Boost 1.45 does not build on AIX using the latest compiler. v11.1 Error's of the following are shown: vacpp.compile.c++ tmpBuildDir/boost/bin.v2/libs/filesystem/build/vacpp/debug/link-static/threading-multi/v3/src/operations.o "./boost/filesystem/v3/path.hpp", line 482.7: 1540-0716 (S) The template argument "boost::iterator" does not match the template parameter "class Derived". It appears that this has been broken for quite a while. At least since boost 1.44 Are the authors of file system aware of this issue and are there any plans to get this fixed ? Does any one know of any work around ? Any help appreciated. Best regards, Ta, Avi
