Compiler Warning (level 1) C4399

Error Message

'symbol' : per-process symbol should not be marked with __declspec(dllimport) when compiled with /clr:pure

Data from a native image or an image with native and CLR constructs can not be imported into a pure image. To resolve this warning, compile with /clr (not /clr:pure) or delete __declspec(dllimport).


The following sample generates C4399.

// C4399.cpp
// compile with: /clr:pure /doc /W1 /c
__declspec(dllimport) __declspec(process) extern const int i;   // C4399
