In the command lines of suffix rules, POSIX specifies [50] that the internal macro $< refers to the first prerequisite and $@ refers to the target. In this example, which converts any HTML file into text, the shell redirection token > is part of the command line, whereas $< is a macro referring to the HTML file:
After navigating a command-line shell to the directory that contains the source code, the following commands are typically executed: [1] ./configure make make install For the Autotools, the configure script logs status and errors to file config.log , and the command ./configure --help outputs command line help information.
Compared to Make, Ant uses less platform-specific shell commands. Ant provides built-in functionality that is designed to behave the same on all platforms. For example, in the sample build.xml file above, the clean target deletes the classes directory and everything in it. In a Makefile this would typically be done with the command: rm -rf classes/
The configure script, when run, scans the build environment and generates a subordinate config.status script which, in turn, converts other input files and most commonly Makefile.in into output files (Makefile), which are appropriate for that build environment. Finally, the make program uses Makefile to generate executable programs from source ...
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.
makedepend is invoked with a list of sourcefiles: . makedepend [options] foo.c bar.c ... However, it is more often invoked as a target from a makefile, typically under the depend target, such that make depend will invoke makedepend on all source files in the project.
A programming tool that produces portable makefiles for use by the make program, used in compiling software. GNU GPL: Bash: A free software Unix shell written for the GNU Project: GNU GPL: bc: bc is a basic calculator (often referred to as bench calculator), is "an arbitrary precision calculator language" with syntax similar to the C ...
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.
