[Scons-users] Using Python 2.5

[Rob Boehne]

Yes, it is.

Running with newer pythons give me errors like this:


TypeError: sequence item 0: expected string, _ListOption found:

  File "/Volumes/Development/apdfl-sandbox/DLE/SConstruct", line 1556:

    env.Append(DOXYLANGLIST=' '.join(env.get('LANGLIST')))

Build completed with status 2

And this:


TypeError: unhashable type: 'NodeList':

  File "/Volumes/Development/apdfl-sandbox/DLE/SConstruct", line 1730:

    libraries = swigenv.SConscript('SWIG.scons', exports={'env': swigenv}, build_dir="$BUILDDIR", duplicate=0)

  File "/Volumes/Development/apdfl-sandbox/python2.6-env-robs-mbp/lib/python2.6/site-packages/scons-0.97p5-py2.6.egg/scons-0.97p5/SCons/Script/SConscript.py", line 520:

    return apply(_SConscript, [self.fs,] + files, subst_kw)

I have attempted to fix these issues directly, but there are so many of them, and I'm not familiar enough with scons to know if it will change (i.e. Break) the build.  I would rather not have to update the usage in thousands of lines of scons usage, simultaneously updating python and scons.  That would be a big project with significant risk.  If I can update one thing and get it to work, then I can go through and update each thing separately, keeping them working along the way.

So if you have a better idea of how to fix this issue, for example by correcting the usage in scons (before updating any versions of the tools) I would be happy to hear them.

Rob,

Are you talking about the return value from a SCons builder?
xyz=env.SharedLibrary()

For example..
In which case you should always (have) expected a list to be returned..

Nodes turn into NodeLists with python 2.6 or 2.7, using the same version of all the tools (scons included).  I haven't been able to boil that down to one construct or line of code, so I was attempting to upgrade scons & my build files first.

Rob,

What's holding you back at python 2.5?

Scons users,

I've inherited an SCons build that is using python 2.5 and scons version 0.97.  I would like to bring the version of scons up as much as possible, without having to update python at the same time (there are bigger issues with that).  So I was looking at release notes to find the last version that worked with 2.5, which seems to suggest 2.3.2 because in the 2.3.3 release notes it states that support for python 2.4 was dropped (for 2.7 IIRC).  However, 2.3.2 has several constructs in it that don't work in python 2.5,  like python3 except statements, string format methods, etc.
Does anyone know what the highest version that is fully functional in python 2.5?

Thanks,

Rob Boehne
