The distutils package was not shipped as a standard part of +Python until Python version 1.6, so if your system is running Python +1.5.2, you may not have distutils installed. If you are running +Python version 1.6 or later, you should be fine. + +NOTE TO RED HAT USERS: Red Hat shipped Python 1.5.2 as the default all +the way up to Red Hat Linux 7.3, so you probably do *not* have distutils +installed, unless you have already done so manually or are running Red +Hat 8.0 or later. + +In this case, your options are: + + -- (Recommended.) Install from a pre-packaged SCons package that + does not require distutils: + + Red Hat Linux scons-0.97-1.noarch.rpm + + Debian GNU/Linux scons_0.97-1_all.deb + (or use apt-get) + + Windows scons-0.97.win32.exe + + -- (Optional.) Download the latest distutils package from the + following URL: + + http://www.python.org/sigs/distutils-sig/download.html + + Install the distutils according to the instructions on the page. + You can then proceed to the next section to install SCons from + this package. + + INSTALLATION ============ -Installation of this package should be as simple as unpacking the -archive (either .tar.gz or .zip) in any directory (top-level or a -subdirectory) within the software package with which you want to ship -SCons. +Assuming your system satisfies the installation requirements in the +previous section, install SCons from this package simply by running the +provided Python-standard setup script as follows: -Once you have installed this package, you should write an SConstruct -file at the top level of your source tree to build your software as you -see fit. + # python setup.py install -Then modify the build/install instructions for your package to instruct -your users to execute SCons as follows (if you installed this package in -your top-level directory): +By default, the above command will do the following: - $ python scons.py + -- Install the version-numbered "scons-0.97" and "sconsign-0.97" + scripts in the default system script directory (/usr/bin or + C:\Python*\Scripts, for example). This can be disabled by + specifying the "--no-version-script" option on the command + line. -Or (if, for example, you installed this package in a subdirectory named -"scons"): + -- Install scripts named "scons" and "sconsign" scripts in the + default system script directory (/usr/bin or C:\Python*\Scripts, + for example). This can be disabled by specifying the + "--no-scons-script" option on the command line, which is useful + if you want to install and experiment with a new version before + making it the default on your system. - $ python scons/scons.py + On UNIX or Linux systems, you can have the "scons" and "sconsign" + scripts be hard links or symbolic links to the "scons-0.97" and + "sconsign-0.97" scripts by specifying the "--hardlink-scons" + or "--symlink-scons" options on the command line. -That should be all you have to do. (If it isn't that simple, please let -us know!) + -- Install "scons-0.97.bat" and "scons.bat" wrapper scripts in the + Python prefix directory on Windows (C:\Python*, for example). + This can be disabled by specifying the "--no-install-bat" option + on the command line. + On UNIX or Linux systems, the "--install-bat" option may be + specified to have "scons-0.97.bat" and "scons.bat" files + installed in the default system script directory, which is useful + if you want to install SCons in a shared file system directory + that can be used to execute SCons from both UNIX/Linux and + Windows systems. -CONTENTS OF THIS PACKAGE -======================== + -- Install the SCons build engine (a Python module) in an + appropriate version-numbered SCons library directory + (/usr/lib/scons-0.97 or C:\Python*\scons-0.97, for example). + See below for more options related to installing the build + engine library. -This scons-local package consists of the following: + -- Install the troff-format man pages in an appropriate directory + on UNIX or Linux systems (/usr/share/man/man1 or /usr/man/man1, + for example).

The script sets up the Python - sys.path variable to use the build engine found in the - scons-local-{version}/ directory in preference to any other - SCons build engine installed on your system. + # python setup.py install --standalone-lib + +This is usually not recommended, however. + +Note that, to install SCons in any of the above system directories, +you should have system installation privileges (that is, "root" or +"Administrator") when running the setup.py script.
