There are a fair number of related questions out there already, but I'm just not getting this resolved. I'm building an application that includes two separate static libraries: RestKit and another that's on NDA. When I build, I'm getting a Apple Mach-O linker error as follows:
duplicate symbol _NewBase64Decode
in /Users/geraldwburke/Desktop/iOS Programming/MyApp/someLib.a(NSData+Base64.o)
and /Users/geraldwburke/Library/Developer/Xcode/DerivedData/MyAppddlwzdeskfwaxyargomvfhurvxzi/Build/Products/Debug-iphoneos/libRestKit.a(NSData+Base64.o)
for architecture armv7
Now, I've seen some potential fixes out there. This article seemed promising. I also tried to add a build rule using the script from this blog entry. I've tried adding and removing -ObjC, -all_load, and -force_load linker flags. No matter what I have tried, I still get that same error. Does anyone have any idea how to fix this?
BTW I will delete my identical post. Posted it on the wrong acct.
The easiest solution is to modify the source code of one of those libraries to not define NewBase64Decode. RestKit is open source; I don't know if you have the source to your secret NDA library.
