Solved Errors building math.framework

Hi,

I have set up a new Windows PC, installed Visual Studio 2019 and Cinema 4D R23.110 and and the project tool. Generated the project files for frameworks and plugins. Now I am trying to build the example plugins.

However, any build fails because of errors in math.framework:

In deed, the file blend_animation.cpp in math.framework mentions a class BlendAnimationRef, but that class is only forward-declared in blend_animation.h, but doesn't seem to be implemented anywhere.

Why? And how can I fix it?

One thing to add: In S24 it just works. Strange. The *blend_animation*.hxx files look identical to me.

Oh, wow. Thank you!
I didn't know about this problem, for some reason it never occurred on my VirtualBox Windows I used for building until recently.

Will read and fix, thanks again!

Cheers,
Frank

Oh yes, it works. Therefore, the topic is solved
