It supports preprocessor directives such as includes and conditional expressions which use variables set on the command-line or within the makefiles. [26] [27] Inference rules differ from Make; for example they can include search paths. [28] Embarcadero make has a command-line option that "Causes MAKE to mimic Microsoft's NMAKE.". [29]
Navigate through the kernel features and menuconfig commands. Esc+Esc: Exit menuconfig or cancel the command. ↵ Enter: Activate a command, or expand a branch. y: Compile and include this feature inside of the kernel. m: Compile this feature as a module, separate from the kernel. n: Do not compile the feature. / Search configuration parameter.
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.
This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.
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 ...
One feature of the Makefile for xv6 is the option to produce a PDF of the entire source code listing in a readable format. The entire printout is only 99 pages, including cross references. [ 2 ] This is reminiscent of the original V6 source code, which was published in a similar form in Lions' Commentary on UNIX 6th Edition, with Source Code .
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 ...
