Autoconf
GNU Autoconf is a tool for producing configure scripts for building, installing, and packaging software on computer systems where a Bourne shell is available. Autoconf is agnostic about the programming languages used, but it is often used for projects using C, C++, Fortran, Fortran 77, Erlang, or Objective-C. A configure script configures a software package for installation on a particular target system. After running a series of tests on the target system, the configure script generates header files and a makefile from templates, thus customizing the software package for the target system. Together with Automake and Libtool, Autoconf forms the GNU Build System, which comprises several other tools, notably Autoheader. Usage overview The developer specifies the desired behaviour of the configure script by writing a list of instructions in the GNU m4 language in a file called "configure.ac". A library of pre-defined m4 macros is available to describe common configure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

GNU Build System
The GNU Autotools, also known as the GNU Build System, is a suite of programming tools designed to assist in making source code packages portable to many Unix-like systems. It can be difficult to make a software program portable: the C compiler differs from system to system; certain library functions are missing on some systems; header files may have different names. One way to handle this is to write conditional code, with code blocks selected by means of preprocessor directives (#ifdef); but because of the wide variety of build environments this approach quickly becomes unmanageable. Autotools is designed to address this problem more manageably. Autotools is part of the GNU toolchain and is widely used in many free software and open source packages. Its component tools are free software, licensed under the GNU General Public License with special license exceptions permitting its use with proprietary software. The GNU Build System makes it possible to build many programs usin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Configure Script
A configure script is an executable script designed to aid in developing a program to be run on a wide number of different computers. It matches the libraries on the user's computer, with those required by the program before compiling it from its source code. As a common practice, all configure scripts are named configure. Usually, configure scripts are written for the Bourne shell, but they may be written for execution in any desired shell. Usage Obtaining software directly from the source code is a common procedure on Unix computers, and generally involves the following three steps: configuring the makefile, compiling the code, and finally installing the executable to standard locations. A configure script accomplishes the first of these steps. Using configure scripts is an automated method of generating makefiles before compilation to tailor the software to the system on which the executable is to be compiled and run. The final executable software is most commonly obtained ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Automake
In software development, GNU Automake is a programming tool to automate parts of the compilation process. It eases usual compilation problems. For example, it points to needed dependencies. It automatically generates one or more ''Makefile.in'' from files called ''Makefile.am''. Each ''Makefile.am'' contains, among other things, useful variable definitions for the compiled software, such as compiler and linker flags, dependencies and their versions, etc. The generated "''Makefile.in''"s are portable and compliant with the Makefile conventions in the GNU Coding Standards, and may be used by configure scripts to generate a working Makefile. The Free Software Foundation maintains as one of the GNU programs, and as part of the GNU build system. It is used to build several GNU applications and libraries, such as GTK, as well as non-GNU software such as XCircuit. Process Automake aims to allow the programmer to write a makefile in a higher-level language, rather than having t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Makefile
In software development, Make is a build automation tool that automatically builds executable programs and libraries from source code by reading files called ''Makefiles'' which specify how to derive the target program. Though integrated development environments and language-specific compiler features can also be used to manage a build process, Make remains widely used, especially in Unix and Unix-like operating systems. Besides building programs, Make can be used to manage any project where some files must be updated automatically from others whenever the others change. Origin There are now a number of dependency-tracking build utilities, but Make is one of the most widespread, primarily due to its inclusion in Unix, starting with the PWB/UNIX 1.0, which featured a variety of tools targeting software development tasks. It was originally created by Stuart Feldman in April 1976 at Bell Labs. Feldman received the 2003 ACM Software System Award for the authoring of this widesprea ...

GNU Libtool
In computer programming, GNU Libtool is a software development tool, part of the GNU build system, consisting of a shell script created to address the software portability problem when compiling shared libraries from source code. It hides the differences between computing platforms for the commands which compile shared libraries. It provides a commandline interface that is identical across platforms and it executes the platform's native commands. Rationale Different operating systems handle shared libraries differently. Some platforms do not use shared libraries at all. It can be difficult to make a software program portable: the C compiler differs from system to system; certain library functions are missing on some systems; header files may have different names. One way to handle this is to write conditional code, with code blocks selected by means of preprocessor directives (#ifdef); but because of the wide variety of build environments this approach quickly becomes u ...

GNU M4
m4 is a general-purpose macro processor included in most Unix-like operating systems, and is a component of the POSIX standard. The language was designed by Brian Kernighan and Dennis Ritchie for the original versions of UNIX. It is an extension of an earlier macro processor, m3, written by Ritchie for an unknown AP-3 minicomputer.Brian W. Kernighan and Dennis M. Ritchie. The m4 macro processor. Technical report, Bell Laboratories, Murray Hill, New Jersey, USA, 1977pdf/ref> The macro preprocessor operates as a text-replacement tool. It is employed to re-use text templates, typically in computer programming applications, but also in text editing and text-processing applications. Most users require m4 as a dependency of GNU autoconf. History Macro processors became popular when programmers commonly used assembly language. In those early days of programming, programmers noted that much of their programs consisted of repeated text, and they invented simple means for reusing this ...

SCons
SCons is a computer software build tool that automatically analyzes source code file dependencies and operating system adaptation requirements from a software project description and generates final binary executables for installation on the target operating system platform. Its function is analogous to the traditional GNU build system based on the make utility and the autoconf tools. SCons generates project configurations and build process implementations in the form of Python scripts. Major features Major SCons features include the following: * Configuration files are Python scripts, which means that user-written builds have access to a complete general-purpose programming language. * Automatic dependency analysis built-in for C, C++ and Fortran. Dependency analysis is extensible through user-defined dependency scanners for other languages or file types. Unlike the GNU Compiler Collection's (GCC) built-in dependency analysis, it uses a regular expression scan for included ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
System Administrator
A system administrator, or sysadmin, or admin is a person who is responsible for the upkeep, configuration, and reliable operation of computer systems, especially multi-user computers, such as servers. The system administrator seeks to ensure that the uptime, performance, resources, and security of the computers they manage meet the needs of the users, without exceeding a set budget when doing so. To meet these needs, a system administrator may acquire, install, or upgrade computer components and software; provide routine automation; maintain security policies; troubleshoot; train or supervise staff; or offer technical support for projects. Related fields Many organizations staff offer jobs related to system administration. In a larger company, these may all be separate positions within a computer support or Information Services (IS) department. In a smaller group they may be shared by a few sysadmins, or even a single person. * A database administrator (DBA) maintains a d ...

Software Versioning
Software versioning is the process of assigning either unique ''version names'' or unique ''version numbers'' to unique states of computer software. Within a given version number category (e.g., major or minor), these numbers are generally assigned in increasing order and correspond to new developments in the software. At a fine-grained level, revision control is often used for keeping track of incrementally-different versions of information, whether or not this information is computer software. Modern computer software is often tracked using two different software versioning schemes: an ''internal version number'' that may be incremented many times in a single day, such as a revision control number, and a ''release version'' that typically changes far less often, such as semantic versioning or a project code name. History File numbers were used especially in public administration, as well as companies, to uniquely identify files or cases. For computer files this practice was i ...

Free Software Foundation
The Free Software Foundation (FSF) is a 501(c)#501(c)(3), 501(c)(3) non-profit organization founded by Richard Stallman on October 4, 1985, to support the free software movement, with the organization's preference for software being distributed under copyleft ("share alike") terms, such as with its own GNU General Public License. The FSF was incorporated in Boston, Massachusetts, United States, US, where it is also based. From its founding until the mid-1990s, FSF's funds were mostly used to employ software developers to write free software for the GNU Project. Since the mid-1990s, the FSF's employees and volunteers have mostly worked on legal and structural issues for the free software movement and the free software community. Consistent with its goals, the FSF aims to use only free software on its own computers. History The Free Software Foundation was founded in 1985 as a Nonprofit corporation, non-profit corporation supporting free software development. It continued existi ...
