ImportError: No module named AlljoynRouter

[mclarkk]

Hi there! I'm trying to install these Python AllJoyn bindings on a Raspberry Pi. I have AllJoyn installed and the alljoyn-daemon running successfully on it. I installed this module with the following command (I added the option build_ext -n -I/home/pi/alljoyn-16.04a-src/alljoyn_core/inc because the original build couldn't find my AllJoyn Init.h when trying to build the router):

$> sudo python setup.py install build_ext -n -I/home/pi/alljoyn-16.04a-src/alljoyn_core/inc
running install

Removing /usr/local/lib/python2.7/dist-packages/AllJoynPy-1.0.egg-info
Writing /usr/local/lib/python2.7/dist-packages/AllJoynPy-1.0.egg-info

So it looks like installation was successful, including the build of the AlljoynRouter. However, when I go to run BasicService.py (with alljoyn-daemon running) I get the following:

Traceback (most recent call last):
  File "BasicService.py", line 3, in <module>
    from AllJoynPy import AllJoyn, AboutListener, MsgArg, AboutData, \
  File "/usr/local/lib/python2.7/dist-packages/AllJoynPy/__init__.py", line 22, in <module>
    import AlljoynRouter
ImportError: No module named AlljoynRouter

I don't see AlljoynRouter.so under build/lib.linux-armv7l-2.7, nor do I see Router.o under build/temp.linux-armv7l-2.7/AllJoyn, so perhaps the extension is not getting installed? Do you have any idea about what might be causing that?

Thank you!

You may want to try https://github.com/glennpierce/core-alljoyn I remember trying to get it to build with the rest of the AllJoyn source code. I attempted to build the AlljoynRouter.so with scons. The command scons OS=linux WS=off OE_BASE=/usr BR=on BINDINGS=c,cpp,python works for me. You also need your cross compile stuff obviously. I could never work out how to place the generated alljoyn_python/AllJoynPy/AllJoynPythonRouter.so in the correct lib directory. No one on the mailing list ever replied to me about that. I may have ended up copying it to the Python path. The AllJoyn build system seems like it could be made easier. I got a little disillusioned having to have AllJoynPythonRouter.so. It only exists to have the built in router ie two functions because for some reason those functions weren't in the dynamic alljoyn library. I basically had to compile a huge static lib just for those. You may want to edit alljoyn_python/AllJoynPy/__init__.py and remove import AllJoynPythonRouter and change def RouterInit(self): AllJoynPythonRouter.RouterInit() def RouterShutdown(self): AllJoynPythonRouter.RouterShutdown() to def RouterInit(self): pass def RouterShutdown(self): pass If you are using the alljoyn -router binary you shouldn't need those functions. I probably should have just givin up having support for a built in router. It was too much hassle. Unfortunately I don't work on these bindings anymore as my Allplay speakers (Alljoyn based) all decided to fail so I ended up creating my own music sync system with cheap components and gstreamer. Good luck

Thanks for the reply! Yeah, the whole distributed D-Bus idea behind AllJoyn seems like a good idea, but the codebase is a mess with regards to usability. I'll give it another shot this weekend, but I'm thinking it might actually be less hassle to whip up my own lightweight bus that captures the good ideas of AllJoyn without all the enterprise-y baggage (none of the devices I have support AllJoyn and would need to have adapters written anyway). Thanks again!

Yes I do wondered if all the extra complication of these IPC mechanisms are worth it. Unless the is some particular need it is often easier using restful xml or json interfaces. Good luck
