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:

you'd better specify the OS you developing for and the source code...

Using Ubuntu 12.04 64bit. The source code is freakdemo.cpp in the C++ samples folder in OpenCV (OpenCV-2.4.2/samples/cpp/freakdemo.cpp)

SOLVED! Update cmake to 2.8.8

You need to specify the include path when you compile

in Ubuntu, add

gcc [... other options]  -I/path/to/opencv/module/include/

@sammy Can you give an example of an include path you will use because I can't seem to find it. I also don't think that is the problem because the "include" files are included since everything else compiles except facerec.cpp, filestorage.cpp and freakdemo.cpp. Check the edited question to see what I get after compiling the samples/cpp/ folder.

It seems the Makefile has some problems. It crashes in the newly added samples. I hope someone with more experience in OpenCV builds will look at it. You may want to file a bug on it.
