Switching to OpenCV 2.0 with VS2005
I’m using OpenCV for some tests, and for some reasons (freelance gigs and Symbian SDK) using MS Visual Studio. As new and shiny OpenCV 2.0 is out I decided to switch to it. As it happen, one absolutely have to read buried in the download section readme, before doing anything.
The thing is, OpenCV 2.0 doesn’t include lib files for VS. They have to be built by user.
So here is step by step retelling of readme:
1. Rename your old OpenCV installation to save it, just in case
2. Download and install OpenCV 2.0a
3. Download and install CMake
4. Reboot (or CMake wouldn’t work)
5. Go to C:\Program Files\CMake 2.6\bin and run cmake-gui.exe
6. In the “Where is the source code” field choose your new OpenCV directory (C:\OpenCV)
In “Where to build the binaries” choose directory for VS compiled OpneCV (C:\OpenCV\VS2005)
7. press Configure button and choose VS2005 (or whatever) as building enviroment
8. Press Generate and VS project will be generated in the C:\OpenCV\VS2005
9. Launch solution and build it. For debug build some projects require debug python libraries. As riseriyo pointed in comments if you have Python installed other than 2.6 that can cause problem.
10. Copy *.lib from C:\OpenCV\vs2005\lib\release (or debug) to C:\OpenCV\lib
Copy *.dll from C:\OpenCV\vs2005\bin\release to C:\OpenCV\bin
11. Now, reconfigure your application project. Include directories now “C:\OpenCV\include\opencv” instead of “C:\OpenCV\include
12. All libraries renamed from *.lib to *200.lib (cv.lib to cv200.lib) or *200d.lib for debug. Rename them, or change project settings.
PS if you need Python and still have a problem with cvpy:
1. Python 2.6 bindings for OpenCV are included within the package,
but not installed.
You can copy the subdirectory opencv/Python2.6/Lib/site-packages into
the respective directory of the Python installation.
Here is riseriyo explanation how he deal with python problem
PPS Comment by rise about vs2008 issue:
dll and manifest file version conflict in msvc 2008. the only way i was able to fix this was to completely uninstall msvc 2008 and then do a clean install w/o updating it with the sp1 packages.
see his blog and how he was troubleshooting (for days) the issue
PPPS As Niklas pointed out if you have omp.h not found error, that mean you forgot to turn off OpenMP in CMake.
That’s it. Project should compile now. If not you still have your old OpenCV installation
