>Description:
Tru64 5.1a is more strict than other versions of Tru64 when
compiling a threaded program.
extract of pthreads.h file on Tru64 5.1:
/*
* Enable reentrant errno.h. HOWEVER: this is here only to avoid breaking old
* (and incorrect) code that assumes it's here. This will only work if
* <pthread.h> is the first header file included, and it is always far better
* to avoid such assumptions. You should always define _REENTRANT on the
* command line, usually by using "cc -pthread" or "cxx -pthread", to be sure
* that it will be available for all header files.
*/
#ifdef _PTHREAD_ENV_UNIX
# ifndef _REENTRANT
# define _REENTRANT 1
# endif
#endif
extract of pthreads.h file on Tru64 5.1a:
#ifdef _PTHREAD_ENV_UNIX
# ifndef _REENTRANT
# error "Please compile the module including pthread.h with -pthread"
# endif
#endif
>How-To-Repeat:
./configure , then notice that mit-pthreads is getting built
