Make has been implemented numerous times, generally using the same makefile format and providing the same features, but some providing enhancements from the original. Examples: Sun DevPro Make appeared in 1986 with SunOS-3.2. With SunOS-3.2. It was delivered as an optional program; with SunOS-4.0, SunPro Make was made the default Make program.
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 It replaced C11 (standard ISO/IEC 9899:2011), [2] and is superseded by C23 (ISO/IEC 9899:2024) since October 2024.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]
For #include guards to work properly, each guard must test and conditionally set a different preprocessor macro. Therefore, a project using #include guards must work out a coherent naming scheme for its include guards, and make sure its scheme doesn't conflict with that of any third-party headers it uses, or with the names of any globally visible macros.
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]
C++03 is a version of the ISO/IEC 14882 standard for the C++ programming language. It is defined by two standards organizations, the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), in standard ISO/IEC 14882:2003. C++03 replaced the prior C++98 standard. C++03 was later replaced by C++11.
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.
Similarly, a variable CPPFLAGS exists with switches to be passed to the C or C++ preprocessor. Similarly, FFLAGS enables the addition of switches for a Fortran compiler. These variables are most commonly used to specify optimization or debugging switches to a compiler, as for example -g, -O2 or (GCC-specific) -march=athlon.
