To prevent name mangling in my DLL, I syntax error have used the EXPORT definition defined below: #ifndef EXPORT #define EXPORT extern "C" __declspec(dllexport) #endif EXPORT int _stdcall SteadyFor(double Par[], double Inlet[], double Outlet[]); To get this code to compile, I had to go into the project's Properties and set the C/C++ Calling Convention to __stdcall (/Gz) and set Compile As to Compile as C++ Code (/TP). This worked in Debug mode, but Release mode is throwing error C2059: syntax error: 'string' on all of my EXPORT functions - even though c2059 syntax error I have configured the Release mode settings to be the same as the Debug settings. How do I get Release Mode to compile? Regards, ~Joe (Developing under Visual Studio 2008 Professional) EDIT: A lot of comments about my #define, which does not appear to be causing any problems. To eliminate the confusion, my header file has been rewritten as follows: #ifndef coilmodel_h #define coilmodel_h extern "C" __declspec(dllexport) int _stdcall steadyFor(double Par[], double Inlet[], double Outlet[], char* FileIn, char* FileOut); #endif That is all of it. The error is: Description error C2059: syntax error: 'string' File coilmodel.h Line 4 Again, this error only appears in Release mode, not Debug mode. Project is a C++ Win32 DLL application. c++ dll extern share|improve this question edited Jun 22 '10 at 15:55 asked Jun 22 '10 at 15:22 jp2code 12.8k1991175 I think the code you posted is not relevant to the problem. Can you tell us which line chokes as well as post the code for that line. From the code you posted it looks like you do not have EXPORT defined in Release mode. –Romain Hippeau Jun 22 '10 at 15:26 See my "Edit" section above.

Calling C++ functions in C code is problematic for at least two reasons: C does not recognize the overloading of function names which will be determined during the compiler's parsing phase. If you have overloaded functions defined in test.h, this will lead to compile errors. C++ mangles the name of functions along with their argument types with a vendor specific algorithm. This can make linking code compiled with different compilers difficult to impossible without resorting to assembly language shims. The description provided above does not lead me to believe that this is what you are experiencing.Searching for "C2059" in Google reveals the following: http://msdn.microsoft.com/en-us/libr...cf(VS.80).aspx You should study this information as well.
