Class compilation troubles of the Matlab bindings

[vins31]

Good morning,

I would like to start with a thumb up on all the work made by the maintainers of the OpenCV and OpenCV-contrib projects.

As mentioned in this post, I have noticed the files corresponding to class bindings generated in modules/matlab/src/private/ are not compiled.
This behaviour is due to the following line in the modules/matlab/compile.cmake file

file(GLOB SOURCE_FILES "${CMAKE_CURRENT_BINARY_DIR}/src/*.cpp")
# [...]

After modifications to compiles the files in this private/ folder, I ran into various errors:

Firstly, I have seen in generator/templates/template_class_base.cpp:22

typedef std::vector<Bridge> (*)({{clss.name}}&, const std::vector<Bridge>&) MethodSignature;

I am not a C++ expert but I do not think it will generate valid C++. I think it should be:

typedef std::vector<Bridge> MethodSignature({{clss.name}}&, const std::vector<Bridge>&);
// or C++11 variant:
using MethodSignature = std::vector<Bridge> (*)({{clss.name}}&, const std::vector<Bridge>&);

Then, according to my compilers errors, I think the std::vector<Bridge>& input parameter should not be declared const.

According to some Ptr_XXX not defined, I guess this module is still a work in progress.

Environment used

• Ubuntu 12.04.2
• gcc 4.7.4
• Matlab 2014a
