I'm using Visual Studio 2013. I make the solution name MyProjectTest This is the structure of my test solution: -function.h #ifndef MY_FUNCTION_H #define MY_FUNCTION_H int multiple(int x, int y); #endif -function.cpp #include "function.h" int multiple(int x, int y){ return x*y; } -main.cpp #include

is the simple program and it run ok without error. I read in the internet and interested in the unit test, so I creat the test project: File > New > Project... > Installed > Templates > Visual C++ > Test > Native Unit Test Project > Name: UnitTest1 Solution: Add to solution then the location auto switch to the path of current opening solution This is the folder structure of the solution: I edit only file unittest1.cpp: #include "stdafx.h" #include "CppUnitTest.h" #include "../MyProjectTest/function.h" using namespace Microsoft::VisualStudio::CppUnitTestFramework; namespace UnitTest1 { TEST_CLASS(UnitTest1) { public: TEST_METHOD(TestEqual) { Assert::AreEqual(multiple(2, 3), 6); // TODO: Your test code here } }; } But I get error LNK2019: unresolved external symbol I know that it is missing the implement of function multiple. I try to delete file function.cpp and replace the declare with the defination, and it run. But It is not recommend to write both declare and defination in the same file. How can i fix this error without do that. Should I replace with #include "../MyProjectTest/function.cpp" in file unittest.cpp? (I'm not good at english very much. Thanks) c++ testing error-handling lnk2019 share|improve this question edited Nov 10 '13 at 5:00 asked Nov 10 '13 at 4:47 user2447581 69321017 possible duplicate of What is an undefined reference/unresolved external symbol error and how do I fix it? –WhozCraig Nov 10 '13 at 5:02

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 http://digital.ni.com/public.nsf/allkb/36F561F57095CADB86257CC4006C275B 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) error lnk2019 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 unresolved external symbol 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 attemp
