Linker Tools Warning LNK4217

  • Article

locally defined symbol 'symbol' imported in function 'function'

__declspec(dllimport) was specified for a symbol even though the symbol is defined locally. Remove the __declspec modifier to resolve this warning.

symbolis the symbol name that's defined within the image. function is the function that is importing the symbol.

This warning will not appear when you compile by using the option /clr.

LNK4217 can also occur if you attempt to link two modules together, when instead you should compile the second module with the import library of the first module.

// LNK4217.cpp
// compile with: /LD
#include "windows.h"
__declspec(dllexport) void func(unsigned short*) {}

And then,

// LNK4217b.cpp
// compile with: /c
#include "windows.h"
__declspec(dllexport) void func(unsigned short*) {}

Attempting to link these two modules will result in LNK4217, compile the second sample with the import library of the first sample to resolve.
