I am trying use the latest release of kubebuilder (2.3.1) and initialize a project by running kubebuilder init --domain my.domain

kubebuilder init --domain my.domain Writing scaffold for you to edit...

What versions of software are you using? Specifically, the following are often useful: kubebuilder version Version: version.Version{KubeBuilderVersion:"2.3.1", KubernetesVendor:"1.16.4", GitCommit:"8b53abeb4280186e494b726edf8f54ca7aa64a49", BuildDate:"2020-03-26T16:42:00Z", GoOs:"unknown", GoArch:"unknown"}

go version go version go version go1.13.14 linux/amd64
kubebuilder version (kubebuilder version) and scaffolding version (check your PROJECT file) 2.3.1
controller-runtime version (check your go.mod file)
controller-tools version
Kubernetes & kubectl versions (just run kubectl version against your API server)

Hi @jsarkar,

As we spoke in the slack I am unable to reproduce the issue using the version informed. So, could you please: a) could you let us know if you are using it inside or outside of your $GOPATH?

Note If you are not familiarised with Go, I'd recommend you perform the steps inside of your $GOPATH in order to keep the simplicity. for further information see the notes in https://book.kubebuilder.io/quick-start.html

mkdir $GOPATH/src/example
cd $GOPATH/src/example
kubebuilder init --domain my.domain

b) Could you please provide your Go env? (Output of the command $go env) c) Could you please try to verify your go installation first by following these steps? Is it working for you?

Also, it really shows a Go setup issue. See: https://forum.golangbridge.org/t/cgo-build-error-help-me/16077/3

@camilamacedo86 I have tested inside and outside GOPATH. However the below snippet shows , I am trying initialize kubebuilder inside GOPATH

joysarkar@jsarkar:~/projects/gocode/src/example$ direnv allow
direnv: loading ~/projects/gocode/src/example/.envrc
direnv: export +GOPATH ~PATH
joysarkar@jsarkar:~/projects/gocode/src/example$ cd $GOPATH/src/example

Here is my goenv o/p

I have tested my GO installtion also

joysarkar@jsarkar:~/projects/gocode/src/example$ vi hello.go
joysarkar@jsarkar:~/projects/gocode/src/example$ go build hello.go 
joysarkar@jsarkar:~/projects/gocode/src/example$ ./hello 
hello, world

My laptop is not arm nither I am trying cross-compile CGO. So really not sure what to follow the issue link you have refered.

jsarkar commented 4 years ago

I have noticed some how my default CGO config is enabled (CGO_ENABLED="1"). I have disabled and now I am able to initialize the project. I am good here and will close the issue
