在为 Linux 开发应用程序时，绝大多数情况下使用的都是 C 语言，因此几乎每一位 Linux程序员面临的首要问题都是如何灵活运用 C 编译器。目前 Linux 下最常用的C 语言编译器是 GCC（GNU Compiler Collection），它是 GNU项目中符合 ANSI C 标准的编译系统，能够编译用C、C++和Object C 等语言编写的程序。GCC 不仅功能非常强大，结构也异常灵活。最值得称道的一点就是它可以通过不同的前端模块来支持各种语言，如 Java、 Fort ran、Pascal、Modula-3和 Ada等。 -In developing applications for Linux, the vast majority of cases are used in C language, so almost every Linux programmer facing a primary problems are how to make flexible use of C compiler. Linux is currently the most commonly used C language compiler is a GCC (GNU Compiler Collection), it is the GNU project in line with the standard ANSI C compiler system, able to compile with C, C++ And Object C language, such as procedures. GCC is not only very powerful, flexible structure is also abnormal. The most commendable is that it can through a variety of front-end module to support a variety of languages such as Java, Fort ran, Pascal, Modula-3 and Ada, etc..
