I would recommend you check the symbols contained in the .lib file you're trying to link to with the following command: dumpbin.exe -headers libsndfile.lib. Issue that command in the "Visual Studio Command Prompt" and take a look at the resulting output. Check to make sure the exact symbols you're trying to link

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: http://digital.ni.com/public.nsf/allkb/36F561F57095CADB86257CC4006C275B 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 https://github.com/JanBoonen/TwsApiCpp/issues/3 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 visual studio 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 visual studio error 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-t

TwsApiCpp version 9.71. When we open the TwsApi.sln solution there is a "One way upgrade" that produces the following warnings (two examples - there are a total of 12): ..\Test_win32\Test.vcproj: Warning: The project file is being backed up to a relative path that differs from the original solution relative path. The difference in folder hierarchy may create problems in opening or building the backed up solution and project. ..\Test_win32\Test.vcproj: MSB8012: $(TargetPath) ('C:\Jts\TwsApiCpp\TwsApiC++\Test_win32.\Debug\Test.exe') does not match the Librarian's OutputFile property value '.\Debug\Test.exe' ('C:\Jts\TwsApiCpp\TwsApiC++_win32\Debug\Test.exe') in project configuration 'Debug|Win32'. This may cause your project to build incorrectly. To correct this, please make sure that $(TargetPath) property value matches the value specified in %(Lib.OutputFile). Issue: When building the "Test" project in Visual Studio 2013 (and possibly in other versions of VS), the following error appears on linking: error LNK2019: unresolved external symbol "public: static class EClientL0 * __cdecl EClientL0::New(class EWrapperL0 *)" (?New@EClientL0@@SAPAV1@PAVEWrapperL0@@@Z) referenced in function _main C:\Jts\TwsApiCpp\TwsApiC++\Test_win32\Empty.obj Test The solution appears to be: 1. Open up the Test Project Properties and then navigate to Configuration Properties -> Linker -> General. Add the full path the Api folder in the Additional Library Directories. For exmaple: C:\Jts\TwsApiCpp\TwsApiC++\Api Open up the Test Project Properties and then navigate to Configuration Properties -> Linker -> Input. Add the TwsApi.lib file to the list that appears in Additional Dependencies. I suspect it is just a matter of references to the Include and lib folders cha
