I am trying to package a python app in iOS. The app is very simple with just 1 line:

from firebase import firebase

I follow the instruction from this link:

https://github.com/kivy/kivy-ios

Everything is good. I use Xcode to push the app to a virtual Simulator. I need to install a recipe pycrypto. So I move to the kivy-ios folder and run the following code as instructed:

sudo ./toolchain.py build pycrypto

It failed with the following error (or warning):

hcaos-iMac:kivy-ios hcao$ sudo ./toolchain.py build pycrypto

I'm using Mojave in VirtualBox, python3. I have no idea why everything is "ignoring". My app can be packaged successfully in Linux for android. I am not a Mac user at all. Please help me resolve the issue. Anything is appreciated.

Look like pycrypto was already compiled from a previous build, and so it didn't do anything.

After compiling a new recipe, you need to update your project to include the new compiled recipe into your project with the command:

./toolchain.py update myproject

Also, please don't use sudo at all, we never ask or need for administrator rights.

  • Thank you so much. You show me how to build and update project with a new recipe. However, I still ran into problem afterward. So I started a new project with just python3. And now I can't build pycrypto. Would you please be kind enough to look at the link````https://stackoverflow.com/questions/57864387/unable-to-build-pycrypto-recipe-in-python3-toolchain```` – user11809703 Sep 10 '19 at 05:19
