toolchain build python3 kivy fails downloading freetype

[rjriv]

Using macOS 12.4, XCode 13.4.1, and Python 3.10.5 I have tried to install kivy-ios following the instructions here on github.

I created a virtual environment, installed kivy, and ensured that I could create and run a simple application:

from kivy.app import App

class MyApp(App):
    pass

MyApp().run()

Then I installed kivy-ios, and the prerequisite "brew" items. So far so good.

Then when I execute:

toolchain build python3 kivy

the execution fails when trying to download "freetype," which prevents the build from proceeding any further:

[INFO    ] Downloading https://download.savannah.gnu.org/releases/freetype/freetype-old/freetype-2.5.5.tar.bz2
[WARNING ] Download failed. Retrying in 1 second...
[WARNING ] Download failed. Retrying in 1 second...
[WARNING ] Download failed. Retrying in 1 second...
[WARNING ] Download failed. Retrying in 1 second...
[ERROR   ] Max download attempts reached: 5

This file can be downloaded manually, so I am not sure if this is a configuration error or if there is some incompatibility with my system.

I can't reproduce it (on CI and locally), are you still encountering the issue? (Usually is a temporary failure)

I'm not seeing that issue, but instead the download "finishes" immediately but the file is not found when trying to extract:

FileNotFoundError: [Errno 2] No such file or directory: '/Users/dlewanda/Development/Python-iOS/.cache/freetype-freetype-2.5.5.tar.bz2'

Thankfully I was able to manually download the file from the URL @rjriv specified above (not in my output) and place it in the .cache directory with the different name (freetype-freetype-2.5.5.tar.bz2 instead of freetype-2.5.5.tar.bz2) and I was able to get past that error, but it seems like there's something up with where freetype is being fetched from.

I am in the same dev environment and encountered this same problem. After a bit of digging, I found out it was due to a client-side SSL issue.

The command I ran to fix this issue: /Applications/Python\ 3.10/Install\ Certificates.command

The stack overflow post that actually helped me understand the problem: here

[rjriv]

Hi @ashlynns, yes, this is what I get for for not paying attention to the python install dialog on macOS... "Please run the Install Certificates.command to finish the installation."

Sigh.

This is not a kivy-ios issue and can be closed.

Thanks for the help!
