I am going to create an application who will find similarity from different subjects..
i am trying to compile the vosm library under mac osx.. but after run cmake and generate makefiles i got the following error when try to compile the library.

/Users/paco/Documents/sviluppo/opencv/vosm/vosm-0.3.2/modules/utils/src/VO_ScanFilesInDir.cpp: In static member function ‘static std::vector<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::allocator<std::basic_string<char, std::char_traits<char>, std::allocator<char> > > > VO_IO::ScanNSortAnnotationInDirectory(const std::string&)’:
/Users/paco/Documents/sviluppo/opencv/vosm/vosm-0.3.2/modules/utils/src/VO_ScanFilesInDir.cpp:119: error: invalid conversion from ‘bool (*)(const std::string&)’ to ‘void*’

Any suggestions?
