1. __attribute__ One of the major features of GNU C (which is not known to beginners) is the __attribute__ mechanism. __ATTRIBUTE__ can set function attributes, variable attributes (Variable attribute), and type attributes There are two underscores before and after the __attribute__, followed by a pair of original brackets, with the corresponding __attribute__ parameters inside the brackets. The __ATTRIBUTE__ syntax format is: __attribute__ ((att

Writing makefile by hand is a very interesting thing, and for larger projects, it is a good thing if there are tools to do it. In the Linux system development environment, the GNU Autotools undoubtedly played this important role. (In a Windows system development environment, IDE tools, such as visual Studio, are also handy for managing projects.) )This article takes a simple project as an example to illustrate the use of a list of the

What is GNU In GNU/Linux? GNU is a technical organization, the GNU program, also known as the genu program.

The recent GPU acceleration of an algorithm, found to actually use GCC's-o3 (the highest-level compilation optimization) option, can achieve a high acceleration ratio, my program has reached 3 times times, and sometimes the effect is even better than the GPU acceleration. So a little learning about the GNU compiler optimization. PostScript a sentence, when debugging, it is best to turn off the compilation optimization, otherwise the program automatica

GnuPG is designed in accordance with the OPENPGP technical standard set by the IETF. GnuPG for encryption, digital signature and the creation of asymmetric key pairs of software. GnuPG is part of the GNU program of the Free Software Foundation and is currently funded by the German government. Authorized under the

What is Linux? Linux is a free and open source UNIX-like operating system kernel. There are currently many different Linux releases that can be installed on a variety of computer hardware devices, from mobile phones, tablets, routers and audio and video game consoles to desktop computers, large Computer and super computer. Linux is a leading operating system kernel. The world's top 10 super computers run Linux kernel-based operating systems. The Linux operating system is also the most famous exa

Click here to share it with you! The available C compiler on Linux is the gnu c compiler, which is based on the programming license of the Free Software Foundation and can be freely released. Gnu c has made a series of extensions for Standard C to enhance the functions of Standard C.1. Zero-length ArrayGnu c allows zero-length arrays. This feature is particularly useful when defining the header structure of

Development Environment In GNU/Linux In the work environment, virtual machines are a major issue. Therefore, we will introduce them separately before this chapter. In addition to virtual machines, there are several important things, including the editor, compiler, and the automation tool GNU make.Many working in Linux use VI or Emacs as the editor. If you are interested in trying, I suggest you do not give

With the development of the Internet over the years, WEB Log statistics tools have become more and more mature and feature-rich. Many of them are open source code, and AWStats is an excellent one.AWStats: Advanced Web Statistics AWStats is a fast-growing Perl-based WEB log analysis tool on Sourceforge. Compared With Webalizer, an excellent open-source log analysis tool, AWStats has the followin

The support and developers of the GNU program, especially Richard Stallman, refer to a Unix-like operating system called Linux as GNU/Linux. Linux is not a complete operating system, but a Unix-like kernel. It was developed by Linus Torvalds and others. The first version was released in 1991. The GNU program started in 1984 with the goal of completing a comple
