A little description about my environment: DevCpp 4.9.9.2 with OpenCV 2.3.1 on Windows Vista Home Premium SP1 32-bit

About my project - my project's .dev (FirstCVproj.dev) file is in c:...\Desktop\proj\openCV\ and the program i'm trying to compile "facedetect.cpp" is in c:\opencv\samples\c

The OpenCV compiler configuration in the tools->compilers in DevCpp is:

Compiler commands

-L"C:\opencv\build\x86\mingw\lib" -llibopencv_core231 -llibopencv_imgproc231 -llibopencv_calib3d231 -llibopencv_video231 -llibopencv_features2d231 -llibopencv_ml231 -llibopencv_highgui231 -llibopencv_objdetect231 -llibopencv_contrib231 -llibopencv_legacy231 -llibopencv_flann231
Linker commands

-llibopencv_core231 -llibopencv_imgproc231 -llibopencv_calib3d231 -llibopencv_video231 -llibopencv_features2d231 -llibopencv_ml231 -llibopencv_highgui231 -llibopencv_objdetect231 -llibopencv_contrib231 -llibopencv_legacy231 -llibopencv_flann231
Libraries directory: opencv\build\x86\mingw\lib

Binaries directory: opencv\build\x86\mingw\bin

Include directories: all the include folders in opencv folder (under the \build and the main folder)

So before I decided to post here, i was having the problems stated here and in that order:

libgcc_s_dw2_1.dll not found. Try reinstalling the application

Program can't find libgcc_s_dw2-1.dll

libstdc++-6.dll not found. Try reinstalling the application libstdc++-6.dll not found

Because using -static or -static-libgcc or -static-libstdc++ in linker command line options box did not work for me, i copied the first dll file to my project directory from some other directory in my system where i found it (and nowhere in mingw32 folder in C:\DevCpp) and downloaded the second one off the net, my project stopped giving run-time errors like "FirsCVProj has stopped working. Contact the application vendor for support" or ".dll was not found"

But it became worse, because at runtime, i did see the command output window of the program i was compiling in my project, but that just appeared for like a fraction of a second!

I rebuild the whole thing a couple of times, but then remembering Einstein's quote "Repeating the same thing and expecting a different output is insanity" i stopped.. That's where you guys come in. Here's the compilation log from which i can't help wondering why the files aren't linking.

i also tried opencv\samples\c\mushroom.cpp and i got the output window in which the details of the program were printed, about its author etc, but then i got the windows message: "FirstCVproj has stopped working"
