Hello, guys.

I'm having some dificulties to install OpenCV using Windows 7 x86. I tried to use CMake, and even though the configuration and generating succeeded, some things got "failed". And then I've opened the windows CMD, used the "mingw32-make" at the binaries folder and OK, it started to compile, but when it starts to build something named "algorithm.cpp.obj", I got an error! Does it have any relation with the things that failed when I used CMake? Do I have to download any library to make it work?

P.S: I've searched for some tutorials online and followed them step by step, but I couldn't install anyway!

P.S(2): I want to use it with QT.

P.S(3): I'm not even an average programmer.

1) Yes, if there is any failure in CMake, you will fail while compiling.

Do not ignore any error or even warning in CMake by keep pressing "configure".

Fix the error or warning in CMake configure log.

When you selecting "with XXX", make sure you have XXX on your computer or it will be build by OpenCV.

2) Put more information about the failure in CMake or compiling, so people can give you more specific suggestion.

3) You can install Qt5 before configuring OpenCV 2.4.6 . Then in CMake, selecting "with Qt".

Use "Grouped" and "Advanced" well to check if there is any failure about finding Qt.

have you checked that? if not, check the guide that i am pointing to in my answer. The guide is about opencv 2.4.5 but it is the same walkthrough for the newer versions of opencv. Cheers.
