@F0rth
Thanks for the report, I honestly haven't tested it on Linux yet. Here nk_glfw3_render
crashes for some reason. You can debug with GDB (go build -work
, then gdb
) if you want.
I want to research that case, could you provide you linux workstation config? uname, distro and GCC version especially.
@F0rth I switched to http://github.com/go-gl/glfw, this may help.
so I put a breakpoint at 28 and nk-example crashed after the 74th line: ` 74 select { (gdb) n

It compiles here (latest Ubuntu Xenial) but it crashes immediately after creating the application window.
@vruz thanks for the report, I'll try to debug this case on the next weekend, tomorrow gonna move to dotGo, so no time for playing with Linux.. :(
No worries. I'd be willing to look into this problem and offload some of the work from you debugging it if you give me some rough pointers or starting directions where the problem could possibly occur. But no rush, I'll check back next week!

Related #2, probably the nuklear_glfw_gl3.h
backend for Nuklear should be replaced. Will research that this Saturday.
@F0rth @vruz guys sorry for delay. I've managed to run this thing on Windows, the problem with windows was that some old versions don't support OpenGL 3. So I migrated to OpenGL 2.1 backend and changed imports.
Please update the lib and check if this helps, because this should definitely do the trick.
No worries, thank you for following up.
Re: Windows. I'm on Linux right now, but I'll test it and see what happens.

it's working ! (on archlinux).
Gj everyone, thanks for the reports.
Hi,
nk-example crash on my workstation, which infos can I provide to help debugging this issue ?
