I walked through this tutorial and tried to recreate the example I get this error:
Error 1 error LNK2019: unresolved external symbol __imp__GetXyz@0 referenced in function _main app.obj app
If I download the source from the website and run the project in visual studio it works, but If I even copy the code from the original project in my own visual studio solution it still doesn’t work. I guess it must be some project settings, I don’t know. What do do?
You need to add the XyzLibrary.lib to your Linker settings within project settings.
You can also do it directly in code by using
#pragma comment(lib,"xyzlibrary.lib")if you are using VisualStudio.The reason why it works in the given sample without these 2 approaches is that in the solution file, the dependencies are set from XyzExe to XyzLib, and XyzProject has ‘Link Library Dependencies’ in Linker settings set to true. However, I am not too keen on this approach, as I don’t like to store data important for building inside solution files (for larger projects, developer’s solution files can differ from build system solution files)
