Hello,

When i try to update domoticz on my Ubuntu server is get this error message:

-- Using builtin Mosquitto library
-- Could NOT find PythonLibs (missing: PYTHON_LIBRARIES PYTHON_INCLUDE_DIRS) (Required is at least version "3.2")
CMake Error at CMakeLists.txt:72 (MESSAGE):
Python3 not found on your system, use USE_PYTHON_PLUGINS=NO or sudo apt-get
install python3-dev)


-- Configuring incomplete, errors occurred!
See also "/home/domoticz/domoticz/CMakeFiles/CMakeOutput.log".

I really need to update to the latest Beta version on my Ubuntu server.

I had the same issue on my ubuntu server.
If you don't need python3 support:

cmake -DCMAKE_BUILD_TYPE=Release -D USE_PYTHON_PLUGINS=NO CMakeLists.txt

make

Hi gennapium,

The error actually says to

Code: Select all

sudo apt-get install python3-dev

not to install python3 itself.

Give that a go.

That does not work!!!

[Dnpwwo]

If installation of python3-dev does not work it is most likely because the cmake version is really old.

It will need to be at least at version 3 to pick up python properly, if you can't upgrade cmake to version 3 (latest I've seen is over 3.6) then you should indeed use:

Code: Select all

cmake -DCMAKE_BUILD_TYPE=Release -D USE_PYTHON_PLUGINS=NO CMakeLists.txt

[gennapium]

Hallo,

I did install:

sudo apt-get install python3-dev

But the problem still exists.

[gennapium]

Ok,


I will give this:
cmake -DCMAKE_BUILD_TYPE=Release -D USE_PYTHON_PLUGINS=NO CMakeLists.txt

a try this evening. See what happens.

Are you running Ubuntu 12.04? If so that has an ancient cmake. You can tell by running:

Code: Select all

cmake --version

There is a backport avaiable, have a look here https://launchpad.net/~george-edison55/ ... -backports or you can build it from source here http://askubuntu.com/questions/679299/i ... tu-precise and get a newer version

Are you running Ubuntu 12.04? If so that has an ancient cmake.

14.04 LTS also has an old version by default.

[gennapium]

I am running Ubuntu 14.04.

Same problem

sudo apt-get install build-essential
wget http://www.cmake.org/files/v3.2/cmake-3.2.2.tar.gz
tar xf cmake-3.2.2.tar.gz
cd cmake-3.2.2
./configure
make
sudo make install

[gennapium]

sudo apt-get install build-essential
wget http://www.cmake.org/files/v3.2/cmake-3.2.2.tar.gz
tar xf cmake-3.2.2.tar.gz
cd cmake-3.2.2
./configure
make
sudo make install

This is the solution ?

[SweetPants]

This is the solution ?

yes

[gennapium]

Great, i will try it this evening.

[gennapium]

sudo apt-get install build-essential
wget http://www.cmake.org/files/v3.2/cmake-3.2.2.tar.gz
tar xf cmake-3.2.2.tar.gz
cd cmake-3.2.2
./configure
make
sudo make install


This did not solve the problem, this however did:

cmake -DCMAKE_BUILD_TYPE=Release -D USE_PYTHON_PLUGINS=NO CMakeLists.txt

[SweetPants]

This did not solve the problem, this however did:
cmake -DCMAKE_BUILD_TYPE=Release -D USE_PYTHON_PLUGINS=NO CMakeLists.txt

It did for me. If you need python3 support later you will run into the same problem again. Better upgrade cmake to version 3.2.x
Did you get any errors after the install of the new cmake?

Hi.
Trying to cross compile with pluginmanager for all synology NAS.
Compile with cmake -DCMAKE_BUILD_TYPE=Release -D USE_PYTHON_PLUGINS=NO CMakeLists.txt working ok.
The latest Python3 for Synology is Python3.5.1.spk, but if I try to cross compile with Python 3.5.1 it's failed.
If I cross compile with Python3.4.1 all is ok, but domoticz give this error: 2016-12-13 22:07:35.344 Error: PluginSystem: Failed load 'libpython3.5.so', Python probably not installed on system.

Is it possible to change this plugin to accept Python 3.4 and 3.5?
BTW using Cmake 3.2.2

Hi Jumbotroll,

Functionally it will work with Python 3.2 and above (test 3.2, 3.4, 3.51 & 3.5.2), I'm in the process of trying to work out a reliable of locating the libarary on differnt flavours of Unix and different versions of Python and how to have a version out very soon.
