升级xcode10.0编译报错

问题：

Multiple commands produce '/Users/jiaxiaoyan/Library/Developer/Xcode/DerivedData/LJShell-emaksjqtieseunfuiotagpjkluwp/Build/Products/Debug-iphonesimulator/Lianjia_Beike_SecondHand_Private/Lianjia_HomeLink_House_Private.bundle/Info.plist':

1) Target 'Lianjia_Beike_SecondHand_Private-Lianjia_HomeLink_House_Private' has copy command from '/Users/jiaxiaoyan/Desktop/LJworkspace/repoWorkSpaceRootPath/mobile_ios/lianjia_ios_platc/Lianjia_Beike_SecondHand/Lianjia_Beike_SecondHand/Lianjia_Beike_SecondHand/Private/HousePrivate/LJSecondHandHouseComponent/HouseVideo/AliyunVodPlayerSDK.framework/Info.plist' to '/Users/jiaxiaoyan/Library/Developer/Xcode/DerivedData/LJShell-emaksjqtieseunfuiotagpjkluwp/Build/Products/Debug-iphonesimulator/Lianjia_Beike_SecondHand_Private/Lianjia_HomeLink_House_Private.bundle/Info.plist'

2) Target 'Lianjia_Beike_SecondHand_Private-Lianjia_HomeLink_House_Private' has process command with input '/Users/jiaxiaoyan/Desktop/LJworkspace/repoWorkSpaceRootPath/mobile_ios/lianjia_ios_platc/lianjia_ios_platc/Pods/Target Support Files/Lianjia_Beike_SecondHand_Private/ResourceBundle-Lianjia_HomeLink_House_Private-Info.plist'

由于重复文件是其他部门有依赖，所以修改了xcode的配置暂时解决了编译报错的问题。

xcode--file--Workspace Settings--Build System--legacy Build System

再次编译，提示，遇到问题

library not found for -l"stdc++.6.0.9"

 原因：Xcode10取消了6.0.9的支持，但是在xcode9上面可以找到

解决办法：

（打开Build Phases--Link Binary With Libraries，删除6.0.9依赖   添加Libc++.tdb，这些都没用）

如果依赖c++6.0.9的SDK是第三方SDK，需要联系第三方，等待第三方更新

如果是自己的文件引用了c++，请替换对c++库的使用，重新编译
