Error: "Makefile:281: *** missing separator. Stop." when compiling python3/openssl/kivy

[Jean-Sebastien Provost]

Hello experts,

I'm a newbie with kivy and I just finished my first app and wanted to created for IOS. I've followed the instruction and was able to do these steps successfully:

>python3 -m venv venv
>. venv/bin/activate
>pip3 install kivy-ios
>xcode-select --install
>brew install autoconf automake libtool pkg-config
>brew link libtool  #Although it says that it already exists on my machine
>sudo pip3 install Cython==0.29.17


Then I did:
>toolchain build python3 openssl kivy

And this is where I'm having issues, everything seems to be working fine for 15 minutes and then it crashes;
I copied part of the log below. I am using a Mac with OSX 10.13.6 with Xcode 10.2 (although might not be useful at this point).

I have no clue why it's happening and since I'm not necessarily too familiar, I don't know if you would need more information.
Please don't hesitate to ask if needed.
 
Thank you very much,

Don't do "sudo pip install". Just "pip install" for cython... Does that help?

[Jean-Sebastien Provost]

Thanks Zencode for your reply, I really appreciate.

I did what you suggested and I got a different error this time. It's related to libffi library. Here is the error message.

[Jean-Sebastien Provost]

Actually I did it again from scratch using pip instead of sudo pip for Cython and I got the same initial error.

[ZenCODE]

If possible, try checking out the latest master branch and retrying? If the problem still occurs, please can you create a new issue here with all the logs included?  https://github.com/kivy/kivy-ios/issues

Thanks

[Jean-Sebastien Provost]

I had a bunch of hidden files interfering with the installation. Once everything cleared, it worked.
