How to install and use GAS (GNU Compiler) on Linux?
提问by rogcg
I'm using Ubuntu, and I was looking for an assembler compiler for Linux, and I found GAS.
我正在使用 Ubuntu，我正在寻找适用于 Linux 的汇编编译器，我找到了 GAS。
I'm trying to install it and run it, but I can't.
我正在尝试安装并运行它，但我不能。

asis the GNU Assembler. It's found in binutilsbut if you do:
as是GNU 汇编器。它可以在binutils但如果你这样做：
sudo apt-get install build-essential
sudo apt-get install build-essential
You will get gasalong with gcc(which default uses gasfor assembling on the back end).
您将获得gas随gcc（其默认用途gas用于装配在后端）。
For a 'tutorial' about using gas, you probably want to read Programming From the Ground Up, which uses it.
有关使用的“教程” gas，您可能想阅读使用它的编程从头开始。
To build a static executable from a .sfile,
要从文件构建静态可执行.s文件，
#!/bin/bash
f="${1:-}"
as "${f}" -o "${f%%.s}.o" && ld "${f%%.s}.0" -o "${f%%.s}"
gcc -nostdlib -static "${f}" -o "${f%%.s}"
If you want to link with libraries, it's normally easiest to let gcc use the right command line options for asand ldwhen building an executable from an asm source file.gcc foo.s -o foowill work if your foo.sdefines a mainfunction.
如果你想与图书馆联系，这是最简单的，通常让GCC使用正确的命令行选项as，并ld从ASM源文件建立一个可执行文件时。gcc foo.s -o foo如果您foo.s定义了一个main函数，它将起作用。

It's in the binutilspackage.
它在binutils包裹里。

Fire up Synaptic and enter "gnu assembler" into the quick search bar. It's immediately obvious that binutilsis the required package.
启动 Synaptic 并在快速搜索栏中输入“gnu assembler”。很明显，这binutils是必需的包。
And you may well find it's already installed. My binutils 2.20.1-3ubuntu7is already installed and I have a fairly vanilla set-up.
你可能会发现它已经安装了。我binutils 2.20.1-3ubuntu7的已经安装，我有一个相当普通的设置。
Entering as --versionfrom a terminal window will let you know:
as --version从终端窗口输入会让你知道：
