#35 [nixos] newContext: eglCreateWindowSurface failed 0x3009 17 days ago

Thanks for the quick reply!

The updated master helped with compiling it without depending on X11 but the error is (neary) the same:

2019/09/02 20:03:27 newContext: eglCreateWindowSurface failed 0x3009 (sRGB=true)

I will try your branch but I need to overcome a problem in the way nix re-packages the go modules since there is a bug when using the replace directive.. sigh.

in the meantime I got it working on macOS as well and bypassed this issue by using waypipe form my nixos desktop into a archlinux VM so I'm able to start using gioui to ports small experiemnts and figure this native building and running locally out later.

sorry if this is a bit arcane but I'm already using sway and other wayland apps through the nixpkgs-wayland overlay. I'm also capable of building and running other immediate mode UIs like fyne or duit but I'm having trouble correctly building/running gophers and the hello world example for gioui.

If I don't add xorg libX11 to the dependencnies I get this error:

# gioui.org/ui/app

 #include <X11/Xlib.h>
          ^~~~~~~~~~~~

If I do, I get the error in the title. From some searching I found that code is defined as EGL_BAD_MATCH but I'm not sure what that should tell me. I assume I somehow mixed incompatible library inputs but I'm not sure how to proceed. Maybe it's related to #8 ? I tried mesa and libglvnd to supply GLESv2 but since mesa pulls in the Xlib dependency I guess that might be the red herring I shouldn't have picked?

Any pointers appreciated
