Hello! Would you mind sharing some details about your setup? What OS and compiler are you using?

It seems like you’re running Windows. What command prompt are you using?

Also, I might add that the WIndows version of Carp is sadly extremely undertested. We appreciate you trying it out there, but you might run into trouble getting everything to work properly at this time.

Try installing LLVM and use clang-cl.exe for compilation.
