compile issue

[rnunziata]

I was getting the following bug

Track.cpp:73:30: error: ‘setw’ was not declared in this scope

but fixed it by adding the line at the top of the file.

include

Now it fails with following errors....not sure what to do?

Do you have OpenCV installed on your system? (If so, perhaps there's some sort of version clash. I will have to double check which exact version is needed.)

Otherwise, maybe try adding #include <opencv/cv.h> to the problematic file(s).

Apologies for the vague responses, it's just that I temporarily do not have access to a system with an nVIDIA GPU and CUDA so that I can test these things.

I have installed opencv 3.3, however I think I can get around this...its the Eigen error that I am not sure what to do about.

[AndreiBarsan]

Hmm, so the return Eigen::Matrix4d((~viso_matrix).val[0]); is causing an error? Again, I can't try out any changes right now (really sorry!), but can you try making a (non-const) copy of viso_matrix, transposing it (using the ~ operator), and using val[0] to construct an Eigen matrix?

[rnunziata]

Eigen::Matrix4d VisoToEigen(const Matrix &viso_matrix) { // The '~' transposes the matrix... Matrix a=viso_matrix; return Eigen::Matrix4d((~a).val[0]); }

got pass with this mod....
