Converting from pangolin::OpenGLMatrix to Eigen::Matrix while calling Make for maskfusion

[andylai2]

I am having issues building maskfusion. Everything has built properly until the final step, after calling cmake in the maskfusion/build directory and then calling make.

I am getting an error in the file maskfusion/Core/Shaders/FeedbackBuffer.cpp

Here is the error message:

maskfusion/Core/Shaders/FeedbackBuffer.cpp: In member function 'void FeedbackBuffer::render(pangolin::OpenGlMatrix, const Matrix4f&, bool, bool)':
maskfusion/Core/Shaders/FeedbackBuffer.cpp:133:45: error: no matching function for call to 'Uniform::Uniform(const char[4], pangolin::OpenGlMatrix&)' drawProgram->setUniform(Uniform("MVP", mvp));

It looks like a fix I can apply is by editing FeedbackBuffer.cpp to manually convert mvp into an Eigen matrix, but I don't know what dimensions it needs to be.

In Core/Shaders/Uniform.h there is no matching function that takes in an OpenGlMatrix as a parameter.

Never mind, I fixed this by starting a clean build and installing Eigen before Pangolin. If it is done in the wrong order then this issue will arise.
