Symbol Lookup Error

[japita-se]

1.Installed latest OZW

2. Installed latest node and openzwave-shared.
3. Start my script, got this error: undefined symbol: _ZN9OpenZWave7Options6CreateERKNSt7__cxx1112b

Same issue here. Here node-red output logs:

Seems like this only happens with Raspbian Stretch, everything works perfectly on Raspbian Jessie.

Programming tip: the undefined symbol:xxx error means that you've compiled openzwave-shared against a different library version than the one that is found when you're using the library. Go directly to : https://demangler.com/ and add the missing symbol into the search box, this yields: OpenZWave::Options::Create(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)

... which means: this C++ method with the signature above is missing from the OpenZWave library that it finds on the system. Most probably you have the library file libopenzwave.so.1.x in multiple versions in multiple locations

[ekarak]

so in order to resolve this, first try to locate which file is loaded by node-red:

1) grab the node.js openzwave library file from the error: node-red: symbol lookup error: /home/pi/.node-red/node_modules/openzwave-shared/build/Release/openzwave_shared.node: undefined symbol: ... In our case, this is /home/pi/.node-red/node_modules/openzwave-shared/build/Release/openzwave_shared.node

2) run ldd -r against that file, ie. ldd -r /home/pi/.node-red/node_modules/openzwave-shared/build/Release/openzwave_shared.node

On my Raspberry (running Raspbian stretch) I get:

    /usr/lib/arm-linux-gnueabihf/libarmmem.so (0xb6ea0000)
    libopenzwave.so.1.5 => /usr/lib/arm-linux-gnueabihf/libopenzwave.so.1.5 (0xb6da4000)
    libstdc++.so.6 => /usr/lib/arm-linux-gnueabihf/libstdc++.so.6 (0xb6c5c000)
...

On the 2nd line there's an entry noting that for libopenzwave.so.1.5 the linker has resolved it (=>) to /usr/lib/arm-linux-gnueabihf/libopenzwave.so.1.5 , so there's the actual OpenZwave library that is loaded (and is of a previous version than the one the plugin is compiled against)

[ekarak]

Then there's this grep trick to get you the correct library:

root@pi-stretch:/# find /usr/ -type f -name 'libopenzwave.so.*' |xargs grep -al  _ZN9OpenZWave7Options6CreateERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEES8_S8_
/usr/lib/arm-linux-gnueabihf/libopenzwave.so.1.5
root@pi-stretch:/# 

[robertsLando]

In my case, on stretch, the only way to fix this has been:

sudo cp /usr/local/lib/libopen* /usr/lib/arm-linux-gnueabihf

I had the same problem on Raspbian Stretch following the instructions of https://github.com/OpenZWave/node-openzwave-shared/blob/master/README-raspbian.md. In my case, it was caused by gcc/g++. Following Option 1 of http://node-arm.herokuapp.com/ solves the problem.
