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

I pushed gioui.org/commit/52dd762 which should remove the spurious dependency on X11 headers. Please try again, perhaps after removing your X11 dependencies.
If the example still doesn't work, please try the
debug-35branch:$ cd $(mktemp -d) $ git clone --branch debug-35 --single-branch https://git.sr.ht/~eliasnaur/gio $ cd gio/apps $ LIBGL_DEBUG=verbose go run ./helloand let me know what that outputs.
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.
https://git.sr.ht/~eliasnaur/gio/commit/c5a6ca2aba7615e0d80e3027d142e6e9686f48d8 might improve your situation as well. If you get the chance, please try out HEAD again.
I've been living under a rock and didn't notice this change: https://discourse.nixos.org/t/getting-an-error-has-anything-regarding-opengl-in-nixpkgs/3641/5
This problem is gone now and I can happily build the gophers example with these nixos deps:
nix-shell -p libGL wayland libxkbcommon
