Preface This article is based on the translation of the first chapter of Autotools-a Practioner's Guide to GNU Autoconf, Automake, and Libtool, omitting some of the statements. Body As the preface says, the GNU Autotools is designed to make life easier for end users, not defenders. Even so, in the long run, using Autotools as a project manager will make your job easier, though it may not be the reason yo

It is primarily compatible with SVR4, although it has some extensions (for example, a macro that handles more than 9 positional parameters). The GNU M4 also has built-in functions to conta

Gnu/linux Powerful and freeWhat is LinuxLinux is a free and open source Unix-like operating system kernel. There are many different Linux distributions that can be installed on a wide variety of computer hardware devices, from phones, tablets, routers and video game consoles, to desktop computers, large computers and supercomputers. Linux is a leading operating system kernel, and the world's fastest 10 supercomputers run on Linux kernel-based operatin

The BSD family and other Linux distributions use "AMD64", the 32-bit version is called "i386" (or i486/586/686), and Arch Linux uses x86_64 to address this 64-bit architecture.Reference:Https://zh.wikipedia.org/wiki/X86Https://zh.wikipedia.org/wiki/X86-64Third, what is LinuxLinux is a free and open source Unix-like operating system.

Of course, this is a historical reason, because Linux since its inception is the 32-bit, is a multi-user multitasking operating system, so the GCC and GNU as a migration to Linux is used to write 32-bit protection mode of code.

GNU Assembler (gas) The GNU assembler (known as gas) is the most popular assembler in the UNIX environment. Unlike most other development packages, the GNU assembler is not published in a separate package. It is bundled with other development software in the GNU Binutils package. The following programs are included in

In all the previous essays in my series, the software was installed and uninstalled using the Linux distribution's own package management tools (such as apt-get, yum, etc.), and never showed you how to use the source code to build the software yourself. But children's shoes, which have long been in the Unix/linux world, know that compiling and installing software from source code is not so difficult, generally three steps:Configure Make Make InstallThe ability to manage the source code is so s

What is GNU? Reference from the official website (http://www.gnu.org/) Definition: GNU is a Unix-like operating system composed of free software. You can choose to install a Linux kernel-based GNU system completely composed of free software. The GNU project was founded in 1984 to develop a complete

The desktop environment version, which was developed over the months, provided a beta version in mid-September, allowing early adopters to be used. One of the most notable aspects of KDE Plasma 5.11 is the introduction of the F

However, in GNU C, there is a very strange usage, that is, an array of length 0, such as array[0]; many people may find it inconceivable that an array of length 0 is meaningless, but here, it represents a completely different layer of meaning, which is not portable, so If you are committed to writing portable, or slightly cross-plat

In addition to the libc and LIBM libraries, there are no other standard naming conventions for UNIX system libraries. Some system libraries on Linux may be different from the names of Libraries on UNIX platforms, which requires knowledge of the features that are included and supported by the various libraries on Linux. Table 3-2 lists some of the Linux system libraries based on the features supported. The following is a list of the library files contained in the
