Libtool
GNU Libtool is a software development tool, part of the GNU build system, consisting of a shell script created to address the Software_portability#Effort_to_port_source_code, software portability problem when Compiler, compiling Shared_library#Shared_libraries, shared libraries from source code. It Abstraction_(computer_science), hides the differences between Computing platform, computing platforms for the commands which compile shared libraries. It provides a command-line interface that is identical across platforms and it executes the platform's Native_(computing)#Applications, native commands, allowing software authors to offer build support for their code across many diverse platforms such as Linux, BSD variants, Windows (via Cygwin), HP-UX, Oracle Solaris, Solaris (including on SPARC processors), AIX, and IRIX. Rationale Different operating systems handle shared library, shared libraries differently. Some platforms do not use shared libraries at all. It can be difficult ...

GNU Build System
The GNU Autotools, also known as the GNU Build System, is a suite of build automation tools designed to support building source code and packaging the resulting binaries. It supports building a codebase for multiple target systems without customizing or modifying the code. It is available on many Linux distributions and Unix-like environments. 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. Motivation It can be difficult to make a software program portable. Compilers differ from system to system. Certain library functions are missing on some systems. Compiler files (such as C headers) may have different names. Shared libraries may be compiled and installed in different ways. One way to handle platform differences is to write conditionally compiled code (i. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shared Library
In computing, a library is a collection of System resource, resources that can be leveraged during software development to implement a computer program. Commonly, a library consists of executable code such as compiled function (computer science), functions and Class (computer programming), classes, or a library can be a collection of source code. A resource library may contain data such as images and Text string, text. A library can be used by multiple, independent consumers (programs and other libraries). This differs from resources defined in a program which can usually only be used by that program. When a consumer uses a library resource, it gains the value of the library without having to implement it itself. Libraries encourage software reuse in a Modular programming, modular fashion. Libraries can use other libraries resulting in a hierarchy of libraries in a program. When writing code that uses a library, a programmer only needs to know how to use it not its internal d ...

Autoconf
GNU Autoconf is a software development tool for generating a configure script that in turn generates files for building a codebase and for packaging or installing the resulting files. Autoconf is part of the GNU Build System along with Automake, Libtool, Autoheader and other tools. Autoconf is agnostic about the programming language of the codebase to build. None-the-less, it is primarily used with C, C++, Fortran, 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. 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 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oracle Solaris
Oracle Solaris is a proprietary Unix operating system offered by Oracle for SPARC and x86-64 based workstations and servers. Originally developed by Sun Microsystems as Solaris, it superseded the company's earlier SunOS in 1993 and became known for its scalability, especially on SPARC systems, and for originating many innovative features such as DTrace, ZFS and Time Slider. After the Sun acquisition by Oracle in 2010, it was renamed Oracle Solaris. Solaris was registered as compliant with the Single UNIX Specification until April 29, 2019. Historically, Solaris was developed as proprietary software. In June 2005, Sun Microsystems released most of the codebase under the CDDL license, and founded the OpenSolaris open-source project. Sun aimed to build a developer and user community with OpenSolaris; after the Oracle acquisition in 2010, the OpenSolaris distribution was discontinued and later Oracle discontinued providing public updates to the source code of the Solaris kernel, ...

IRIX
IRIX (, ) is a discontinued operating system developed by Silicon Graphics (SGI) to run on the company's proprietary MIPS architecture, MIPS workstations and servers. It is based on UNIX System V with Berkeley Software Distribution, BSD extensions. In IRIX, SGI originated the XFS file system and the industry-standard OpenGL graphics API. History SGI originated the IRIX name in the 1988 release 3.0 of the operating system for the SGI IRIS 4D series of workstations and servers. Previous releases are identified only by the release number prefixed by "4D1-", such as "4D1-2.2". The "4D1-" prefix continued to be used in official documentation to prefix IRIX release numbers. Prior to the IRIS 4D, SGI bundled the GL2 operating system, based on UniSoft UniPlus System V Unix, and using the proprietary MEX (windowing system), MEX (Multiple EXposure) windowing system. IRIX 3.x is based on UNIX System V Release 3 with 4.3BSD enhancements, and incorporates the 4Sight windowing system, based o ...

Operating System
An operating system (OS) is system software that manages computer hardware and software resources, and provides common daemon (computing), services for computer programs. Time-sharing operating systems scheduler (computing), schedule tasks for efficient use of the system and may also include accounting software for cost allocation of Scheduling (computing), processor time, mass storage, peripherals, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computerfrom cellular phones and video game consoles to web servers and supercomputers. , Android (operating system), Android is the most popular operating system with a 46% market share, followed ...

Dynamic Library
A dynamic library is a library that contains functions and data that can be consumed by a computer program at run-time as loaded from a file separate from the program executable. Dynamic linking or late binding allows for using a dynamic library by linking program library references with the associated objects in the library either at load-time or run-time. At program build-time, the linker records what library objects the program uses. When the program is run, a ''dynamic linker'' or ''linking loader'' associates program library references with the associated objects in the library. A dynamic library can be linked at build-time to a stub for each library resource that is resolved at run-time. Alternatively, a dynamic library can be loaded without linking to stubs. Most modern operating systems use the same format for both a dynamic library and an executableSome older systems, e.g., Burroughs MCP, Multics, also have a single format which affords two main advantages: it nec ...
