When I try to create my project, I get the following error.
ld: duplicate .objc_class_name_GLFunView symbol in /Users/gin/Documents/development/GLFun/build/GLFun.build/Debug-iphonesimulator/GLFun.build/Objects-normal/i386/GLFunView-7A51E372BB Users / gb Documents / development / GLFun / build / GLFun.build / Debug-iphonesimulator / GLFun.build / Objects-normal / i386 / GLFunView-7A51E8797CBB3D72.o
What is this error about? How can I track where the error is? Xcode usually allocates code that has problems, but doesn’t show anything for this error? Does this have nothing to do with Interface Builder?
My research shows that this may be caused by the inclusion of something twice, but I do not understand how this is possible, since I do not use any #include statements, I use only #import instructions.
Here is another build result:
