<p><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:black">I’ve been trying to get a Clang plugin working for a couple of weeks now on Windows/Visual Studio 2019, and I’m struggling quite a lot. So far, I’ve followed the instructions on
the clang/llvm getting started page, and I’ve got the Clang complier working for C code in visual studio. I then tried to build one of the example plugins provided (such as PrintFunctionNames) using cmake and later make, but I’m having trouble knowing which
file I’m supposed to use and I can’t find much in the way of resources/documentation online for windows stuff. Any and all help would be appreciated.<o:p></o:p></span></p>
