multiple definition of `gImGuiUserEventCallback' #22

Closed traw closed 7 years ago

traw commented 7 years ago

When implementing gImGuiUserEventCallback in SDL2 binding causing linker error.

/imgui-Flix01/imgui.cpp.o:(.bss+0x1f0): multiple definition of `gImGuiUserEventCallback'

my code snippet: ImImplVoidDelegateTakingVoidPtr gImGuiUserEventCallback = HandleUserEvent; It's because of Defination of gImGuiUserEventCallback in imguibindings.cpp, So if I comment it, it works fine.

gImGuiUserEventCallback is already defined in imguibinding.cpp and set to NULL. So you must just assign it: gImGuiUserEventCallback = &HandleUserEvent;
