Hi Originally the application was written in CVI 6.0. I have now created a completly new project and workspace and added all the files. The compilation works fine. But the error message I get when linking (build) is " error: Input file is not a valid archive: 'c:\Projects\........\bin\i7000.lib'. " With another library I get the same problem: "uart.lib" The other lib-files just work fine. I saw in an old post a solution: to just recreate the project which I did. But it didn't work in my case. Any help? Cheers Andreas

Hi Andreas, This linking issue you are seeing can usually be fixed by building a new .lib file. You don't need the source code to do so, just the associated .h header file. If you open the .h file that goes with your DLL in CVI, you can select Options > Generate DLL Import Library... to create a new .lib file that should work with the CVI 2013 linker to get rid of this error.

Hi Andreas, I've tried to build a simple project calling one function from each of the libraries you provided: Get_Uart_Version();FloatToHex(12.34); The project was building successfully, there was no linker error. I've tried it both with CVI 2013 and CVI 2013 SP2. Could you try and see if such a simple project still gives the same link error for you? If not, it is possible that the problem is not only a library format issue. You would have to try and simplify the project until you find the portion of code that triggers the linker error. As an alternative, you could send us your project and we can try to isolate the problem. Best regards,Alpar
