Xcode中靜態鏈接id3lib的問題

我想將id3lib靜態鏈接到我的XCode項目。我在其他線程中發現了一些答案，建議將作爲鏈接器標誌添加到.a文件的完整路徑。這種方法有效，但會產生大量的錯誤：Xcode中靜態鏈接id3lib的問題

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

依此類推。再次，谷歌搜索表明，這個問題可能是標準庫的選擇。因此，我嘗試將C++標準庫字段從「編譯器默認」字段切換到「libstdC++」（並且仍然收到大量錯誤）或「libC++」 - 並且我得到的錯誤更少，即：

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

我不知道如何解決這個問題。如果我將鏈接器標誌庫的完整路徑移除，一切似乎都奏效，但該庫是動態鏈接的（這對我不起作用）。我在Mac OS X 10.10上; id3lib通過自制軟件安裝（手動安裝測試導致類似的結果）。

有沒有人有線索？

感謝，丹尼爾

轉到項目設置鏈接二進制與圖書館和與系統庫鏈接您的項目libz進行（_compress，_uncompress）和libiconv的（_iconv，_iconv_close，_iconv_open）。
