A new SCons release, 3.0.3, is now available on the SCons download page:
https://scons.org/pages/download.html
Here is a summary of the changes since 3.0.1:
NEW FUNCTIONALITY
- Properly support versioned shared libraries for MacOS. We've also introduced two
new env variables APPLELINK_CURRENT_VERSION and APPLELINK_COMPATIBILITY_VERSION which will specify
what is passed to the linkers -current_version and -compatibility_version flags. If not specified
they will be derived from SHLIBVERSION as such:
- APPLELINK_CURRENT_VERSION = SHLIBVERSION
- APPLELINK_COMPATIBILITY_VERSION = all but the last digit in SHLIBVERSION with .0 appended.
Note that the values of the above will be validated. Valid format for either APPLELINK variable is
X[.Y[.Z]] where 0 <= X <= 65535, 0 <= Y <= 255, 0 <= Z <= 255.
- Add flag must_exist to SConscript() call to fail on missing script.
Not failing on missing script is now considered deprecated, and the first instance will print a
deprecation message.
- Add xz compression format to packaging choices.
- Add Textfile/Substfile to default environment. (issue #3147)
- Added virtualenv support. A new function Virtualenv() determines whether
SCons runs in a virtualenv. The search PATH may also be extended to
prefer executables from the current virtualenv over the ones provided by
base environment. New option --enable-virtualenv provided to import some
virtualenv-related variables to SCons and extend every env['ENV']['PATH']
automatically. New option --ignore-virtualenv disables this. Two
environment variables, SCONS_ENABLE_VIRTUALENV and
SCONS_IGNORE_VIRTUALENV are supported for the same purpose.
DEPRECATED FUNCTIONALITY
- Going forward calling SConscript on a non-existing SConscript file will issue a warning. Currently
it will issue a deprecation notice.
CHANGED/ENHANCED EXISTING FUNCTIONALITY
- Recognize new java 9, 10, 11 (as 9.0 and 10.0, 11.0)
DOCUMENTATION
- Update some doc examples for Py3: map() now returns an iterable
instead of a list.
FIXES
- Fix issue #2980 with credit to Piotr Bartosik (and William Blevins). This is an issue where using
TimeStamp-MD5 Decider and CacheDir can yield incorrect md5's being written into the .sconsign.
The difference between Piotr Bartosik's patch and the current code is that the more complicated
creation of file to csig map is only done when the count of children for the current node doesn't
match the previous count which is loaded from the sconsign.
Thanks to Bernard Blackham, William Deegan, Ray Donnelly, Andrew Featherstone, Arda Fu,
Philipp Maierhöfer, Matthew Marinets, Fredrik Medley, Daniel Moody, Gary Oberbrunner,
