I tried to solve 40988# by compiling the file at Ubuntu WSL, Ubuntu inside Windows 10.

I got go installed and running:

$ go version
go version go1.15 linux/amd64

I got gcc installed and running
image

While compiling the same code, I got the below error:

output:

Please show us text as plain text, not as an image. Thanks.

First, you need to set CGO_ENABLED=1. But that won't be enough: in order to cross-compile a Go program that uses C code, you need to have a C cross-compiler. Go cross-compiles automatically, but C does not.

Closing because this is not a bug. We don't use the issue tracker for questions. You will get better and faster help using a forum. Please see https://golang.org/wiki/Questions. Thanks.
