Kivy not working on Ubuntu 17.10

[Alejandro Mendez]

Hi,

I have installed kivy in Ubuntu 17.10 and I can't seem to make it work. I have tried many things.

I have tried with Python 2 and 3, and also in a virtual machine.

With this simple app:

from kivy.app import App

App().run()

I get:

[INFO   ] [Logger      ] Record log in /home/twistx77/.kivy/logs/kivy_17-10-21_1.txt

[INFO   ] [Kivy        ] v1.10.0

[INFO   ] [Python      ] v3.6.3 (default, Oct  3 2017, 21:45:48) 

[GCC 7.2.0]

     import kivy._event

 ImportError: /usr/lib/python3/dist-packages/kivy/_event.cpython-36m-x86_64-linux-gnu.so: undefined symbol: PyFPE_jbuf

Is this a bug or am I doing something wrong?

Thank you.

I've got the same problem with the same error message...

I have posted and Issue on their github https://github.com/kivy/kivy/issues/5453

I have the same issue, when I try to run a simple kivy example (3D rendering). Kivy is not working

Ubuntu version: 17.10

Hi.

So, trying to look into this, but so many things are broken in 17.10 it hard to know where to start. I will post back on this thread after investigating, but please understand this more an ubuntu/python compatibility issue that a kivy issue.

Peace out

Hi,

Thank you for trying anyway. If I had enough knowledge to fix it, I would. I have created an issue in theri github.  https://github.com/kivy/kivy/issues/5453

If it is a ubuntu/python compatibility issue could this be forward to the python developers?

Thank you.

Okay, relief. Yes, the binary installer for Kivy seems broken on 17.10. Luckily, you can get it working if you build from source. So, follow the instruction here for 16.04:

    https://kivy.org/docs/installation/installation.html#installation-devel

But leave out

    python-gst0.10
    gstreamer0.10-plugins-good

from the dependencies. That seems to get Kivy up and running. I have not done extensive testing, so if you encounter issues, please feel free to report them here.

[Alejandro Méndez A.]

Thanks!

I will try that out.

I imagine I need to unistall kivy completely before compiling from source, right?

I have tried and it works.

I will have to try with python 3.

Thank you very much.
