Go 语言学习笔记 1 （安装开发环境）

    本文只针对Ubuntu系统开发环境的搭建进行学习。

    本文工作操作系统为ubuntu12.12.

第一步，安装Go工具链：

root@tangle-VirtualBox:/home/tangle# sudo apt-get install bison ed gawk gcc libc6-dev makeReading package lists... DoneBuilding dependency tree       Reading state information... Doneed is already the newest version.gcc is already the newest version.libc6-dev is already the newest version.make is already the newest version.The following extra packages will be installed:  libbison-dev libsigsegv2Suggested packages:  bison-docThe following NEW packages will be installed:  bison gawk libbison-dev libsigsegv20 upgraded, 4 newly installed, 0 to remove and 160 not upgraded.Need to get 760 kB of archives.After this operation, 2,998 kB of additional disk space will be used.Do you want to continue [Y/n]?

第二步 安装Mercurial版本管理系统

root@tangle-VirtualBox:/home/tangle# apt-get install mercurialReading package lists... DoneBuilding dependency tree       Reading state information... DoneThe following extra packages will be installed:  mercurial-commonSuggested packages:  qct wish kdiff3 tkdiff meld xxdiff python-mysqldb python-pygmentsThe following NEW packages will be installed:  mercurial mercurial-common0 upgraded, 2 newly installed, 0 to remove and 23 not upgraded.Need to get 1,982 kB of archives.After this operation, 6,691 kB of additional disk space will be used.Do you want to continue [Y/n]? YGet:1 http://cn.archive.ubuntu.com/ubuntu/ precise/universe mercurial-common all 2.0.2-1ubuntu1 [1,945 kB]Get:2 http://cn.archive.ubuntu.com/ubuntu/ precise/universe mercurial i386 2.0.2-1ubuntu1 [37.1 kB]Fetched 1,982 kB in 4s (490 kB/s)Selecting previously unselected package mercurial-common.(Reading database ... 155146 files and directories currently installed.)Unpacking mercurial-common (from .../mercurial-common_2.0.2-1ubuntu1_all.deb) ...Selecting previously unselected package mercurial.Unpacking mercurial (from .../mercurial_2.0.2-1ubuntu1_i386.deb) ...Processing triggers for man-db ...Setting up mercurial-common (2.0.2-1ubuntu1) ...Setting up mercurial (2.0.2-1ubuntu1) ...Creating config file /etc/mercurial/hgrc.d/hgext.rc with new versionroot@tangle-VirtualBox:/home/tangle# 

 

第三步 获取go语言源代码

root@tangle-VirtualBox:/home/tangle# hg clone -r release https://go.googlecode.com/hg/ goadding changesetsadding manifestsadding file changesadded 16303 changesets with 58951 changes to 8102 filesupdating to branch release-branch.go1.13747 files updated, 0 files merged, 0 files removed, 0 files unresolvedroot@tangle-VirtualBox:/home/tangle# 

第四部 编译并安装go

root@tangle-VirtualBox:/home/tangle# cd go/src/root@tangle-VirtualBox:/home/tangle/go/src# ./all.bash # Building C bootstrap tool.cmd/dist

 

中间编译过程在此略过，如果安装成功最后会出现如下信息

# Checking API compatibility.Go version is "go1.1.1", ignoring -next /home/tangle/go/api/next.txt~pkg net, func ListenUnixgram(string, *UnixAddr) (*UDPConn, error)~pkg syscall (darwin-386), func Fchflags(string, int) error~pkg syscall (darwin-386-cgo), func Fchflags(string, int) error~pkg syscall (darwin-amd64), func Fchflags(string, int) error~pkg syscall (darwin-amd64-cgo), func Fchflags(string, int) error~pkg syscall (freebsd-386), func Fchflags(string, int) error~pkg syscall (freebsd-amd64), func Fchflags(string, int) error~pkg text/template/parse, type DotNode bool~pkg text/template/parse, type Node interface { Copy, String, Type }ALL TESTS PASSED---Installed Go for linux/386 in /home/tangle/goInstalled commands in /home/tangle/go/bin*** You need to add /home/tangle/go/bin to your PATH.

 

    按照安装完成后的提示信息将/home/tangle/go/bin 添加到PATH环境变量中

root@tangle-VirtualBox:/home/tangle/go/src# export PATH=$PATH:/home/tangle/go/binroot@tangle-VirtualBox:/home/tangle/go/src# echo $PATH/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/tangle/go/bin

 

最后， 编写hello world 验证开发环境

root@tangle-VirtualBox:/home/tangle/go/go-test# cat hello.go package mainimport "fmt"func main() {        fmt.Printf("hello, world\n")}root@tangle-VirtualBox:/home/tangle/go/go-test# root@tangle-VirtualBox:/home/tangle/go/go-test# go build hello.go root@tangle-VirtualBox:/home/tangle/go/go-test# lshello  hello.goroot@tangle-VirtualBox:/home/tangle/go/go-test# ./hello hello, world
