GLFW setup on OSX

[xlab]

It's very great news that 3.3 has been released! Waited for that a couple of years.
We should switch to go-gettable glfw instead of brew installed, but go-gl team has troubles updating go-gl/glfw#219

So I'll just research what could possibly cause your error using the current set of packages.

At least it will allow windows, Linux and android builds..
For osx and iOS there is no easy way , but I use a vagrant box that has osx in it. It works very well and is very easy to setup

[xlab]

I don't think Docker is a good pipeline for building desktop apps.
It's not that hard to download an .exe from the official site of GLFW, adding Docker into this won't help a bit.

I had trouble with some of the dependencies.

Then please share your troubles in an issue, so I could improve the docs for the others.

android builds..

Android build requires Android NDK & SDK, not Docker.

P.S. you're free to share any scripts that will ease the setup

thanks for the advice.
My issue stemmed from getting GLFW setup, so yes forget Docker.
I have android sdk and ndk all setup and been using it for a while.
So back to the real issue:
The issue for me was getting GLFW setup. I am on OSX.
Your Readme says i need GLFW 3.3
I tried brew install but could not get version 3.3 as they dont have it yet.
So i tried to compile and just got lost...
Maybe add to the make file? or maybe some newbie instructions in the readme ?

I was writing about master branch in the repo of GLFW, because 3.3 is needed but not yet released. You'll need to compile it with moltenVK support enabled. It autodetects moltenVK.

For OS X / macOS you'll need to install the latest GLFW 3.3 from master https://github.com/glfw/glfw

Which is

git clone https://github.com/glfw/glfw

and follow the GLFW compilation guide using cmake.

Update about Docker and cross-platform setups

NVIDIA has a Docker tool for CUDA deployments:
https://github.com/NVIDIA/nvidia-docker

They have a new nvidia-docker 2.0 currently in works, see:

http://on-demand.gputechconf.com/gtc/2017/presentation/s7177-abecassis-calmels-containers-gpu-accelerated-applications.pdf

(https://github.com/NVIDIA/libnvidia-container)

That won't be so cumbersome as the first version for CUDA, it will also support ARM and Vulkan. So until then, we will run barebones.

update: glfw 3.3 is installed by default on homebrew now with brew install glfw; however, the vulkancube_glfw demo app fails with a createLayer error. I don't know if this is go-related (v1.12.x) or I've misunderstood the info regarding cmake / the makefile. It built just fine, and detects the hardware through vulkan, it just can't open a window.
