i am working with an iOS application in which i have to use Google Drive API and Picasa Api in my application. Google Drive Library libGTLTouchStaticLib.a and picasa library libGDataTouchStaticLib.a. when i used both in my application i get the 204 duplicates symbols in my application.

This is the error: 

duplicate symbol _OBJC_IVAR_$_GTMHTTPFetcher.request_ in:

/Users/bettermac9/Library/Developer/Xcode/DerivedData/PicBackMan-bkstztcwwtsutvgoumkwpscfvaiv/Build/Products/Debug-iphonesimulator/libGTLTouchStaticLib.a(GTMHTTPFetcher.o)

/Users/bettermac9/Desktop/copy latest/PicBackMan 3/libGDataTouchStaticLib.a(GTMHTTPFetcher.o)

Please tell me that how can i remove this error and run my application without any duplicate symbol.

  • i found the answer : if you remove -objc_all-load from the other linker flags it works well. – Roshi Aug 04 '14 at 08:57
