[PATCH v4 2/6] perf tools: configure shell path at compile time
From: Irina Tirdea
Date: Mon Oct 15 2012 - 19:35:01 EST
From: Irina Tirdea <irina.tirdea@xxxxxxxxx>
Shell path /bin/sh is hardcoded in various places in perf. Android has a
different folder structure and does not have /bin/sh.
Set the shell path at compile time in the Makefile by setting PERF_SHELL_PATH.
By default it is set to /bin/sh.
