| |
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. --- tools/perf/builtin-sched.c | 1 + 1 file changed, 1 insertion(+)
