I updated my Homegear setup (via OpenHabian) yesterday evening from 0.7.27-1824 to version 0.7.38-2757.
After that homegear -r does not work any more? I get the following error: homegear: symbol lookup error: homegear: undefined symbol: _ZN3Ipc8VariableC1EPKc
It works now also for my environment. Unfortunately not totally show how this was fixed. I updated/upgraded openhab and reinstalled homegear in random orders with some reboots of the raspberry. Finally it worked. Not very professional but maybe this will also help others.
Heya
Exactly the same problem here on Raspbian stock image.
So just to be sure, did the uninstall and reinstall kill any of your homematic configuration? Or was it just as simple as apt-get remove homegear / install?
EDIT: I did an apt-get install --reinstall homegear
Which fixed the issue. I have the feeling that during the last upgrade I did not get asked alle the questions about keeping the configuration. The reinstall did this and now it works all fine.
