Hi.

$ go version

I got such errors:

~/golang_projects/wl/ui/examples/img$ go run image.go
/tmp/go-build853824791/b001/exe/image: symbol lookup error: /lib/libgo.so.12git: undefined symbol: main.main
exit status 127

$ file /lib/libgo.so.12git
/lib/libgo.so.12git: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, with debug_info, not stripped

~/golang_projects/wl/ui/examples/img$ go run img.go

command-line-arguments

./img.go:39:14: error: reference to undefined name 'ImageFromFile'

This one seems to be related to Wayland itself - so I will try resolve that (manually):

$ ~/go/bin/img ~/go/src/github.com/dkolbly/wl/ui/examples/img/bsd_daemon.jpg
Connect to Wayland server failed dial unix /run/user/1000/wayland-0: connect: no such file or directory

Same as #41880. Which one do you want to keep?

Probably the second one.
Thanks, @ianlancetaylor

I would not expect go run image.go to work, as the main function is in img.go.

I don't think this is a bug at all.
