I can't get cpupower to compile anymore now that it made its way to linux-next:
[/linux/tools/power/cpupower]$ make
CC lib/cpufreq.o
[...]
make[1]: Entering directory '/linux/tools/power/cpupower/bench'
CC main.o
CC parse.o
parse.c: In function ‘prepare_config’:
parse.c:224:4: warning: implicit declaration of function ‘strlcpy’
[-Wimplicit-function-declaration]
strlcpy(config->governor, val,
^
CC system.o
CC benchmark.o
CC cpufreq-bench
.//parse.o: In function `prepare_config':
/linux/tools/power/cpupower/bench/parse.c:224: undefined reference
to `strlcpy'
collect2: error: ld returned 1 exit status
Makefile:25: recipe for target 'cpufreq-bench' failed
make[1]: *** [cpufreq-bench] Error 1
make[1]: Leaving directory '/linux/tools/power/cpupower/bench'
Makefile:258: recipe for target 'compile-bench' failed
make: *** [compile-bench] Error 2
Does it need anything special to make?
Greetings!
