Description Hin-Tak Leung 2016-05-17 22:04:12 UTC
Following up on

The current bundled ironpython is a snapshot off master from nearly 5 years ago,
577 commits behind current master and 614 behind 
ipy-2.7-maint (and 130 from the last common ancestor with ipy-2.7-maint)
 as of now. It is also a bit surprising it claims to be 3.0 but did not 
come from git://github.com/IronLanguages/ironpython3.git .

It appears that most current activity seems to be on 
git://github.com/IronLanguages/main.git:ipy-2.7-maint - would it make 
sense to switch to a more recent git://github.com/IronLanguages/main.git:ipy-2.7-maint
 or one of its release tags instead?

I would suggest upgrading to 2.7.5 release, or the next (2.7.6) if it is coming out any time soon.

Also, note that more recent version of ironpython comes with tuned version of the python standard library modules. So it might be a shock during recursive copying of the install.
Comment 2 Alexis Christoforides 2016-05-19 14:51:41 UTC

I briefly attempted to build a more recent version of IronPython but the Mono build was broken in several places. I'll come around to it again, but if anyone knows of a recent version that builds I'll switch to it right away.
Comment 3 Hin-Tak Leung 2016-05-19 19:40:17 UTC
I don't remember having problem building git://github.com/IronLanguages/main.git ipy-2.7-maint branch a couple of weeks ago with . The ipy-2.7-maint branch is also the HEAD of git://github.com/IronLanguages/main.git  (rather than master), and although it only says 2.7.6-a0... , seem to be where all the recent activities are.
Comment 4 Hin-Tak Leung 2016-05-23 06:56:39 UTC
@Alexis Christoforides : you are right! HEAD does not build with the default target. I did not notice because I was primarily interested in supporting older runtime, and therefore built it with:

xbuild Solutions/IronPython.sln /p:Configuration="v2Release"

This works for both the ipy-2.7.5: tag and current head (2b528dccee9e973b94ac00a0dbc14b0ebb030c6d:). with - I have a bare clone -:

git archive --prefix=2b528dccee9e973b94ac00a0dbc14b0ebb030c6d/ 2b528dccee9e973b94ac00a0dbc14b0ebb030c6d: | ( cd /tmp && tar -xpvf - )

Filed issue upstream - https://github.com/IronLanguages/main/issues/1297 .

xbuild Solutions/IronPython.sln /p:Configuration="Release"

probably only needs a small fix to get it to work; but /p:Configuration="v2Release" works now.

We should probably remove ironpython from our packages since its available as a nuget:
