Golang's HelloWorld

This is a created article in which the information may have evolved or changed.

New source file Hello.go

mkdir -p/work/gotest//work/gotest/vim hello.go

Encode Hello.go file:

"FMT"func Main () {    fmt. Printf ("Hello world\n")}

Run directly:

Go Run hello.go

Run will be a bit slow, because Golang to first compile the source code and then run.

Now, let's compile the source file into a binary file:

cd/work/-o hi.out

Compiling the generated file is a bit large, we can add an optimization parameter:

Go build-ldflags "-s-w"-O hi.out

Try running the binaries.

Finish.
