Re: [boost] [filesystem] Can't compile on Tru64/gcc

The code in question is:

# if defined(_POSIX_THREAD_SAFE_FUNCTIONS) \ && defined(_SC_THREAD_SAFE_FUNCTIONS) \ && _POSIX_THREAD_SAFE_FUNCTIONS >= 0 if ( ::sysconf( _SC_THREAD_SAFE_FUNCTIONS ) >= 0 ) { return ::readdir_r( dirp, entry, result ); } # endif

Seems like _POSIX_THREAD_SAFE_FUNCTIONS but doesn't expand to anything.

That's a common problem with the POSIX feature test macros, the workaround is to use : (_POSIX_THREAD_SAFE_FUNCTIONS+0 >= 0) John.
