Error when building: unresolved external symbol

[rster2002]

I tried rebuilding the application because I wanted to remap some buttons, but I couldn't get it to work. I'm not experienced in building .cpp files, but when I try I get an error log saying that the builder can't resolve external symbols.

The full log after running cl XJoy.cpp:

I might just be doing something wrong, but I thought I would let you decide whether or not it's a bug or just me not knowing how things work.

This happens when it can't find the vigem bus library, and its been so long I honestly forget the details of what needs to be in place to link properly.

You might want to get some help from nefarious, who makes ViGEm https://discordapp.com/invite/QTJpBX5. He would probably be able to tell you exactly what to do based on that error.

Thanks for the response. I'll look there.
