on Debian 13 to build version 6.1.5-1 from source code via pwre.

Hi, Claes

build version 6.1.5-1 from source code via pwre.
running pwre build_all_modules, got error: 

rt_thread.c:75:8: error: redefinition of ‘struct sched_attr’
   75 | struct sched_attr {
      |        ^~~~~~~~~~

what did I do wrong?
 

Hi Wei,

glibc has been modified in Debian 13 and now defines struct sched_attr. Edit src/lib/rt/src/rt_thread.c and add the #if and #endif statements.

#if __GLIBC__ * 100 + __GLIBC_MINOR__ < 241
struct sched_attr {
uint32_t size;

uint32_t sched_policy;
uint64_t sched_flags;

/* SCHED_NORMAL, SCHED_BATCH */
int32_t sched_nice;

/* SCHED_FIFO, SCHED_RR */
uint32_t sched_priority;

/* SCHED_DEADLINE (nsec) */
uint64_t sched_runtime;
uint64_t sched_deadline;
uint64_t sched_period;

/* Utilization hints */
uint32_t sched_util_min;
uint32_t sched_util_max;
};

int sched_setattr(pid_t pid, const struct sched_attr* attr, unsigned int flags)
{
return syscall(__NR_sched_setattr, pid, attr, flags);
}

int sched_getattr(
pid_t pid, struct sched_attr* attr, unsigned int size, unsigned int flags)
{
return syscall(__NR_sched_getattr, pid, attr, size, flags);
}
#endif
