How to install and use gcc in golang

Golang is an open source programming language. Its emergence gives developers powerful tools and flexibility, thereby improving product quality and efficiency. During development using Golang, you may need to use the gcc tool. In this article, we will learn how to install gcc and use gcc in Golang.

1. Install gcc

gcc is a collection of compilers developed by the GNU (GNU's Not Unix) open source organization. It mainly supports programming languages ​​​​such as C, C and Fortran. gcc is a part of Golang that makes Golang compilation faster and more efficient.

Before installing gcc, we need to ensure that Golang has been correctly installed and configured on the system. You can check the installation status of Golang through the following command:

$ go version

The method of installing gcc is also very simple. Just execute the following command:

$ sudo apt-get update
$ sudo apt-get install build-essential

This command will install the basic environment of gcc. If If you want to install a specific gcc version, you need to use the following command:

$ sudo apt-get install gcc-4.8

2. Use gcc to compile the Golang project

Before using gcc to compile the Golang project, we need to use the go build command to compile A binary executable file of Golang code. In the root directory of the current golang project, use the following command to compile:

$ go build

This command will generate a binary executable file named main, which can be used directly on the system.

Next, we can pass the executable file to the gcc tool for compilation. For example, assuming we want to compile this file into an executable file on the Windows platform, we can use the following command:

$ env CGO_ENABLED=1 CC=x86_64-w64-mingw32-gcc GOARCH=amd64 GOOS=windows go build -ldflags "-s -w" -o app_windows.exe

This command will use the x86_64-w64-mingw32-gcc compiler to generate an executable file for the Windows platform. Execute the file and name it app_windows.exe.

3. Conclusion

Through this article, we learned how to install gcc in the Golang project and how to use gcc to compile the Golang project. In actual development, using gcc to compile Golang code can greatly improve compilation speed and portability, so mastering these skills will be very helpful to our development work.
