Labview 2009 DLL build error

[Baimei101]

Labview fails to build my DLL and a pop up box appears saying File not found, after clicking OK, the details show:-

Error -2147221480 occurred at Building DLL.
An error occurred compiling the DLL because a function or parameter name is illegal.

If I reset my computer and start labview, the first build is successful with no errors, all further attempts at building a DLL fail with the File not found error.

Does anyone have a suggestion as to the cause of this error?

Thanks.

Hi Baimei101

With labVIEW 2009 then there is a known issue when building DLL s.

Any parameter of type uintptr_t * will cause the LabVIEW application builder to fail when trying to build a shared library, with "Error -2147221480 occurred at Building DLL." 

Workaround: 1. Open C:\Program Files\National Instruments\LabVIEW 2009\cintools\fundtypes.h in a text editor. 
2. Find the line that says #include . 
3. Above that line, add the following lines: 
#ifdef _CVI_ 
#include 
#endif /* _CVI_ */ 
4. Save the file. 
5. Try the build again. 

See the link below for full information on the workaround.

Thanks, already tried that but it didn't fix the problem.

As I said, it will complete the first build, but I can't re-build until I reset the computer and try again.
