Xcode中静态链接id3lib的问题

我想将id3lib静态链接到我的XCode项目。我在其他线程中发现了一些答案，建议将作为链接器标志添加到.a文件的完整路径。这种方法有效，但会产生大量的错误：Xcode中静态链接id3lib的问题

     std::__1::basic_string<unsigned char, std::__1::char_traits<unsigned char>,

依此类推。再次，谷歌搜索表明，这个问题可能是标准库的选择。因此，我尝试将C++标准库字段从“编译器默认”字段切换到“libstdC++”（并且仍然收到大量错误）或“libC++” - 并且我得到的错误更少，即：

Undefined symbols for architecture x86_64:

    "_iconv", referenced from:

ld: symbol(s) not found for architecture x86_64 
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我不知道如何解决这个问题。如果我将链接器标志库的完整路径移除，一切似乎都奏效，但该库是动态链接的（这对我不起作用）。我在Mac OS X 10.10上; id3lib通过自制软件安装（手动安装测试导致类似的结果）。

有没有人有线索？

感谢，丹尼尔

转到项目设置链接二进制与图书馆和与系统库链接您的项目libz进行（_compress，_uncompress）和libiconv的（_iconv，_iconv_close，_iconv_open）。
