I am trying to build Boost.Filesystem (release 1.34) on a GNU/Linux x86_64 system with Portland Group compilers (there is no official support for this compiler). Everything else seems to work nice and dandy, except this single error with compiling operations.cpp: "operations.cpp", line 1247: error: a value of type "dirent64 *" cannot be assigned to an entity of type "dirent *" if ( (p = ::readdir( dirp )) == 0 ) ^ If I comment out the following defines in operations.cpp:22 and operations.cpp:25 #define _FILE_OFFSET_BITS 64 #define __USE_FILE_OFFSET64 the error goes away. But I doubt this is the correct way to fix this. Any ideas? thanks Levent -- Server Levent Yilmaz Mechanical Engineering University of Pittsburgh
