DLI does not compile [message #13934]

I am new to U++ and attempting to write an app that calls a function in a DLL on Windows XP. The dli file looks like this:

FN(long,LabView_wrapper,(int *array1, int array1len, int *array2, int array2len, int *array3, int array3len, int *array4, int array4len, int num1, int num2, int num3, int *num4, int *num5, int *num6))

and the BeatPickerTest.cpp file looks like this:

#include <Core/Core.h>
#define DLLFILENAME "QrsOne_500sps.dll"
#define DLIMODULE   QRSONE_500SPS
#define DLIHEADER   <BeatPickerTest.dli>
#define DLLCALL     LNPUBLIC
#include <Core/dli.h>

CONSOLE_APP_MAIN
{
	
}

and the error says,

Quote:

BeatPickerTest.cpp
C:\MyApps\BeatPickerTest\BeatPickerTest.dli(1) : error C2146: syntax error : missing ')' before identifier 'LabView_wrapper_type'
C:\MyApps\BeatPickerTest\BeatPickerTest.dli(1) : error C2146: syntax error : missing ';' before identifier 'LabView_wrapper_type'

BeatPickerTest: 1 file(s) built in (0:01.64), 1641 msecs / file, duration = 1656 msecs

I would be grateful for any help.

Do you have

using namespace Upp;

before it?

If yes, you can try Build/Preprocess and examine...

If still problem, you can zip the whole package and upload here....

Added using namespace Upp; without fixing the problem. I looked at the preprocessor output but saw nothing obviously wrong. The entire project is attached.

#include <Core/Core.h>

using namespace Upp;

#define DLLFILENAME "QrsOne_500sps.dll"
#define DLIMODULE   QRSONE_500SPS
#define DLIHEADER   <BeatPickerTest/BeatPickerTest.dli>
//#define DLLCALL     LNPUBLIC

#include <Core/dli.h>

CONSOLE_APP_MAIN
{
	
}

(LNPUBLIC is not defined at that point, I guess you will have to add the definition, or maybe it will work without it....)
