commented question

Can't able to run facerec_fisherface.cpp

opencv version 2.4.9
yes in future i want to build application in android using opencv, but right now i am running the sample code(facerec_fisherfaces.cpp) using include header files(opencv2 folder files) in MinGW(g++ compiler).
No .so file used.
First of all i want to see how fisherface algorithm output is coming, So i followed steps from opencv docs and started executinf cpp files using MinGW.
If i am doing wrong way please correct me to where to start.(basically i am android developer).
