source-watcher's Issues

Sample crash while running under WSL-2 + Brew

I wanted to try building a new components, but first I tried the demo (source-watcher). I did what was in the requirements:

• flux (latest already installed)
• docker (latest already installed)
• brew install go (go version go1.16.2 linux/amd64)
• brew install kind
• brew install kustomize
• brew install kubectl
• brew install kubebuilder

Issue hit #1 When running the make:

 ~/git/github/flux/source-watcher                                                                                                                                                            09:58:33  north-pole

To fix, I did : CGO_ENABLED=0 make and it passed

Then I ran CGO_ENABLED=0 make run so that it starts. First logs seems fine but when I create the GitRepository I have the following:

make: *** [Makefile:26: run] Error 1

Any ideas what's happening? I remember not having any issues in WSL-2 with go in the past.

code incomplete

the source code is incomplete few missing definitions --

1. api/v1 directotory which is supposed to have gitrepository_types.go which has definition of GitRepository structure.

2.  artifact := repository.Status.Artifact  found in gitrepository_controller.go:63  cannot be resolved
   

3. src, ok := e.Object.(sourcev1.Source) found in gitrepository_predicate.go:33 cannot be reolved.

probably more definitions are missing, for now to highlight i have noted down these.
