[SOLVED] 6g: command not found error while compiling external API code in Go

6g: command not found error while compiling external API code in Go

I'm new to golang and I'm trying to write a program using this tutorial.

However I'm getting this error thrown while compiling it.

6g: command not found

Here's what I've tried:

$ go version
go version go1.4.1 darwin/amd64

I've set environment variables properly

Here's how my .bashrc looks like:

 $ tail ~/.bashrc

export GOBIN=/Users/abhijeet/code/golang/go/bin  
export GOROOT=/Users/abhijeet/code/golang/go  
export GOPATH=/Users/abhijeet/code/golang/gopath  
export GOOS="darwin"  
export GOARCH="amd64"  
export PATH="$GOBIN:$PATH"

I've added below line under /etc/profile to source it

Here's how it looks:

[ -r $HOME/.bashrc ] && source $HOME/.bashrc

If I quit the terminal, launch it again and echo any of the variables, they work.
I have gcc installed.

Here's what I get when I run "gcc --version" command:

$ gcc --version

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/c++/4.2.1
Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin14.1.0
Thread model: posix

If I write any other go program and run it, it works. For instance, all the programs from section 1 through 5 from here, and till the "Go Templates - Part 3 - Template Sets" work just fine even now. Only this particular tutorial is troubling me.
None of the other programs I just gave link to, required me to run the "6g" command. But they still run on my machine.
About the line where I get error, I am using the right one to reflect folder names in my machine.

What they've asked to run:

6g -I $GOPATH/pkg/linux_amd64 urlshortener.go

What I'm running:

6g -I $GOPATH/pkg/darwin_amd64 urlshortener.go

Important: I have followed all the steps in the tutorial for using external apis. However, if I look inside the darwin_amd64 folder, I don't see any urlshortener.go file at all!

All I can find is

darwin_amd64
├───code.google.com
│   ├───p
│   │   └───google-api-go-client
│   │       └───googleapi
│   │       │    └─── <more folders and files here>
│   │       └───urlshortener 
│   │       │   └───v1.a
│   │       └───googleapi.a
│   │

So I know there's some problem there, but I also know that this probably isn't what is causing the error I'm seeing, otherwise I would have seen the error like "file not found". I just wanted to mention it as an additional data.

So I appreciate any help on this. Please let me know if I should provide any additional data as well.

Solution

It's an internal command, you can run it with go tool 6g.

That being said, that guide is extremely outdated and not relevant anymore.

To compile I used: 6g -I $GOPATH/pkg/linux_amd64 urlshortener.go

To link I used: 6l -L $GOPATH/pkg/linux_amd64 urlshortener.6

Is replaced with simply running go build urlshortner.go or even go run urlshortner.go
