From the + start, &SCons; has made clean installation a priority. + + + +
+ Version Control + + + + Distributing an application like &SCons; that depends + on a package normally found in a library poses a + problem. If the &scons; script and the &SCons; Build Engine + are installed separately, it could be easy + to introduce a version mismatch between the Build Engine + installed in + /usr/lib/python*/site-packages + and the &scons; script installed in + /usr/bin. + Such a mismatch + could possible mean exceptions that prevent builds, or even worse, + silently unreliable builds. + + + + + + To reduce the possibility of a version mismatch, + the &scons; script looks first for its + imported modules in /usr/lib/scons-{version}/, + then in /usr/lib/scons/, + and then in the normal &PYTHONPATH; locations, + including /usr/lib/python*/site-packages). + Searching in a version-specific library directory first + makes it convenient to install and use multiple + side-by-side versions of &SCons;, + which is sometimes important + when verifying that a new version does not introduce any + errors into the local build process. + Searching next in an &SCons;-specific library directory + makes it convenient for other software to find + the &SCons; Build Engine without having to worry about + installing separate copies for + multiple versions of Python. + + + +
+ +
+ Packages + + + + &SCons; is currently distributed in the following packages: + + + + + + + + + + + scons-version.tar.gz + + + + The traditional .tar.gz file, + installable by running setup.py. + + + + + + + scons-version.noarch.rpm + + + + An RPM file for typical installation. + + + + + + + scons-version_all.deb + + + + A Debian package. + + + + + + + scons-version.win32.exe + + + + A Windows installer. + + + + + + + scons-version.src.rpm + + + + A source RPM file. + + + + + + + scons-src-version.tar.gz + + + + A tarball of the &SCons; source tree, + including the full set of regression tests. + + + + + + +
+ + + + Like other software written in Python, &SCons; benefits greatly from + the tremendous effort put into the distutils by + Greg Ward and others. These take care of 90% of the work by making + it almost trivial to generate the appropriate RPM files, Debian + packages, and Windows installer. + + + +
+ +
+ Default Builder Objects + + + + As part of the installation process, &SCons; runs a set of scripts + that look for popular compilers and other tools and set up + appropriate default &Builder; objects for the tools found. These + &Builder; objects are then used to initialize the default &consenv; + values. + + + +
+ +
+ Default Scanner Objects + + + + Additionally, &SCons; comes with a stock set of &Scanner; objects + for the various file types that it supports out of the box. Any + unusal &Scanner; objects required for a specific tool will be + detected at installation time and associated with the appropriate + &Builder; object for the tool. + + + +
