Python plugins not working Topic is solved

[thomasvillagers]

Hi,

on my raspy, python plugins do not work anymore with the latest beta

Version: 3.6707
Build Hash: 6674ca2

They did work before the update. Now, the start log tells me:

: 2017-02-14 16:20:33.647 PluginSystem: Failed dynamic library load, install the latest libpython3.x library that is available for your platform.

But libpython3.4 is installed on the system, plugins worked before V 3.6707.

Do I miss something here?

I'm experiencing exactly the same problem. I opened a bug report for it as well: https://github.com/domoticz/domoticz/issues/1230

Two minutes ago I compiled V3.6708 with python support with your buienradar plugin. Everything works fine!

I'm sorry, still no luck:

Works for me to!

[ffes]

v3.6708 still has the problem for me:

Are we missing some additional required packages?

I haven't changed this for a while (wasn't broken so I didn't try and fix it) but will have a look at it.

[ffes]

Just did

Code: Select all

sudo apt-get install python3-dev

Which seems to solve it. A bit strange that it is suddenly needed.

As far as I know this was always needed, at least if you compile from source

[ffes]

I never compiled from sources (at least on my pi). Previous betas didn't need this. But apparently python3-dev is needed to run.

[thomasvillagers]

that fixed it, thank you!

[Holland]

Reinstalling python3-dev did the trick

Strange, before 3.6707 (or maybe 1 version earlier) Python and the plugins were running smoothly. And yes, had python3-dev already installed.
Could also be related that I did a; apt-get install update+upgrade.

I tried an upgrade+update on Ubuntu 16.04 and it still worked afterwards without a re-install.

[G3rard]

On Ubuntu 14.04 and Domoticz v3.6708 the plugins are also still working without a re-install.

[mikeoo]

Upgraded to the latest beta 3.7349 result with the error

PluginSystem: Failed dynamic library load, install the latest libpython3.x library that is available for your platform

Tried
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install python3-dev

But stil same error.

[Dnpwwo]

@mikeoo,

You need to provide more details.

• Was it ever working?
• What OS are you running?
• Have you installed libpython3.x as the error suggests? (python3-dev is for when you build from source)

[mikeoo]

@Dnpwwo

I just noticed the error and not sure if is was there before.
Using on Raspbian GNU/Linux 7 (wheezy)
Tried to run: sudo apt-get install libpython3.4 result with: Couldn't find any package by regex 'libpython3.4'

Bit lost now

[Dnpwwo]

@mikeoo,

Wheezy does not have a version of Python compatible with Domoticz. If you don't want to upgrade to Jessie then there are instructions here: http://www.domoticz.com/wiki/Linux#Prob ... ing_Python

In short you need to build a version from source using:

Code: Select all

 wget https://www.python.org/ftp/python/3.5.2/Python-3.5.2.tar.xz
 tar -xvf Python-3.5.2.tar.xz
 cd Python-3.5.2
 ./configure --enable-shared
 make
 sudo make install

That one fixed the problem

Status: PluginSystem: Started, Python version '3.5.2'.

Thanks for the support.

Hey,

Just wanted to ask, is it usual for it to take a considerable long time after the last command here? I'm not sure if I've had a crash or not.

It's taking ages after the MAKE command, outputting blocks of text after every few minutes like this:

gcc -pthread -c -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -std=c99 -Wextra -Wno-unused-result -Wno-unused-parameter -Wno-missing-field-initializers -I. -I./Include -fPIC -DPy_BUILD_CORE -o Objects/unicodeobject.o Objects/unicodeobject.c
