Compiling mex file: 'mesh_boolean.cpp' with Windows10 / MATLAB 2015a / VS2015 about gptoolbox

[oqilipo]

PS: The libigl tutorial works fine (Build with 32 & 64 bit)

[alecjacobson]

Could you paste the verbose compilation flags when compiling the tutorial (when it works) and the flags that the mex is using (when it fails)?

We should be able to find a difference.

Like in the other Issue I changed to the latest stable version of eigen:

Version:
Boost: 1.60
CGAL: 4.8
Eigen: 3.2.8
libigl: https://github.com/libigl/libigl/tree/4ccac53005994f695eea123cd85e92be27caecb2

Now it works!

    axis on; axis equal
    H_Light(1) = light; H_Light(2) = light('Position', -1*(get(H_Light(1),'Position')));
    view(3)
end

Now I will test it on more complex meshes.

Thank you very much!

Excellent! So what was the trick?

see above:
I've changed from the github mirror to the latest stable version of eigen: Version 3.2.8

Thanks a lot for you help.

PS: Because I've got Matlab 2016a yesterday, I've tested the same code in 2016a and MATLAB is staying "busy" without any output. But this may be a new issue ;-)
