How to compile

I assume you have finished to set an environment up to compile original OpenCV codes.

Find haartraining/ directory in OpenCV source code directory tree. Copy vec2img.cpp to haartraining/ directory. If you are working on linux,

$ g++ `pkg-config --cflags opencv` `pkg-config --libs opencv` -o ve2img vec2img.cpp cvboost.cpp cvcommon.cpp cvsamples.cpp cvhaarclassifier.cpp cvhaartraining.cpp

This is an usual way of compiling OpenCV codes, except that it requires cvboost.cpp cvcommon.cpp cvsamples.cpp cvhaarclassifier.cpp cvhaartraining.cpp together.
