Unity 3D iOS游戏构建失败Xcode 8.32：“clang错误链接器命令失败，退出代码为1”

Question

细节：

• Unity：5.6.0f3
• Xcode：版本8.3.2（8E2002）
• 构建：虚拟现实iOS手机游戏（我在构建设置中唯一改变的是从伽玛到线性的颜色配置文件......）

我是Unity 3D的初学者，想要通过Xcode在iOS上测试构建我的游戏。 但是，我已经尝试了很多次，并且这个错误不断出现。

Apple Mach-O链接器（ld）错误组clang：错误：链接器命令失败，退出代码为1（使用-v查看调用）

ld：1446个用于体系结构armv7的重复符号

Answer 1

感谢Phillip Mills寻找解决方案的链接！

引自网站，

1. 将GVROverlayView.h文件从Pods / Headers / Public / GVRSDK文件夹复制到顶级Classes文件夹。打开主.xcodeproj文件。
2. 从左窗格中删除libPods-Unity-iPhone.a文件。
3. 在“构建设置”下，双击“其他链接器标志”中的第一行。 截图照片
4. 删除$（继承）行。
5. 建立项目。
6. 利润。

Answer 2

我还在上面链接的https://github.com/googlevr/gvr-ios-sdk/issues/234上添加了评论。 我会在这里复制....

上述问题实际上是一个与＃259不同的问题，因为升级了GoogleVR统一包，而没有删除对旧libgvrunity.a的所有引用。

如果libGVRSDK.a和libgvrunity.a正在创建大量冲突符号，则需要重新导入GoogleVRForUnity.unitypackage。 但首先你需要浏览你的Assets / Plugins目录并删除对GVR的任何引用，包括libgvrunity.a。 Unity的包管理器不会从以前导入的包中删除与包更新冲突的文件。
