error building using Python 3.7.4 on OS X

[freddrake]

Using Python 3.7.4 on OS X with the python3.7 branch of this project, running bin/build, I get the following error:

Downloading ftp://python.infinidat.com/python/sources/zlib-1.2.11.tar.gz
While:
  Installing zlib.
Error: Error downloading extends for URL ftp://python.infinidat.com/python/sources/zlib-1.2.11.tar.gz: <urlopen error ftp error: URLError("ftp error: error_perm('550 No such file or directory.')")>

It looks like zlib-1.2.8.tar.gz is available. Is this a matter of the resources needed for the branch just not being available because the branch isn't finished?

Hi. The 3.7 branch is still work in progress. We hope to finish it soon. Please use the "develop" branch for now.

[freddrake]

Can the develop branch be used to build Python 3.7? What version of Python is required to run the develop branch?

[wiggin15]

The develop branch currently builds Python v3.5.1. We are working to finalize the 3.7 branch and merge it.

If you want to use your own sources instead of the Infinidat FTP, you can make the following changes:

diff --git a/buildout-build.cfg b/buildout-build.cfg
index 7949b88..509dda5 100644
--- a/buildout-build.cfg
+++ b/buildout-build.cfg

Change the sources list accordingly:

And download the sources before building:

grep -o 'http.*' sources | xargs wget --directory-prefix .download_cache --no-clobber --no-verbose

I have a fork of this project at work where FTP is blocked by our firewall, and this is the workaround I use. The sources list I provide above tries to use primary sources, but where I couldn't find any uses a university mirror site. Word of warning: some of the links aren't HTTPS and I haven't verified checksums or anything.
All links are correct and working at the time of writing.

Furthermore if you're building using Python 3, you need to patch infi.recipe.python as it only currently supports Python 2.

infi.recipe.python-0.6.23-pack.patch:

This patch makes it work on Python 3
