Fixing dyld: Symbol not found Expected in: flat namespace error

When trying to load Python on iOS within a framework I was getting the following error:

dyld: Symbol not found: _GENERAL_NAME_free
  Referenced from: /.../data/Containers/Bundle/Application/D4..9D/

  Expected in: flat namespace

Expected in flat namespace? What? 

What's also interesting is that it would load fine if all the libraries were linked directly to the executable.  Well turns out it was giving the error when just liking to the Python.framework because that was only linking Python, not all the dependencies python has (libffi and openssl). 

I had the correct CFLAGS and LDFLAGS for including a dependency and headers so it compiled fine. But when it went to load, iOS didn't know where to find the dependent libraries!  Added in the missing " -l<lib>" flags, recompiled, verified with "otool -L" and all is good to go!

Happy coding!

Kivy vs React-Native for building cross platform mobile apps

I've built three apps now using Kivy and one with React-Native, just wanted to share my thoughts on both.

Just a warning, I am strongly biased towards python and this is all based on opinion and experience and is thus worth what you pay for it. I don't claim to be an expert in either of these, just have worked with each for several months.  If something is incorrect I'd love to hear advice.

Nice to be able to run natively on the desktop WITHOUT a simulatorPython is easy to work withUse (almost) any python libraryVery easy to create custom widgetsKivy properties and data binding just work. Way nicer than React's "state" / flux / redux whatever you want to call it (stupid?). Native interfaces (pyjnius) and (pyobjc)Runs and feels pretty smooth Cons:Default widget toolkit looks like Android 4.4. Requiring you use your own widgets or a theming kit like KivyMD if styling bothers youCreating dynamic widgets declaratively is not yet s…

Control Systems in Python - Part 1 - Bode and Step Response

I hate matlab with passion, yet sadly, nearly everyone uses it.  I'm a fan of Python and open source stuff so here's a simple article on how to do some common control systems stuff in Python.

First we need to make sure the environment is setup.
Install IPython (or you can use any other python shell, but a unicode supported shell is preferred)Install python-control (numpy, scipy)Install sympy
These should do if your on Ubuntu/debian:

sudo apt-get install python-sympy python-numpy python-scipy python-matplotlib ipython
Then you need to install python control, see How to download and install python-control
Intro to using SympyOpen ipython and run the following:

import sympy from sympy import * sympy.init_printing() s = Symbol('s')

Now we can do things like define transfer functions using the symbolic variable s.

We can expand the bottom using the .simplify() method

and we can do something more complex like...
which is really nice because it does all the multiplication for us... and it’…
