Hi guys, I spend some time on researching the project and have some results. Based on the results, I can split the project into multiple parts and expect to complete the project in divide-and-concur way.
I found a lot of building errors in the posix benchmark are because of compiler settings. Some variables are defined and never used, some other variables are set and not used. In the makefile of the posix benchmark, it used -Werror and -Wall as the flags, which will report those cases as errors. After disabling the flags, I can classify all remaining errors into multiple classes, which are listed below. In each class, it requires to provide a particular macro, function or some data structures. I will continue to read related code base and find the best way to solve all those problems. By the way, http://nxr.netbsd.org/ is super helpful to view kernel code, thanks Christos for recommending. timers: _SC_TIMER_MAX _SC_CPUTIME _SC_THREAD_CPUTIME _SC_DELAYTIMER_MAX CLOCK_PROCESS_CPUTIME_ID CLOCK_THREAD_CPUTIME_ID clock_getcpuclockid getdate strptime daylight timezone pthread_getcpuclockid struct timespec pthreads: PTHREAD_PRIO_INHERIT PTHREAD_PRIO_NONE PTHREAD_PRIO_PROTECT PTHREAD_STACK_MIN PTHREAD_ONCE_INIT STACKSIZE pthread_barrierattr_getpshared pthread_barrierattr_setpshared pthread_mutexattr_setpshared pthread_mutexattr_getpshared pthread_condattr_setpshared pthread_condattr_getpshared pthread_condattr_setclock pthread_condattr_getclock pthread_mutexattr_getprioceiling pthread_mutexattr_setprioceiling pthread_mutexattr_getprotocol pthread_mutexattr_setprotocol pthread_rwlockattr_getpshared pthread_rwlockattr_setpshared pthread_mutex_getprioceiling pthread_mutex_timedlock pthread_setaffinity_np pthread_getattr_np scheduler: SCHED_SPORADIC signals: SIGPOLL SIGRTMIN SIGRTMAX SIGNAL SIGSTKSZ SIG_INVALID SIGTOTEST _SC_REALTIME_SIGNALS _SC_SIGQUEUE_MAX SA_ONSTACK SA_RESETHAND SA_RESTART SA_NODEFER SS_ONSTACK SS_DISABLE MINSIGSTKSZ struct sigstack stack_t bsd_signal killpg sigaltstack_test sigaltstack sighold sigignore siginterrupt sigpause sigrelse sigset mmap: POSIX_TYPED_MEM_ALLOCATE POSIX_TYPED_MEM_ALLOCATE_CONTIG POSIX_TYPED_MEM_MAP_ALLOCATABLE struct posix_typed_mem_info posix_mem_offset posix_typed_mem_get_info posix_typed_mem_open aio struct rlimit cpuset CPU_ZERO CPU_SETSIZE CPU_SET cpu_set_t semaphore _SC_SEM_NSEMS_MAX features.h
