For APR 1.5.2 on OpenBSD 6.0 we have this: #define APR_USE_SHMEM_MMAP_TMP 0 #define APR_USE_SHMEM_MMAP_SHM 0 #define APR_USE_SHMEM_MMAP_ZERO 0 #define APR_USE_SHMEM_SHMGET_ANON 0 #define APR_USE_SHMEM_SHMGET 1 #define APR_USE_SHMEM_MMAP_ANON 1 #define APR_USE_SHMEM_BEOS 0 #define APR_USE_FLOCK_SERIALIZE 0 #define APR_USE_SYSVSEM_SERIALIZE 1 #define APR_USE_POSIXSEM_SERIALIZE 0 #define APR_USE_FCNTL_SERIALIZE 0 #define APR_USE_PROC_PTHREAD_SERIALIZE 0 #define APR_USE_PTHREAD_SERIALIZE 1 The pthread functions pthread_cond_timedwait() and pthread_mutex_timedlock() mentioned earlier in this discussion both exist. Once the defaults are changed on APR trunk, I can test APR trunk on OpenBSD 6.0 (and 6.1, due for release May 1). If anything is missing I can poke OpenBSD developers who are working on pthreads and try to get them to add interfaces APR needs. I can't say anything about other BSDs, I'm afraid. I don't have the time to keep up with all of them.
