For the latest perf core tree: (git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git), in util/unwind.c line 29 includes "perf_regs.h". That means compiler will search for this header file in current directory, so, gcc will puts the following error messages:
util/unwind.c: In function ‘access_mem’: util/unwind.c:400:50: error: ‘PERF_REG_SP’ undeclared (first use in this function) util/unwind.c:400:50: note: each undeclared identifier is reported only once for each function it appears in util/unwind.c: In function ‘unwind__get_entries’: util/unwind.c:562:41: error: ‘PERF_REG_IP’ undeclared (first use in this function) Changing #include "perf_regs.h" to #include <perf_regs.h> will fix the error.
