Go language hello. Go

Preface

The running environment is in Ubuntu. Follow the instructions on the official website for simple installation. This is not detailed here. There is no error in installation errors. Next I will write a hello. Go file based on the simple website.

CodeAs follows:

 

Package main

Import "FMT"

Func main (){

FMT. printf ("Hello, world ")

}

Run the following command:

6g hello. Go

6l hello.6

./6.out

 

Output result: Hello, world

 

Run the command to generate a 64-bit exe Program:

6l-O hello.exe hello.6

The size of the generated file is 1.1 MB. the following error is reported when the file is run in window 7 32 bits:

Program too big to fit memory.

 

The following describes how to generate 32 programs in a 64-bit operating system.

 

After finding the code, I haven't found it for a long time. However, in addition to 6 GB, gccgo can also be compiled, and the generated code is more efficient.
