macOS

[coolbutuseless]

I got it to compile OK on macOS using the following Makevars (with 'glfw` and 'glew' installed via homebrew)

PKG_CPPFLAGS = -I. -I/opt/homebrew/include
PKG_LIBS = -lglfw -lm -L/opt/homebrew/lib -framework Cocoa -framework OpenGL

However, trying to run camera_mouse_zoom.R fails here:

> program <- build_program(vert = vs, frag = fs)
Error in build_program(vert = vs, frag = fs) : 
  Validation Failed: No vertex array object bound.

Thanks @coolbutuseless for reporting this issue. I need to get my hands on a macOS to debug this.

As per this post: https://stackoverflow.com/questions/54181078/opengl-3-3-mac-error-validating-program-validation-failed-no-vertex-array-ob, could you try:

moving these lines:

vs <- system.file("tutorials/learnopengl/camera/camera.vs", package = "glfw")
fs <- system.file("tutorials/learnopengl/camera/camera.fs", package = "glfw")
program <- build_program(vert = vs, frag = fs)

to line 196 of camera_mouse_zoom.R:

gl_enable_vertex_attrib_array(1L)

That did the trick!

That's awesome!
