C++ Projects that Use LabWindows™/CVI™ Functions? Primary Software: LabWindows/CVI Development Systems>>LabWindows/CVI Base Package Primary Software Version: 2009 SP1 Primary Software Fixed Version: N/A Secondary Software: N/A Problem: I am trying to use LabWindows/CVI functions in my Visual Studio C++ project, but when I try to compile my code I receive linking errors similar to the following:error LNK2019: unresolved external symbol How can I resolve this error? Solution: In order to compile LabWindows/CVI functions in a Visual Studio C++ program, you first have to build the functions into a dynamic-link library (DLL) with an import library, and then link the import library (.lib) to your C++ project. To build the functions into a DLL and resolve the link errors, complete the following steps: Note:If the functions you are trying to use are already bundled into a DLL with an import library, you can skip steps 1 through 6. If the instrument driver that includes the functions is not already loaded into LabWindows/CVI, you will need to load it by going to Instrument»Load. In the dialog box that opens, navigate to the .fp file of interest and click Load. Open the Function Tree Editor by going to File»Open»Function Tree (*.fp).In the dialog box that opens, navigate to the .fp file of interest and click Load. Create a DLL project by going to Options»Create DLL Project. Specify a path and name for your project and click Save.A message will pop up asking you if you want to load the DLL project now, similar to the dialog below. Click Yes. Before building the DLL, you will need to configure some of the build settings. First set the build target type by going toBuild»Target Typeand making sure there is a checkmark next to Dynamic Link Library. Also set the project to release mode by going to Build»Configurationand ensuring there is a checkmark next to Release. Configure the target settings by going to Build»Target Settings. Change the Run-time supportoption to Full run-time engine, as shown in the image below: Also change the type library settings by clicking Type Library and unchecking Add type library resource to DLL, as shown in the images below. If you do not uncheck this option, you may run into a type definition error when attempting to build, similar to the following:Definitions for these types could not be found. Then click OK to exit out of both windows. Build the DLL. In LabWindows/CVI 2012 or earlier, selectBuild»Create Release Dynamic Link Library. In LabWindows/CVI 2013, select Build»Build. This will create a dynamic-link library (.dll) and an import library
