在Linux（Mint）中安装Go并修改bashrc

Question

I want to install Google's Go Language on my Linux Mint machine. I'm new to Linux so its not easy to follow some of the instructions I have read. Namely, I have been told to edit/mod the bashrc file:

 export GOROOT=$HOME/gosource
 export GOARCH=amd64
 export GOOS=linux
 export GOBIN=$HOME/bin
 export PATH=$PATH:$GOBIN

I don't know how to do this. I typed gedit ~/.bashrc

into the terminal and a blank page appeared. I put in the code and saved it. Then did

hg clone -u https://go.googlecode.com/hg/ go

to get the source code. Is this correct? Because I then tried to compile the code and a long list of errors appeared (which I don't have - I'm using a different PC at the mo unfortunately).

But if anyone can help me install Go, I'd appreciate it.

SOLUTION:

Aside from various problems mentioned and solved in the answers below, I had forgotten to install the following

sudo apt-get install bison ed gawk gcc libc6-dev make

WHich is mentioned at the top of the golang.com install page.

Amongst other things, you tried to clone the repository to ~/go and edited ~/.bashrc to point $GOROOT to ~/gosource.

Read the Go Getting Started instructions carefully. Either copy and paste commands or check what you type very carefully; check input very carefully before you hit enter. For commands, the $ sign represents the command prompt, don't type it. Remember, Linux is case sensitive and the distinction between / and \ is important. Check the output of commands very carefully; does the ouput make sense. Run diagnostic commands like env, pwd, which, and uname. When you see scroll bars in a Stack Overflow answer, scroll through all the code and output.

First, set up ~/.bashrc.

$ gedit ~/.bashrc

export GOROOT=$HOME/go
export GOARCH=amd64
export GOOS=linux
export GOBIN=$GOROOT/bin
export PATH=$PATH:$GOBIN

Close any open terminal windows and then open a new terminal window to check the new ~./bashrc and other values.

$ env | grep '^\(GO\|HOME=\|PATH=\)'
GOBIN=/home/peter/go/bin
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/peter/go/bin
GOARCH=amd64
HOME=/home/peter
GOROOT=/home/peter/go
GOOS=linux
$ cd $GOROOT/src
$ pwd
/home/peter/go/src
$ uname -a
Linux peter 2.6.32-31-generic #61-Ubuntu SMP Fri Apr 8 18:25:51 UTC 2011 x86_64 GNU/Linux

Then clone the repository to $GOROOT and you will clone to and compile from the same place.

$ hg clone -u release https://go.googlecode.com/hg/ $GOROOT

You haven't posted your output, so I can only guess what your problems are.

For example, you say "the directory is Go", it should be "go"; since Linux is case sensitive, "Go" and "go" are different.

If you omit the $GOROOT destination from the hg clone command or $GOROOT is not set, hg clone will default to the hg directory. For example,

$ env | grep '^GOROOT'
GOROOT=
$ hg clone -u release https://go.googlecode.com/hg/ $GOROOT
destination directory: hg

Since you have GOARCH=amd64, you should be running a 64-bit version of Linux Mint on an x86_64 processor. What does your uname -a output say? You want the 6g and 6l programs to compile and link on an x86_64 processor, which should be in your $GOBIN directory, which should be in in your $PATH.

$ env | grep '^\(GOBIN\|PATH=\)'
GOBIN=/home/peter/go/bin
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/peter/go/bin
$ which 6g
/home/peter/go/bin/6g

You should also have seen this by reading the end of your ./all.bash command output.
