Subject: [PATCH] Fix perf build failure on glibc trunk
Date: Wed, 4 Apr 2012 10:45:27 +0200
Message-ID: <20120404084527.GA294@x4> (raw)

On a system running glibc trunk perf doesn't build:

    CC builtin-sched.o
builtin-sched.c: In function ‘get_cpu_usage_nsec_parent’:
builtin-sched.c:399:16: error: storage size of ‘ru’ isn’t known
builtin-sched.c:403:2: error: implicit declaration of function ‘getrusage’ [-Werror=implicit-function-declaration]
builtin-sched.c:403:2: error: nested extern declaration of ‘getrusage’ [-Werror=nested-externs]
builtin-sched.c:403:18: error: ‘RUSAGE_SELF’ undeclared (first use in this function)
builtin-sched.c:403:18: note: each undeclared identifier is reported only once for each function it appears in
builtin-sched.c:399:16: error: unused variable ‘ru’ [-Werror=unused-variable]
cc1: all warnings being treated as errors

Fix it by including sys/resource.h.
