我正在嘗試使用從某個供應商處收到的* .a，* .h文件構建一個小型應用程序。 這是我第一次將外部文件添加到項目中。添加.a文件後架構armv7的未定義符號
我添加了文件，我收到這些錯誤。

到目前爲止，我已經試過：（在其他帖子中提到）
- 我做了肯定的*某文件包括在鏈接的二進制，庫英寸
- 試圖將C++語言方言和C++標準庫更改爲編譯器默認值。
更多信息：
- 的文件是在項目文件夾。
- 我正在使用iPhone 4S v.6.1.3，項目的部署目標是iOS 6.1。
來修復的。您正在鏈接到libmyTrekSDK_armv7.a的.a文件嗎？如果是這樣，它看起來還有另一個它需要它之前（也許Accelerate.framework）...也嘗試鏈接ExternalAccessory.framework – jjv360
