REPORTED RESOLVED FIXED
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
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 In file included from /nix/store/85mw8g12qysnhiyw49vjp426jp210cdn-mesa-19.1.3-dev/include/EGL/egl.h:39:0, from ../firstname.lastname@example.org/app/egl_linux.go:8: /nix/store/85mw8g12qysnhiyw49vjp426jp210cdn-mesa-19.1.3-dev/include/EGL/eglplatform.h:124:10: fatal error: X11/Xlib.h: No such file or directory #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_MATCHbut 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
