Linking problems with Ice 3.7.3

Hi,

sorry to post such a semi-Ice-specific question here. I've been searching for two days now without any cure so I thought I'd try my luck and ask.

I am migrating a fairly old C++ application from Ice 3.4.1. I first stepped to Ice 3.5 (custom built Ice with VC142/ Visual Studio 2019) in order to update the AMI calls which worked out pretty well.
Then I moved on to Ice 3.7.3 using Ice Builder and nuget packages. Slicing and building worked fine but on linking I receive odd errors that I have never seen before:

This happens regardless if I add ice37d.lib et al into the additional linking dependencies or not. Do you have any idea why this happens and how I can solve this?

Thanks a lot in advance for your help!

Cheers,

Stephan

There is no __copyFrom in 3.7 seems you still have some object files from your 3.5 build

My first boss said: "the longer you search for a bug, the more obvious it is."
Thanks a lot, deleting all old .objs did the trick!
