SCons is a software construction tool (build tool, or make tool) written in Python. It is based on the design which won the Software Carpentry build tool competition in August 2000. Version 0.13 of SCons has been released and is available for download from the SCons web site: http://www.scons.org/ Or through the download link at the SCons project page at SourceForge: http://sourceforge.net/projects/scons/ RPM and Debian packages and a Win32 installer are all available, in addition to the traditional .tar.gz and .zip files. WHAT'S NEW IN THIS RELEASE? Release 0.13 contains an important fix for a critical bug found shortly after SCons version 0.12 was released. SCons version 0.12 has a bug that occurs when a build directory is used without duplicating source files in the build tree ("BuildDir(duplicate=0)") and any subsidiary SConscript file includes another SConscript file. This bug has been fixed in version 0.13, and a test has been added to the regression test base to catch this situation in the future. Release 0.13 also contains an unrelated fix to support fetching files using earlier versions of Perforce that don't use the Windows registry. ABOUT SCONS Distinctive features of SCons include: - a global view of all dependencies; no multiple passes to get everything built properly - configuration files are Python scripts, allowing the full use of a real scripting language to solve difficult build problems - a modular architecture allows the SCons Build Engine to be embedded in other Python software - the ability to scan files for implicit dependencies (#include files); - improved parallel build (-j) support that provides consistent build speedup regardless of source tree layout - use of MD5 signatures to decide if a file has really changed; no need to "touch" files to fool make that something is up-to-date - easily extensible through user-defined Builder and Scanner objects - build actions can be Python code, as well as external commands An scons-users mailing list is available for those interested in getting started using SCons.
