Closed hajimehoshi closed 7 years ago

The Go version is 1.8.

It looks like FreeBSD is not supported yet. As github.com/go-gl/glfw supports FreeBSD, I'd like github.com/go-gl/gl to support that.

errcw commented 7 years ago

Ah, it appears freebsd is a separate build tag from linux, so it requires explicit support. I don't have a FreeBSD system at hand to develop this support, would you be interested in contributing to Glow to add the feature? In theory it could be a straightforward extension of the existing Linux support.

hajimehoshi commented 7 years ago

Sure, I'll do it later. I think simply replacing linux with linux freebsd in the templates would work. There is no unix or posix build tag, right?

errcw commented 7 years ago

Thanks for putting together the PR! Yep, AFAIK linux freebsd is the best way to represent the two platforms.

hajimehoshi commented 7 years ago

@shurcooL I've confirmed that my PR worked on Linux!

hajimehoshi commented 7 years ago

Oops, I commented at a wrong place. Sorry for disturbing

errcw commented 7 years ago

Thanks for the contribution to glow! Now we need to regenerate the go-gl/gl libraries to pull in the newly minted FreeBSD support.

Made PR #75 for that.

hajimehoshi commented 7 years ago

Great. Now I have confirmed that cube3d example in github.com/go-gl/glfw worked on FreeBSD!
