What is the use of SCons?

What is the use of SCons?

SCons is a computer software build tool that automatically analyzes source code file dependencies and operating system adaptation requirements from a software project description and generates final binary executables for installation on the target operating system platform.

How use SCons command line?

SCons has many command-line options that control its behavior. A SCons command-line option always begins with one or two – (hyphen) characters….12.1. 4. Strings for Getting or Setting Values of SCons Command-Line Options.

String for GetOption and SetOption	Command-Line Option(s)
diskcheck	–diskcheck

What compiler does SCons use?

So the above example would tell SCons to explicitly configure the default environment to use its normal GNU Compiler and GNU Linker settings (without having to search for them, or any other utilities for that matter), and specifically to use the compiler found at /usr/local/bin/gcc.

What is SCons Makefile?

SCons is an open source build system written in the Python language, similar to GNU Make. It uses a different approach than the usual Makefile, but instead uses SConstruct and SConscript files instead.

Is SCons dead?

Scons is effectively dead, and I wish people would start removing it from the Python build systems web pages. Meson is written in Python and isn’t dead. However, Meson requires a partner to actually build things–something like cmake or ninja.

What is SCons command?

as a command-line target: scons . Building all target files, including any files outside of the current directory, may be specified by supplying a command-line target of the root directory (on POSIX systems): scons / or the path name(s) of the volume(s) in which all the targets should be built (on Windows systems):

What is SCons Linux?

SCons is an Open Source software construction tool. Think of SCons as an improved, cross-platform substitute for the classic Make utility with integrated functionality similar to autoconf/automake and compiler caches such as ccache. In short, SCons is an easier, more reliable and faster way to build software.

How do you check if SCons is installed?

4 Answers

1. Install python, including pip and tick ‘add python to PATH’
2. Run pip install scons in command line.
3. If you run pip show scons it’ll show you where the Scons code actually is (for me it’s c:serssername\appdata\roaming\python\python38\site-packages – but this is not what you want to add to your path.

How do you clean SCons?

When using SCons, it is unnecessary to add special commands or target names to clean up after a build. Instead, you simply use the -c or –clean option when you invoke SCons, and SCons removes the appropriate built files.

Where is SCons located?

The reason is because scons. bat is in C:\Python38 and scons.py is in C:\Python38\Scripts . To run scons, it needs to find scons.

How do you use target in makefile?

How does it work?

1. When you type make or make [target] , the Make will look through your current directory for a Makefile.
2. Make will then look for the corresponding target in the makefile.
3. If the target is found, the target’s dependencies will be run as needed, then the target commands will be run.

How do I set a default target in makefile?

If the first rule in the makefile has several targets, only the first target in the rule becomes the default goal, not the whole list. You can manage the selection of the default goal from within your makefile using the . DEFAULT_GOAL variable (see Other Special Variables).

Is buck based on Bazel?

Buck Build System Buck is a build system created by Facebook especially for supporting monorepos. Like Bazel, it’s open source and declarative. It supports multiple programming languages across many platforms, like iOS, Android, and .

Is Bazel better than Gradle?

In summary, the data and analysis indicates clearly that Gradle is a better choice than Bazel for most JVM projects. We will provide an equivalent comparison for Android projects in a follow up article.

What are targets in makefile?

A simple makefile consists of “rules” with the following shape: target … : prerequisites … recipe … … A target is usually the name of a file that is generated by a program; examples of targets are executable or object files. A target can also be the name of an action to carry out, such as ‘ clean ‘ (see Phony Targets).

What is a target and a rule in makefile?

A rule appears in the makefile and says when and how to remake certain files, called the rule’s targets (most often only one per rule). It lists the other files that are the prerequisites of the target, and the recipe to use to create or update the target.

Why is Bazel fast?

Bazel may give you faster build times because it can recompile only the files that need to be recompiled. Similarly, it can skip re-running tests that it knows haven’t changed.
