When Make starts, it uses the makefile specified on the command-line or if not specified, then uses the one found by via specific search rules. Generally, Make defaults to using the file in the working directory named Makefile. GNU Make searches for the first file matching: GNUmakefile, makefile, or Makefile.
In DOS, the name is still relative to the root directory of the current disk, so to get a fully qualified file name, the file name must be prefixed with the drive letter and a colon, as in "C:\Users\Name\sample", where "C:" specifies the "C" drive. Also on the above systems, some programs such as the command-line shell will search a path for a ...
The exact definition, giving the criteria for deciding what part of the file name is its extension, belongs to the rules of the specific file system used; usually the extension is the substring which follows the last occurrence, if any, of the dot character (example: txt is the extension of the filename readme.txt, and html the extension of ...
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 .
Ninja is a build system developed by Evan Martin, [4] a Google employee. Ninja has a focus on speed and it differs from other build systems in two major respects: it is designed to have its input files generated by a higher-level build system, and it is designed to run builds as fast as possible.
Hard coding (also hard-coding or hardcoding) is the software development practice of embedding data directly into the source code of a program or other executable object, as opposed to obtaining the data from external sources or generating it at runtime.
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.
A path (or filepath, file path, pathname, or similar) is a string of characters used to uniquely identify a location in a directory structure.It is composed by following the directory tree hierarchy in which components, separated by a delimiting character, represent each directory.
