升級xcode10.0後，編譯原有正常工程遇到的坑
阿新 • • 發佈：2018-12-10
一大早上看到可以升級xcode10，心情美美噠。然而升級完，開始編譯原有正常工程，卻報錯了。
提示有重複的檔案。
問題1：
- Multiple commands produce '/Users/wmh/Library/Developer/Xcode/DerivedData/GS_Mobile-dsuqtvptcdfuyyfqjtnevxwiayup/Build/Products/Debug-iphonesimulator/GS_Mobile.app/Info.plist':
- 1) Target 'GS_Mobile' (project 'GS_Mobile') has copy command from '/Users/wmh/Project/GSYD_XinJiang/GS_Mobile/Tools/FSCalendar/Info.plist' to '/Users/wmh/Library/Developer/Xcode/DerivedData/GS_Mobile-dsuqtvptcdfuyyfqjtnevxwiayup/Build/Products/Debug-iphonesimulator/GS_Mobile.app/Info.plist'
- 2) Target 'GS_Mobile' (project 'GS_Mobile') has copy command from '/Users/wmh/Project/GSYD_XinJiang/GS_Mobile/Tools/MJExtension/Info.plist' to '/Users/wmh/Library/Developer/Xcode/DerivedData/GS_Mobile-dsuqtvptcdfuyyfqjtnevxwiayup/Build/Products/Debug-iphonesimulator/GS_Mobile.app/Info.plist'
- 3) Target 'GS_Mobile' (project 'GS_Mobile') has process command with output '/Users/wmh/Library/Developer/Xcode/DerivedData/GS_Mobile-dsuqtvptcdfuyyfqjtnevxwiayup/Build/Products/Debug-iphonesimulator/GS_Mobile.app/Info.plist'
問題2
- Multiple commands produce '/Users/wmh/Library/Developer/Xcode/DerivedData/GS_Mobile-dsuqtvptcdfuyyfqjtnevxwiayup/Build/Products/Debug-iphonesimulator/GS_Mobile.app/jquery-1.9.1.min.js':
- 1) Target 'GS_Mobile' (project 'GS_Mobile') has copy command from '/Users/wmh/Project/GSYD_XinJiang/GS_Mobile/Class/Apply/mailhelp/jquery-1.9.1.min.js' to '/Users/wmh/Library/Developer/Xcode/DerivedData/GS_Mobile-dsuqtvptcdfuyyfqjtnevxwiayup/Build/Products/Debug-iphonesimulator/GS_Mobile.app/jquery-1.9.1.min.js'
- 2) Target 'GS_Mobile' (project 'GS_Mobile') has copy command from '/Users/wmh/Project/GSYD_XinJiang/GS_Mobile/Tools/library/help1/jquery-1.9.1.min.js' to '/Users/wmh/Library/Developer/Xcode/DerivedData/GS_Mobile-dsuqtvptcdfuyyfqjtnevxwiayup/Build/Products/Debug-iphonesimulator/GS_Mobile.app/jquery-1.9.1.min.js'
報錯原因：重複，由於重複檔案是其他部門有依賴，所以有兩種解決方案
方案1--> 修改了xcode的配置暫時解決了編譯報錯的問題。
xcode--file--project settings--Build System--legacy Build System
再次編譯，提示，遇到問題
library not found for -l"stdc++.6.0.9"
原因：Xcode10取消了6.0.9的支援，但是在xcode9上面可以找到，
解決辦法：
（開啟Build Phases--Link Binary With Libraries，刪除6.0.9依賴 ）
如果依賴c++6.0.9的SDK是第三方SDK，需要聯絡第三方，等待第三方更新
如果是自己的檔案引用了c++，請替換對c++庫的使用，重新編譯
方案2---> 1，選擇開啟所在的專案Target ----> Build Phases ---->Copy Bundle Resources ；2，刪除報錯的那些檔案，
