Hello Boost Users, I've got problems using Boost.Filesystem v3 under Sun Solaris 10. If I compile this example with -DBOOST_FILESYSTEM_VERSION=3 http://www.boost.org/doc/libs/1_44_0/libs/filesystem/v3/example/tut3.cpp It works like that: bash-3.00# /tmp/bb /etc "/etc" exists, but is neither a regular file nor a directory If I remove this flag (to make it use Filesystem v2) it works as expected. bash-3.00# /opt/csw/gcc4/bin/g++ --version g++ (Blastwave.org Inc.
