GCC编译工具链（更新中）

GCC编译工具链是围绕GCC编译器构建的一套开发工具，用于将源代码转化为可执行程序，源码主要包括GCC编译器、源码Binutils工具集和glibc库。源码云录播源码GCC作为一款强大的源码多语言编译器，最初支持C语言，源码后来扩展到C++、源码Fortran和Java等，源码其性能优秀，源码效率比一般编译器高%~%。源码官方网站：gcc.gnu.org。源码android 源码打开

Ubuntu系统内置了GCC编译器，源码可通过命令查看版本和路径。源码Binutils是源码GNU二进制工具集，与GCC一起安装，源码常用工具如readelf。猎管家源码glibc是C语言的标准库，对程序运行至关重要，如read、write等函数，Ubuntu系统中的php 直播源码glibc版本可通过命令查看，学习时可研究其源代码，官网地址为The GNU C Library。

要安装ARM-GCC，有三种方式，包括使用APT安装、linux stat源码第三方Linaro工具链或直接编译。交叉编译是指在一种架构的系统上为另一种架构生成代码，例如，使用arm-linux-gnueabihf-gcc编译Hello World程序。交叉编译的流程与本地编译相似，主要区别在于编译工具，生成的可执行文件适用于特定的ARM平台，如使用readelf工具分析其结构。

在编译过程中，创建一个名为helloworld.c的文件，编写代码并执行交叉编译命令，最终生成的helloworld是ARM平台的可执行文件。readelf工具随GCC工具链安装，用于查看程序详细信息。
