make - fatal error igl/opengl/glfw/viewer.h: No such file or directory about computer-graphics-bounding-volume-hierarchy

[velociraptor111]

wow that is so weird ... I have mine in lower case and it is working on my mac.

Out of curiosity , I tried cloning the repo and tried building the project in the UG machine at uoft and it has the same error as yours! but it is definitely working on my mac.

I'd suggest try running it and you should see a diagram pop up. If it does, then I suggest just keep on working so that you are not stuck on it until Professor Alec responds to this issue ....

I tried again to compile it using the CDF computers, I got the same error message:

Please help!

I dug around and found the file that was "missing":

What should I do?

[edwardyliu]

It compiled when I changed:

"#include <igl/opengl/glfw/viewer.h>" to "#include <igl/opengl/glfw/Viewer.h>"
in "include/visualize_aabbtree.h"

Is this an appropriate change to make?

[edwardyliu]

It ran: ray, distance, and intersection; different images popped up in all 3.

There were no errors though, just the image, which I'm not sure if it's suppose to be like this or not; since I didn't write any code at all yet.

[velociraptor111]

Yes I think you are good then. The images should look something like in the readme.

Wow, sucks you have to go through this debugging man lol. Just curious, what machine are you using?
