For example, the macro CC is frequently used in makefiles to refer to the location of a C compiler. If used consistently throughout the makefile, then the compiler used can be changed by changing the value of the macro rather than changing each rule command that invokes the compiler. Macros are commonly named in all-caps:
Boost boost.build – For C++ projects, cross-platform, based on Perforce Jam; Buck – Build system developed and used by Meta Platforms; written in Rust, using Starlark (BUILD file syntax) as Bazel; Buildout – programming tool aimed to assist with deploying software; Python-based
makedepend solves this problem by parsing the code of C source files to generate a list of dependencies (those header files included directly and indirectly). It is able to understand conditional compilation constructs so as to not generate excessive dependencies. It then appends rules expressing the dependencies to the Makefile.
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. [ 2 ] The Free Software Foundation maintains automake as one of the GNU programs, and as part of the GNU build system .
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 ...
Support automatic dependency scanning of C/C++ header files; All features must work consistently and equally well on all supported platforms; For various reasons, CMake developers chose to develop a scripting language for CMake instead of using Tcl – a popular language for building at the time. Use of Tcl would have then added a dependency to ...
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 .
OpenPorts.se, originally announced as ports.openbsd.nu in 2006, [9] was a custom-written web-site that does its own parsing of the ports tree structure and the updates, and has the functionality of tracking changes of a given port, having a shortcoming of not supporting some of the more complicated Makefile logic, and thus missing some 15% of ...
