Hi all,

Thanks to Emanuele Gaifas [1], the manylinux docker images now include
Python 3.7 (currently the rc1 release), so if you want you can now
start building and uploading wheels for 3.7 ahead of its expected
release on June 27 [2].

I just tried out the latest manylinux1 image along with updated scripts from matthew-brett/multibuild and find my wheels seem to 
have shrunk eg

reportlab-3.4.42-cp27-cp27m-manylinux1_x86_64.whl

old: 3796941
new: 2516821

looking in side the wheels it looks like the .so files have been slimmed. Does anyone know if that is just because they no longer 
include debugging information etc etc?

If you haven't built in a while, this could well be the result of
merging https://github.com/matthew-brett/multibuild/pull/140 - which
introduced stripped Linux binaries.

Cheers,

As that's seemingly a mystery solved, hijacking the thread to ask has
anyone seen what'd LTO do to wheel sizes?

Debian has AFAIK enabled LTO for Python and some packages grab their build
settings from how the Python has been built. Organisations roll their own
non-manylinux wheels for various reasons, so there could be actual interest
in any gains.

There's pre-existing speculation from the GCC list in regards to
performance from a while back, but that discussion went nowhere:

thanks very much. Looking in configure_build.sh it seems I can get a debugging build by exporting STRIP_FLAGS='' or is there a 
another way?

Right - simplest would be to put STRIP_FLAGS=" " (notice space inside
quotes) in your `env_vars.sh` file, to disable the stripping.  This
gets sourced before `configure_build.sh`.

Cheers,

Matthew

Message-ID: <cc3581a2-ea4b-ab6d-0196-1724956f4b3e@chamonix.reportlab.co.uk>

Anyone here knowledgeable about appveyor? Python 3.7 is now official and I currently cannot get appveyor to build 3.7 amd-x64 or 
32bit. The envirnments list for python shows 3.6, but no 3.7. It could be my attempted usage of 3.7 is wrong though. So has anyone 
else tried to test 3.7 building?
