The VS Generator build finished now, once again with similar errors, but this time I saved the output to a log file as you explained:
Full build.log
As I said in my last post, I am right now a little bit confused as of what the next steps are, because I feel like we are treating several different problems / methods at the same time. I would be very thankful, if you could elaborate a little bit on what I should do next.
Anyways thank you very much for your support, I appreciate it a lot, and I hope that this log can help you helping me
