Question

当我尝试将Google VR SDK（'GVRSDK'）添加为Podfile依赖项时，我遇到了React Native的问题，并且它很容易复制。

步骤：

创建一个新的空白React Native项目。使用react-native run-ios运行它以确保其有效。
cd ios
pod init
将pod 'GVRSDK'添加到Podfile，执行pod update
cd ..
react-native run-ios

该项目因以下错误而崩溃：

duplicate symbol __ZN3fLI9FLAGS_novE in:
/foo/ios/Pods/GVRSDK/Libraries/libGVRSDK.a(vlog_is_on.o)

您可以通过删除libGVRSDK.a中的重复符号来解决此问题。 lipo 和 ar 命令用于反汇编多个体系结构中的库文件，并将它们重新归档到另一个文件中。

我按如下方式编写了shell脚本：

pod_post_install.sh

#!/bin/bash

cd ./Pods/GVRSDK/Libraries/
lipo -info libGVRSDK.a

# Divide to each platform
lipo -thin armv7 libGVRSDK.a -output libGVRSDK_armv7
lipo -thin i386 libGVRSDK.a -output libGVRSDK_i386
lipo -thin x86_64 libGVRSDK.a -output libGVRSDK_x86_64
lipo -thin arm64 libGVRSDK.a -output libGVRSDK_arm64

# Delete duplicate file
chmod 777 libGVRSDK_armv7
chmod 777 libGVRSDK_i386
chmod 777 libGVRSDK_x86_64
chmod 777 libGVRSDK_arm64

ar -dv libGVRSDK_armv7 vlog_is_on.o
ar -dv libGVRSDK_i386 vlog_is_on.o
ar -dv libGVRSDK_x86_64 vlog_is_on.o
ar -dv libGVRSDK_arm64 vlog_is_on.o

# rm libGVRSDK.a
lipo -create libGVRSDK_armv7 libGVRSDK_i386 libGVRSDK_x86_64 libGVRSDK_arm64 -output libGVRSDK.a

# Delete media
rm libGVRSDK_armv7
rm libGVRSDK_i386
rm libGVRSDK_x86_64
rm libGVRSDK_arm64

cd ../../../

如果在运行每个pod安装时调用此脚本，则会更有用。

Podfile

post_install do |installer|
    system(". ./pod_post_install.sh")
end

我相信它会有所帮助。

React Native与Google VR SDK不兼容
