Compiling freak_demo.cpp - error

edit

Has anyone been able to compile freak_demo.cpp in OpenCV 2.4.2? Everything else compiles besides this. I get this error,

compiling freak_demo.cpp
freak_demo.cpp: In function ‘int main(int, char**)’:
freak_demo.cpp:93:5: error: ‘FREAK’ was not declared in this scope
freak_demo.cpp:93:11: error: expected ‘;’ before ‘extractor’
freak_demo.cpp:110:5: error: ‘extractor’ was not declared in this scope

This is what I get after compiling the samples/cpp/ folder:
