Join them; it only takes a minute: Sign up c++: definition of dllimport function not allowed, building with visual studio 2010 up vote 8 down vote favorite 2 I'm using visual studio 2010 to build a .dll. I wrote up a trial as: // trialDLL.h #ifndef TRIALDLL_H_ #define TRIALDLL_H_ // ... MyMathFuncs class definition http://stackoverflow.com/questions/17239506/c-definition-of-dllimport-function-not-allowed-building-with-visual-studio-2 omitted #ifdef __cplusplus extern "C"{ #endif #ifdef TRIALDLL_EXPORT #define TRIALDLL_API __declspec(dllexport) #else #define TRIALDLL_API __declspec(dllimport) #endif TRIALDLL_API MyMathFuncs* __stdcall new_MyMathFuncs(double offset); TRIALDLL_API void __stdcall del_MyMathFuncs(MyMathFuncs *myMath); TRIALDLL_API double __stdcall MyAdd(MyMathFuncs* myMath, double a, double b); // some other similar stuff #ifdef __cplusplus } #endif #endif And the triallDLL.cpp file: // trialDLL.cpp #include "trialDLL.h" TRIALDLL_API MyMathFuncs* __stdcall new_MyMathFuncs(double offset) { return new MyMathFuncs(offset); } TRIALDLL_API void __stdcall del_MyMathFuncs(MyMathFuncs *myMath) { delete myMath; } TRIALDLL_API double __stdcall MyAdd(MyMathFuncs *myMath, double a, double b) { return myMath->Add(a, b); } // ... some other definitions With these two files in the project, I added a property sheet to the project through visual studio 2010 property manager and added TRIALDLL_EXPORT to user macros. After all these, the nice Intellisense gives me error for each function defined in the .cpp file and complains "error: a function declared 'dllimport' may not be defined". So it appears that Intellisense doesn't find TRIALDLL_EXPORT defined. I thought it might make a difference if I actually build the project, but t

To test this, right-click on RLIB_EXPORTS and select "Go to definition of dllimport definition". If RLIB_EXPORTS is undefined, open Project - Settings - C++, and add RLIB_EXPORTS Go to Solution 18 Comments LVL 86 Overall: Level 86 C++ 72 Message Assisted Solution by:jkr2004-02-04 >>does anyone knows how this can be solved ? Move the '__declspec(dllimport)' to the declaration, not the definition. According to the error message, you are currently trying to compile sth. like void __declspec(dllimport) Function_1 () { int i = 1 + 1; } 0 Message Author Comment by:André1232004-02-04 this is my code: /////// #include
responsible for array handling. This project is build as DLL. The second project uses that DLL and its implemented classes. At first I had the following problem: I've tried to make the class much more flexible by using templates. At first that does not work, I got a linker error, that means, I have to define template methods in my header file. At this point the methods I used as templates are defined in my header class and the declaration is in my cpp file. I searched for the right solution and on some websites I read, that I have to implement the template method declaration also in my header file. After this steps I got a new error: 1
