[Question] can't generate the call graph for hashicorp/raft #15

Closed smallnest closed 6 years ago

smallnest commented 6 years ago

I use the below command"

go-callvis -focus github.com/hashicorp/raft github.com/hashicorp/raft -limit github.com/hashicorp/raft -nostd

but there are many errors:

Maybe I have made a mistake to use it.

My question is how to use it for github.com/hashicorp/raft github.com/hashicorp/raft

ondrajz commented 6 years ago

Try putting the target package argument github.com/hashicorp/raft after all the flags, like this:

go-callvis -focus github.com/hashicorp/raft -limit github.com/hashicorp/raft -nostd github.com/hashicorp/raft

Thanks @TrueFurby , but it still has some errors:

go-callvis -focus github.com/hashicorp/raft -limit github.com/hashicorp/raft github.com/hashicorp/raft

go-callvis: couldn't load packages due to errors: github.com/hashicorp/raft, github.com/hashicorp/go-msgpack/codec, github.com/armon/go-metrics and 2 more
ondrajz commented 6 years ago

This seems like issue with compiling the package github.com/hashicorp/raft itself.

Try running: go install github.com/hashicorp/raft

I tried downloading it and compiling with go 1.8.3 successfully. What Go version do you use?

smallnest commented 6 years ago

Go 1.9.

I have updated "raft" : go get -u github.com/hashicorp/raft

ondrajz commented 6 years ago

So, it works now?

smallnest commented 6 years ago

No, same problems to the above. It looks it can't find stdlib:

You have GOROOT set to /usr/local/go, but for some reason during the compilation it seems to using /usr/local/Cellar/go/1.7.4/libexec/ to look for stdlib.

smallnest commented 6 years ago

It should be caused by this. I have ever installed go by brew but I have uninstalled it then. Now I install go manually. It is not an issue of go-callvis.

I will investigate how to fix it .

Thanks @TrueFurby
