How to compile golang

Golang compilation method:

1. Use the go build command to compile

The go build command is used to compile what we specify source code files or code packages and their dependent packages.

For example, if we execute the go build command without any code package, the command will try to compile the code package corresponding to the current directory. For example, we want to compile the code package logging of the goc2p project. One of the methods is to enter the logging directory and execute the command directly:

hc@ubt:~/golang/goc2p/src/logging$ go build

Because there are only library source files and test source files in the code package logging, there will be no files in the current directory and goc2p project after executing the go build command. pkg directory to generate any files.

2. Use the go install command to compile

go install just places the compiled intermediate files in the pkg directory of GOPATH, and permanently places the compilation results in GOPATH bin directory.

This command is actually divided into two steps internally: the first step is to generate the result file (executable file or .a package), and the second step will move the compiled results to $GOPATH/pkg Or $GOPATH/bin.

Use go install to execute the code, refer to the following shell:

$ export GOPATH=/home/davy/golangbook/code
$ go install chapter11/goinstall

Golang’s go build and go install commands can generate executable files.

go install and go build will be compiled in the current directory when run without parameters. If the current directory is the software main program (package main)

go build will generate an executable file and place it in In the current directory, go install will put it in $GOPATH/bin.

go install will also compile the imported dependency package to $GOPATH/pkg and cache it. If the package has not been changed, the cache will be used directly for the next compilation. The go build command plus parameter -i can also achieve the effect of go install.
