Setting up opencv on DEV C++

This is really simple if you know what to do .

1. Download OpenCV : install ; check the path where it is installed. for eg C:\Opencv2.x
2. Download DevCPP: install ;

Once done with both

Open Dev Cpp.Go to TOOLS - COMPILER OPTIONS . ADD new compiler (click on plus sign).

Name it OpenCV.

Add these lines and tick

Add these foll commands while calling compiler

-L"C:\OpenCV\lib" -lcxcore210 -lcv210 -lcvaux210 -lhighgui210 -lml210

while doing so change the lib path( C:\OpenCV\lib) according to the path you have saved.GO to the lib folder in opencv dir and check for the above files linked .eg cxcore210 check if there is some other name instead and replace accordingly.

Add these lines and tick

Add these foll commands to the linker command line

-lcxcore210 -lcv210 -lcvaux210 -lhighgui210 -lml210

Now go to Directories

first in Binaries Add path to opencv Bin folder

C:\OpenCV\bin

again change it according to your bin path

then go to Libraries Add path to opencv Lib folder

C:\OpenCV\lib

again change it according to your lib path

then go to C includes Add path to opencv Include folder

C:\OpenCV\include

again change it according to your include path

then go to C++ includes Add path to opencv Include folder

C:\OpenCV\include

again change it according to your include path

Now go to Environment Variables and edit path variable

and add Opencv/bin to path and save.

Again the bin path should be according to your install dir opencv path. change it accordingly.

click ok and your are done .

go to samples and run them.
