Get OpenCV2.1 to run in windows using eclipse

Question

Hi, I am trying to get OpenCV2.1 to run on my windows machine. Here is what I have done so far:

• Installed MinGW using MinGW-get-inst
• Installed Visual Studio C++ 2008 Express
• Installed OpenCV-2.1.0-win32-vs2008.exe downloaded from OpenCV's website
• Installed Eclipse

Then to test everything, I created a new project, and:

• Configured Eclipse to include "C:\OpenCV2.1\include\opencv"
• Configured Eclipse to see libraries cv210, highgui210, ml210, cxcore210
• Configured Eclipse to see library folder "C:\OpenCV2.1\lib"

I then took a test source code from the Samples folder (lkdemo.c), put it in my source folder, and built the source (Project-->Build All).

The build is successful, and I see a Test.exe (called my project Test). However, when I try to run the exe file, I get the error:

The program can't start because libgcc_s_dw2-1.dll is missing from your computer. Try reinstalling the program to fix this problem.

What did I miss? I may be mistaken, but I thought MinGW was the gcc compiler?

Thanks,

First you probably want to download the opencv2.1 src for eclipse/mingw not the vs-2008 libs.

"libgcc_s_dw2-1.dll" means it can't find that dll at runtime, it needs to be on the path.
I'm guessing from the name that it's part of mingw/gcc install?
Do a search of the C: drive for this file.
