First of all it is difficult to identify errors esp you don't have the source code. However the stockoverflow discussion was good enough to point out the general problems.
ld: duplicate symbol _EstimateBas64EncodedDataSize in /Users/pratgupta/ Desktop/Settinglinkedin/10_mar_butterfli/LinkedInClientLibrary/build/ Debug-iphonesimulator/libLinkedInClientLibrary.a(Base64Transcoder.o) and /Users/pratgupta/Desktop/Settinglinkedin/10_mar_butterfli/Twitter +OAuth/Libraries & Headers/libOAuth.a(Base64Transcoder.o) Problem is: duplicate symbol It occurs on _EstimateBas64EncodedDataSize from LinkedinClientLibrary in libLinkedInClientLibrary.a(Base64Transcoder.o) and Twitter+OAuth in libOAuth.a(Base64Transcoder.o). Note: LinkedIn library and Ben Gottlieb's Twitter client include the same OAuthConsumer code. It is duplicated. libLinkedInClientLibrary and libOAuth both symbolicate the same method '_EstimateBas64EncodedDataSize'. Check your #imports. Just do a search within your Xcode project on _EstimateBas64EncodedDataSize. Find out where the duplicated methods. Determine which one you should remove.
