Hi,

I haven't tested your exact boost versions and OpenCV-4 yet, but these are linker errors and that's a bit weird. I'd guess it's something with your local configuration. I suggest you play around a bit with the packages and build system and ask on a help page like StackOverflow.com or something like that.

The compile error with CV_BGR2BGRA you can probably easily fix, you just need to find out what the equivalent in OpenCV-4 is. Possibly something similar and namespaced like cv::....

[huihut]

Thanks, I used the vcpkg build system to install boost and opencv, and then compile successfully.

[huihut]

I compiled successfully, but I can't run the fit-model. ( can't find some dll )

When I add these missing dlls, the application does not start properly. ( error 0xc000007b )

Moin,

in case anyone stumbles across the CV_BGR2BGRA not being defined: In recent openCV versions that has been renamed to COLOR_BGR2BGRA. Since the namespace isn't used, just change the bit line 103 in Texture.hpp to "cv::COLOR_BGR2BGRA", that fixes the compilation error.

[patrikhuber]

The CV_BGR2BGRA error in Texture.hpp is fixed in the latest devel branch, where we removed the dependency of OpenCV in Texture (23d0755).
