g++-4.2 failed with exit code 1

can anyone help with my final hurdle? I can see the error seems to be for the duplicate symbol but I don’t know how to remove and rebuild.

Command /Developer/usr/bin/llvm-g+±4.2 failed with exit code 1

ld: duplicate symbol _main in /Users/suki/Desktop/of_preRelease_v0062_osxSL_FAT/apps/examples/example copy/build/ofxKinect.build/Debug/ofxKinect.build/Objects-normal/i386/main-EB2D0D723288BE79.o and /Users/suki/Desktop/of_preRelease_v0062_osxSL_FAT/apps/examples/example copy/build/ofxKinect.build/Debug/ofxKinect.build/Objects-normal/i386/main-82227D70F1DD098B.o for architecture i386


problem resolved by deleting duplicate files in target/compile sources
