在Qt Creator与MinGW中配置OpenCV 2.2

Steps to build OpenCV 2.2 with Qt Creator 2.0.1 and MinGW:

1. Install Qt SDK with the C++ compiler option (MinGW). You can download ithere.

2. Add “C:<Qt_directory>/mingw/bin” to the system PATH.

3. Download and install CMake (2.8).

4. Download and install OpenCV2.2.

5. Run CMake GUI.

6. Set the source code: “C:\<OpenCV_directory>”

7. Set where to build binaries to: “C:\<build_directory>”. Example: “C:\OpenCV2.2MinGW”

8. Press Configure

9. Let CMake create the new folder.

10. Specify the generator: MinGW Makefiles.

11. Select “Specify Native Compilers” and click Next.

12. For C set: “C:\<Qt_directory>\mingw\bin\gcc.exe”

13. For C++ set: “C:\<Qt_directory>\mingw\bin\g++.exe”

14. Click Finish

15. In the configuration screen type in “DEBUG” (or “RELEASE” if you want to build a release version) for CMAKE_BUILD_TYPE. Check BUILD_EXAMPLES if you want. Check WITH_QT.

16. Click configure again.

17. The configure screen will make you specify the qmake path. It is in the Qt directory: “C:\<Qt_directory>\qt\bin\qmake.exe”

18. Click configure again. Click generate. Close CMake.

19. Go to the command prompt and go to the folder where you built your binaries (command: cd C:\<build_directory>) and type “mingw32-make” and hit enter (this might take some time).

20. Then type “mingw32-make install” and hit enter again.
