I've been trying to get Nagios to use the pthreads implementation from GNU's PTH library rather than FreeBSD's. Even a trivial program, such as: #include <stdio.h> #include <sys/types.h> #include <pthread.h> produces syntax errors: $ cc -c -I/usr/local/include/pth x.c In file included from x.c:3: /usr/local/include/pth/pthread.h:285: error: conflicting types for 'pthread_t' /usr/include/sys/_pthreadtypes.h:64: error: previous declaration of 'pthread_t' was here /usr/local/include/pth/pthread.h:286: error: conflicting types for 'pthread_attr_t' /usr/include/sys/_pthreadtypes.h:65: error: previous declaration of 'pthread_attr_t' was here /usr/local/include/pth/pthread.h:288: error: conflicting types for 'pthread_once_t' /usr/include/sys/_pthreadtypes.h:71: error: previous declaration of 'pthread_once_t' was here /usr/local/include/pth/pthread.h:289: error: conflicting types for 'pthread_mutexattr_t' /usr/include/sys/_pthreadtypes.h:67: error: previous declaration of 'pthread_mutexattr_t' was here /usr/local/include/pth/pthread.h:290: error: conflicting types for 'pthread_mutex_t' /usr/include/sys/_pthreadtypes.h:66: error: previous declaration of 'pthread_mutex_t' was here /usr/local/include/pth/pthread.h:291: error: conflicting types for 'pthread_condattr_t' /usr/include/sys/_pthreadtypes.h:69: error: previous declaration of 'pthread_condattr_t' was here /usr/local/include/pth/pthread.h:292: error: conflicting types for 'pthread_cond_t' /usr/include/sys/_pthreadtypes.h:68: error: previous declaration of 'pthread_cond_t' was here /usr/local/include/pth/pthread.h:293: error: conflicting types for 'pthread_rwlockattr_t' /usr/include/sys/_pthreadtypes.h:73: error: previous declaration of 'pthread_rwlockattr_t' was here /usr/local/include/pth/pthread.h:294: error: conflicting types for 'pthread_rwlock_t' /usr/include/sys/_pthreadtypes.h:72: error: previous declaration of 'pthread_rwlock_t' was here It seems that revision 1.92 of sys/types.h now includes sys/_pthreadtypes.h, which conflicts with PTH's pth/pthread.h. Is there anyway to use GNU PTH's pthread implementation on FreeBSD 6.1?
