Compile a simple C program The typical example of C language isHello WorldThe following is an example of code: #include Assume that the code is saved as the file 'hello. C '. To useGccCompile the file and run the following command: $ Gcc-g-wall hello. C-O hello This command compiles the code in the file 'hello. c' into a machine code and stores it in the executable file 'Hello. The file name of the machine code is-OOption. This option is usually u

Uncommon but useful GCC command line options (2)GuideThe gcc compiler provides a list of almost countless command line options. Of course, no one has ever used or mastered all of its command line options, but there are some command line options that every gcc user should know-even if not required. Some of them are very common, others are not very common, but they

Less Optimization-> more optimization: O0 --> O1 --> O2 --> O3 -O0 indicates no optimization,-O1 indicates the default value, and-O3 indicates the highest optimization level. English explanation: '-O''-O1'Optimize. Optimizing compilation takes somewhat more time, andLot more memory for a large function.With '-O', the compiler tries to reduce code size and executionTime, without specify Ming any optimizations that take a great dealOf Compilation Time.'-O' turns on the following optimization flag

GCC optionsGCC has more than 100 compilation options available. many of these options may never be used, but some of the main options will be frequently used. many GCC options include more than one character. therefore, you must specify the respective characters for each option, and, just like most Linux commands, you cannot separate the characters with a group of options. for example, the following two com

Introduction to GCC applications in Linux-general Linux technology-Linux programming and kernel information. The following is a detailed description. When developing applications for Linux, the C language is used in most cases. Therefore, almost every Linux programmer is faced with the primary issue of flexible use of the C compiler. Currently, the most common C language Compiler in Linux is GCC (GNU Compil

I. StatementAlthough most of Linux's core code is written in C language, some of them are inevitably written in assembly language. Some assembly language code is directly written in the Assembly source program, especially the Linux Startup code. Others are embedded in the C language program using the GCC embedded assembly language. This article briefly introduces the Embedded Assembly Language in GCC. It ma

Introduction to GCC 1. GCC is the abbreviation of GNU Compiler Collection. Originally, it was a C language compiler (gnu c compiler). The author was Richard Stallman and was the founder of the GNU project. Now it supports multiple languages, such as C, C ++, Java, Pascal, Ada, and Cobol. 2. Main features: GCC is a portable compiler that supports multiple

One, GNUGNU is the "GNU's not Unix" recursive abbreviation, Stallman announced that GNU should pronounce Guh-noo (slave) to avoid confusion with the word new (note: GNU in English is intended to be the African wildebeest, the same pronunciation as new)In order to ensure that GNU software is free to "use, reproduce, modify and distribute", all GNU software is licensed under the terms of an agreement that authorizes all rights to anyone without the addition of any restrictions to any other person,
