Make's dependency ordering and out-of-date checking makes the build process more robust and more efficient. The makefile allowed for better organization of build logic and often fewer build files. Make is widely used in part due to its early inclusion in Unix, starting with PWB/UNIX 1.0, which featured a variety of software development tools. [3]
Version 3.0 was released in June 2014. [8] It has been described as the beginning of "Modern CMake". [9] Experts now advise to avoid variables in favor of targets and properties. [10] The commands add_compile_options, include_directories, link_directories, link_libraries that were at the core of CMake 2 should now be replaced by target-specific ...
C17, formally ISO/IEC 9899:2018, [1] is an open standard for the C programming language, prepared in 2017 and published in July 2018. It replaced C11 (standard ISO/IEC 9899:2011), [2] and is superseded by C23 (ISO/IEC 9899:2024) since October 2024. [3]
The C programming language provides many standard library functions for file input and output.These functions make up the bulk of the C standard library header <stdio.h>. [1] The functionality descends from a "portable I/O package" written by Mike Lesk at Bell Labs in the early 1970s, [2] and officially became part of the Unix operating system in Version 7.
If they are not specified in the Makefile, then they will be read from the environment, if present. Tools like autoconf's ./configure script will usually pick them up from the environment and write them into the generated Makefiles. Some package install scripts, like SDL, allow CFLAGS settings to override their normal settings (instead of ...
In that time period, the C++17 revision was also called C++1z, following C++0x or C++1x for C++11 and C++1y for C++14. The C++17 specification reached the Draft International Standard (DIS) stage in March 2017. [1] [2] This DIS was unanimously approved, with only editorial comments, [3] and the final standard was published in December 2017. [4]
Automake is written in Perl and must be used with GNU Autoconf. [2] Automake contains the following commands: aclocal; automake; aclocal, however, is a general-purpose program that can be useful to autoconf users. The GNU Compiler Collection (GCC), for example, uses aclocal even though its makefile is hand written.
The C++ Standard Library provides several generic containers, functions to use and manipulate these containers, function objects, generic strings and streams (including interactive and file I/O), support for some language features, and functions for common tasks such as finding the square root of a number.
