升級Xcode 10 後報錯問題記錄([CP] Copy Pods Resources)&& library not found for -libstdc++.6.0.9

一、升級Xcode到Version 10.0 (10A255)後,運行已有項目,報以下錯誤:c++

error: Multiple commands produce '/Users/galahad/Library/Developer/Xcode/DerivedData/yoowei-drnrntneloepunakcqbcdycudqeh/Build/Products/Debug-iphoneos/yoowei.app':xcode

1) Target 'yoowei' has create directory command with output '/Users/galahad/Library/Developer/Xcode/DerivedData/yoowei-drnrntneloepunakcqbcdycudqeh/Build/Products/Debug-iphoneos/yoowei.app'bash

2) That command depends on command in Target 'yoowei': script phase 「[CP] Copy Pods Resources」app

 

緣由:Xcode 10 默認使用的build system是New build system,與Xcode9不一樣致使。iphone

解決:2種方法ui

1)第一種方法 不修改build system spa

根據error 日誌,script phase 「[CP] Copy Pods Resources」,並且與output有關,應該是使用了cocoapods致使的,嘗試刪除該項目target-Copy Pods Resources-Output Files,成功解決問題。選中項目target -> Build phase -> Copy Pods Resources -> Output Files -> 移除${TARGET_BUILD_DIR}/${UNLOCALIZED_RESOURCES_FOLDER_PATH}  而後從新編譯,OK 。日誌

用這種方式緊接着會有下面的錯誤:

error: Cycle in dependencies between targets 'yooweiExtension' and 'yoowei'; building could produce unreliable results.

Cycle path: yooweiExtension → yoowei → yooweiExtensioncode

Cycle details:orm

→ Target 'yooweiExtension': CodeSign /Users/galahad/Library/Developer/Xcode/DerivedData/yoowei-drnrntneloepunakcqbcdycudqeh/Build/Products/Debug-iphoneos/yooweiExtension.appex

○ Target 'yooweiExtension': ProcessProductPackaging  /Users/galahad/Library/Developer/Xcode/DerivedData/yoowei-drnrntneloepunakcqbcdycudqeh/Build/Intermediates.noindex/yoowei.build/Debug-iphoneos/yooweiExtension.build/yooweiExtension.appex.xcent

○ Target 'yooweiExtension' has target dependency on Target 'yoowei'

→ Target 'yoowei' has target dependency on Target 'yooweiExtension'

○ That command depends on command in Target 'yooweiExtension': script phase 「[CP] Check Pods Manifest.lock」

對應的解決方案:選中項目target -> Build phase -> Target Dependencies  去掉相互的依賴便可

 

2)第二種方法 修改build system 
在Xcode菜單欄 -> File -> Workspace Setting,將build system修改成legacy build system,而後clean後編譯。

二、典型問題

ld: library not found for -lstdc++.6.0.9

clang: error: linker command failed with exit code 1 (use -v to see invocation)

解決方案:(我通常升級xcode 以前都會將lib 給備份一份。具體路徑是:/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib )

一、提早在xcode 9中 根據路徑   /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib 找到 libstdc++.6.0.9.tbd  備份

二、複製剛纔的libstdc++.6.0.9.tbd 文件,手動添加到 升級後的xcode 10  /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib 文件夾中,運行便可。

須要的話,能夠找我要。注意分真機和模擬器環境:

1.真機環境:/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib/
2.模擬器環境:/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/lib/ 

20190313遇到一種狀況:編譯報錯     library not found for -l"stdc++.6.0.9" 

比較奇怪就是,我已經按照上面將libstdc++.6.0.9.tbd 手動添加過了。可是爲何還會報錯呢?

解決辦法:

打開Build Phases--Link Binary With Libraries,刪除6.0.9依賴   添加Libc++.tdb 便可。

若是依賴c++6.0.9的SDK是第三方SDK等待第三方更新解決。
