我使用LLVMGCC4.2编译器，但出于某种原因，我想使用苹果LLVM编译器。我使用一些静态链接的提升库。

我的代码部分在这里：

#include <boost/program_options/detail/config_file.hpp>

std::set<std::string> options;
std::map<std::string, std::string> parameters;
options.insert("*");

for (config_file_iterator i(config, options), e ; i != e; ++i) 
    parameters[i->string_key] = i->value[0];

当我将Xcode 4.5.1中的编译器更改为AppleLLVM4.1时，它会给我这个错误：

    In file included from A.cpp:16:
    boost_1_46_1/boost/program_options/detail/config_file.hpp:163:17: error: 
    call to function 'to_internal' that is neither visible in the template 
    definition nor found by argument-dependent lookup
        s = to_internal(in);
            ^
    A.cpp:82:39: note: in instantiation of member function

    'to_internal' should be declared prior to the call site or 
    in namespace '__gnu_cxx'

        BOOST_PROGRAM_OPTIONS_DECL std::string to_internal(const std::string&);

有人知道解决办法是什么吗？
