Question content

So I just upgraded my go version to a higher version go1.20.2 Previously I used go1.18.x.

I have updated the environment path of go

<code>export GOPATH="$HOME/go";
export GOROOT="$HOME/.go"; 
export PATH="$GOPATH/bin:$PATH";
</code>

So, every time I try to build it always shows these errors

<code>/home/usr/.go/src/net/cgo_resnew.go:21:17: could not determine kind of name for C.getnameinfo
</code>

I've been looking for the answer but I didn't get it from the internet. Does anyone know what causes this error?

When to do it

<code>go build .
</code>

It should not show this error

/home/usr/.go/src/net/cgo_resnew.go:21:17: could not determine kind of name for C.getnameinfo

Solution

Use the command go env to check CGO_ENABLED in the golang environment. If your value CGO_ENABLED is 1, you must set the value to 0. If you use zsh, add export CGO_ENABLED=0 on ~/.bashrc or ~/.zshrc (I recommend adding environment variables on ~/.profile for global settings)
