Pybluez and Gattlib error

Question

I'm trying to run a script that is using pybluez library for Ble, but when I'm running the script I got this error:

    from gattlib import *
    ImportError:  No module named gattlib

So I tried to install the gattlib as super user with the command:

sudo pip install gattlib 

on my Raspberry but I got this error:

/usr/bin/ld: cannot find -lboost_thread
collect2: error: ld returned 1 exit status
error:command 'c++' failed with exit status 1

(O.S Raspbian running on Raspberry Pi 3)

Script:

    # bluetooth low energy scan
      from bluetooth.ble import DiscoveryService

      service = DiscoveryService()
      devices = service.discover(2)

      for address, name in devices.items():
          print("name: {}, address: {}".format(name, address))

How can I solve my problem?

Answer 1

Thats because one of the dependencies is missing. Its also better that u download it and compile it from source. install mercurial

sudo apt-get install mercurial

the clone the source of gattlib

hg clone https://bitbucket.org/OscarAcena/pygattlib
cd pygattlib
cat DEPENDS

you need to install all those dependencies, the reason you getting that error is because you didn't install libboost-thread-dev.

sudo apt-get install libboost-thread-dev

now install gattlib like any other python module.

sudo python setup.py install

That should fix it. Thats how I install it on the RPi 3

Answer 2

I have the same issue with Python 3 on a Raspberry Pi 3, and I had to do some extra steps, so I'll expand over @michael-jalloh answer:

1. Install Mercurial

   sudo apt-get install mercurial

2. Then, clone gattlib's source:

   hg clone https://bitbucket.org/OscarAcena/pygattlib cd pygattlib cat DEPENDS

3. Then install glib-2.0:

   sudo apt-get install libglib2.0-dev

4. Then install boost:

   sudo apt-get install libboost-all-dev

5. At this point will still fail because it's looking for libboost_python-py34, and a newer version is installed libboost_python-py35, so you need to run:

   sudo ln -s /dir/to/libboost/libboost_python-py35.so /dir/to/libboost/libboost_python-py34.so

   In my device the /dir/to/libboost is /usr/lib/arm-linux-gnueabihf

6. Now you can install gattlib

   sudo python setup.py install

Hope this helps!!!

Answer 3

This post worked for me. The key is to change the dependency to 36 version of the library.
