We have been shipping OpenCV 2.4.6 prebuilt dlls for several years in our commercial product. We are preparing a new release and want to upgrade to using the prebuilt libraries for OpenCV 3.2. We use VS 2015

1. Is there a list of changes we must make to our code to use the new version of OpenCV? Or is it simply a matter of dropping in the new dlls and rebuilding?

2. I downloaded opencv-3.2.0-vc14.exe and extracted the file. I found the "world" dll under \x64\vc14. Since we are building 32 bit apps does that mean I cannot use the prebuilt libraries. Are 32 bit versions available somewhere else? Or will we have to start building our own dlls form the OpenCV source.

Thanks

When I am stopped at a break point and add a Mat object to the watch window, visual studio displays "foo {...}" (foo is the name of the Mat object). I have no option to to examine the contents of the Mat object. Typically there is a plus sign to the left of the variable name to expand the object.

I am using the distributed openCV debug dlls for V2.4.4. I don't have the PDBs but I shouldn't need the pdbs just to examine the content of a Mat object.

The OpenCV calls are in a "Managed C++" project. A few months ago I was working on the same code on my old PC and I did not have this problem. On my new PC I have manually placed the openCV debug dlls into the same folder as the app. i.e. I have not set up any path or environment variables.

The old PC is W7 the new is W8. I have VS2012 update 2. I am compiling and linking with the debug setings and I've check "enable managed code debugging" in my aplication project. I installed the ImageWatch and that did not recognize any Mat objects either.

Any ideas?

"USB3 Vision" is an industry standard for connecting cameras to computers over USB 3. Read about it here

I've downloaded OpenCV from here:

http://sourceforge.net/projects/opencvlibrary/files/opencv-win/

This gave me and exe. When run it expanded into a bunch of folders and files.

Then I followed the instructions for installing on windows:

http://docs.opencv.org/doc/tutorials/introduction/windows_install/windows_install.html#windows-installation

The above instructions say there should be a "bin" folder, and they also say to start and follow the "set up wizard".

I don't have a bin file or a "setup" program to run. It seems like I probably just have the source files. I've googled around and most blogs, websites etc all point to the SourceForge download folder that I used.

Is there another place to get the pre built dlls. Or does everyone end up building them?

Thanks,

Mitch
