make - fatal error igl/opengl/glfw/viewer.h: No such file or directory #11

I've been trying to compile the code in my home machine for some time now, but I couldn't find the appropriate package to install for "igl/opengl/glfw/viewer.h".

Attached below is the error message after make:

[ 41%] Built target glfw [ 46%] Built target glad [ 80%] Built target core [ 82%] Building CXX object CMakeFiles/rays.dir/rays.cpp.o In file included from /home/edwardyliu/Documents/projects/computer-graphics-bounding-volume-hierarchy/rays.cpp:9:0: /home/edwardyliu/Documents/projects/computer-graphics-bounding-volume-hierarchy/include/visualize_aabbtree.h:6:36: fatal error: igl/opengl/glfw/viewer.h: No such file or directory compilation terminated.

Thank you!

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

[ 82%] Building CXX object CMakeFiles/rays.dir/rays.cpp.o In file included from /h/u8/c8/01/liuedwa1/Desktop/projects/computer-graphics-bounding-volume-hierarchy/rays.cpp:9:0: /h/u8/c8/01/liuedwa1/Desktop/projects/computer-graphics-bounding-volume-hierarchy/include/visualize_aabbtree.h:6:36: fatal error: igl/opengl/glfw/viewer.h: No such file or directory compilation terminated.

Please help!

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

What should I do?

edwardyliu commented 6 years ago

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?

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 ....

edwardyliu commented 6 years ago

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 commented 6 years ago

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?

Thank you for the help :)
