Hi everyone, I recently obtained a new Mackbook pro with Os X leopard on it. I installed the latest Boost library using Macports . Yet when I take my previous projects (build on Os X tiger with Xcode 2.5 and Boost -1_34_1) I have problems with the programming_options library. So I created a simple command line project (see main in the end of this mail) to track down the problem and found that Xcode is having problems with strings in the program options. I'm writing Xcode because when I compile the same code from command line using g++ there are no problems at all. So it has to be somewhere in the specifications. I'm pretty sure that I specified where to look for the header files and the libraries. I added the libprogram_options_mt-1_35.dylib as a framework to the Xcode project. The code compiles in Release configuration but when I try to run it I get :
./test -R 1 -L 1 -A 20 -S data.in -O result.txt terminate called after throwing an instance of 'boost::bad_any_cast' what(): boost::bad_any_cast: failed conversion using boost::any_cast Abort trap
The problem arises as soon as the code starts to process the vector<string> arguments. When I then try to compile the samen code in Debug model I get three errors: mkdir /Users/tlenaert/Desktop/test/build/Debug cd /Users/tlenaert/Desktop/test /Developer/usr/bin/g++-4.0 -o /Users/tlenaert/Desktop/test/build/Debug/test -L/Users/tlenaert/Desktop/test/build/Debug -L/opt/local/lib -L/opt/local/lib -F/Users/tlenaert/Desktop/test/build/Debug -filelist /Users/tlenaert/Desktop/test/build/test.build/Debug/test.build/Objects-normal/i386/test.LinkFileList -lboost_program_options-mt-1_35 -arch i386 -mmacosx-version-min=10.5 -isysroot /Developer/SDKs/MacOSX10.5.sdk Undefined symbols: "boost::program_options::value_semantic_codecvt_helper<char>::parse(boost::any&, __gnu_debug_def::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> > > > const&, bool) const", referenced from: vtable for boost::program_options::typed_value<__gnu_debug_def::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> > > >, char>in main.o vtable for boost::program_options::typed_value<int, char>in main.o vtable for boost::program_options::typed_value<double, char>in main.o "boost::program_options::detail::cmdline::cmdline(__gnu_debug_def::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> > > > const&)", referenced from: boost::program_options::basic_command_line_parser<char>::basic_command_line_parser(int, char**)in main.o "boost::program_options::validate(boost::any&, __gnu_debug_def::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> > > > const&, std::basic_string<char, std::char_traits<char>, std::allocator<char> >*, int)", referenced from: void boost::program_options::validate<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, char>(boost::any&, __gnu_debug_def::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> > > > const&, __gnu_debug_def::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> > > >*, int)in main.o ld: symbol(s) not found collect2: ld returned 1 exit status "boost::program_options::value_semantic_codecvt_helper<char>::parse(boost::any&, __gnu_debug_def::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> > > > const&, bool) const", referenced from: vtable for boost::program_options::typed_value<__gnu_debug_def::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> > > >, char>in main.o vtable for boost::program_options::typed_value<int, char>in main.o vtable for boost::program_options::typed_value<double, char>in main.o "boost::program_options::detail::cmdline::cmdline(__gnu_debug_def::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> > > > const&)", referenced from: boost::program_options::basic_command_line_parser<char>::basic_command_line_parser(int, char**)in main.o "boost::program_options::validate(boost::any&, __gnu_debug_def::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> > > > const&, std::basic_string<char, std::char_traits<char>, std::allocator<char> >*, int)", referenced from: void boost::program_options::validate<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, char>(boost::any&, __gnu_debug_def::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> > > > const&, __gnu_debug_def::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> > > >*, int)in main.o ld: symbol(s) not found collect2: ld returned 1 exit status Build failed (3 errors) IS there anyone here who cam across a similar problem or who can help me out?
