llvm dev - Dec 2018 - Kaleidoscope Chapter 8 linker command failed with exit code 1143

Hi,

I am new to LLVM and wanted to experiment with the Kaleidoscope example. My
PC is a Windows 64 bit system. I managed to build LLVM from source with
CMake. I managed to build the examples of Kaleidoscope with Visual Studio
15 2017 from the .vcxproj file. The built toy.exe from chapter 8 runs well
from the command line and I could enter the function definition for average
as in the tutorial. toy wrote output.o to D:\llvm.bld\Debug\bin.

However, when I would like to compile and link the main.cpp as given in the
tutorial I get:
clang++.exe: error: linker command failed with exit code 1143 (use -v to
see invocation).

The full verbose output is copied below. How do you compile and link
main.cpp and output.o on a Windows 64 bit PC?

Greetings,

Ad Huikeshoven
