries should already be installed on your system. For building OProfile, you may need to install additional devel packages -- for example, the binutils development package, which provides libiberty and others. On Debian, this package is not installed by default, and is named "binutils-dev". How do I get started ? how to use oprofile linux Read Getting started. How do I reset the profiling data ? For legacy OProfile (i.e., opcontrol-based profiling), use opcontrol --reset, or you can save the session under a name with opcontrol --save
