Does anybody now any other flag that might influence this? Is it normal (never used readdir_r myself) that it is only defined in multi-threading-mode? Should we instruct bbv1 to compile the
Yes that seems eminently reasonable (that readdir_r only be prototyped/available if -mt is supplied).
boost.filesystem always with the -mt flag on hpux ?
Well, there is code in libs/filesystem/src/operations_posix_windows.cpp that attempts to detect if it is being compiled with multi-threading enabled: # if defined(_POSIX_THREAD_SAFE_FUNCTIONS) \ && defined(_SC_THREAD_SAFE_FUNCTIONS) \ && (_POSIX_THREAD_SAFE_FUNCTIONS+0 >= 0) Presumably aCC sets these macros incorrectly, or this code is not correct. Maybe the check should be for >0? Perhaps you can check what _POSIX_THREAD_SAFE_FUNCTIONS is defined to on aCC both with and without -mt? On Linux 2.4.21 + gcc 3.3.4, I get 200112 both with -pthread and without. #include <pthread.h> #include <iostream> int main () { std::cout << _POSIX_THREAD_SAFE_FUNCTIONS << std::endl; } -- Caleb Epstein caleb dot epstein at gmail dot com
