I was trying to build wl project, using my "release" build of gollvm.

~/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

~/golang_projects/wl/ui/examples/img$ 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'

Running a pre-compiled executable lad to this:

~/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
. This is some sort of misconfiguration, on Ubuntu 20.04, related to Wayland.
I will try to resolve this, to ensure that there wouldn't be any other runtime issues.

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

Dup of #41881.
