Unity 3D iOS游戲構建失敗Xcode 8.32：“clang錯誤鏈接器命令失敗，退出代碼為1”

Question

細節：

• Unity：5.6.0f3
• Xcode：版本8.3.2（8E2002）
• 構建：虛擬現實iOS手機游戲（我在構建設置中唯一改變的是從伽瑪到線性的顏色配置文件......）

我是Unity 3D的初學者，想要通過Xcode在iOS上測試構建我的游戲。 但是，我已經嘗試了很多次，並且這個錯誤不斷出現。

Apple Mach-O鏈接器（ld）錯誤組clang：錯誤：鏈接器命令失敗，退出代碼為1（使用-v查看調用）

ld：1446個用於體系結構armv7的重復符號

Answer 1

感謝Phillip Mills尋找解決方案的鏈接！

引自網站，

1. 將GVROverlayView.h文件從Pods / Headers / Public / GVRSDK文件夾復制到頂級Classes文件夾。打開主.xcodeproj文件。
2. 從左窗格中刪除libPods-Unity-iPhone.a文件。
3. 在“構建設置”下，雙擊“其他鏈接器標志”中的第一行。 截圖照片
4. 刪除$（繼承）行。
5. 建立項目。
6. 利潤。

Answer 2

我還在上面鏈接的https://github.com/googlevr/gvr-ios-sdk/issues/234上添加了評論。 我會在這里復制....

上述問題實際上是一個與＃259不同的問題，因為升級了GoogleVR統一包，而沒有刪除對舊libgvrunity.a的所有引用。

如果libGVRSDK.a和libgvrunity.a正在創建大量沖突符號，則需要重新導入GoogleVRForUnity.unitypackage。 但首先你需要瀏覽你的Assets / Plugins目錄並刪除對GVR的任何引用，包括libgvrunity.a。 Unity的包管理器不會從以前導入的包中刪除與包更新沖突的文件。
