- Removed a lot of compatibility methods and workarounds for Python versions < 2.7, in order to prepare the work towards a combined 2.7/3.x version. Also fixed the default arguments for the print_tree and render_tree methods. - Added support for cross-language dependency scanning; SCons now respects scanner keys for implicit dependencies. - Notes for SCons users with heterogeneous systems. - May find new (previously missed) dependencies. - May cause rebuild after upgrade due to dependency changes. - May find new dependency errors (EG. cycles). - Discovered in some of the SCons QT tests. - Resolved missing cross-language dependencies for SWIG bindings - Corrected typo in User Guide for Scanner keyword. - Install builder interacts with scanner found in SCANNERS differently. - Previous: Install builder recursively scanned implicit dependencies for scanners from SCANNER, but not for built-in (default) scanners. - Current: Install builder will not scan for implicit dependencies via either scanner source. This optimizes some Install builder behavior and brings orthogonality to Install builder scanning behavior. - Add better messaging when two environments have different actions for the same target - Fix issue only with MSVC and Always build where targets marked AlwaysBuild wouldn't make it into CHANGED_SOURCES and thus yield an empty compile command line. - Fix posix platform escaping logic to properly handle paths with parens in them "()". - Intel Compiler 2016 (Linux/Mac) update for tool directories. - Fix for issue 2494: Added string support for Chmod function. - change cache to use 2 character subdirectories, rather than one character, so as not to give huge directories for large caches, a situation which causes issues for NFS. For existing caches, you will need to run the scons-configure-cache.py script to update them to the new format. You will get a warning every time you build until you co this. - Fix a bunch of unit tests on windows |
