symbol lookup error

[rampIc15]

I configured a GPIO ( GPIO 25 to be exact and pulled up)
I watch the pin for state change, the following error occurs when the switch is pressed.

node: symbol lookup error: /home/pi/mytools/gateway/node_modules/onoff/node_modules/epoll/build/Release/epoll.node: undefined symbol: _ZN4node12MakeCallbackEN2v86HandleINS0_6ObjectEEENS1_INS0_8FunctionEEEiPNS1_INS0_5ValueEEE

I tried upgrading wheezy but still did not resolve the issue. Current version I am at :

Linux version 4.1.7+ (dc4@dc4-XPS13-9333) (gcc version 4.8.3 20140303 (prerelease) (crosstool-NG linaro-1.13.1+bzr2650 - Linaro GCC 2014.03) ) #817 PREEMPT Sat Sep 19 15:25:36 BST 2015

onoff version is 1.0.3.

Was onoff installed with one version of Node.js and used with a different version Node.js? If so, this isn't a good idea. In this case please reinstall onoff with npm install onoff.

If the issue persists, please post the complete output of the following commands:

node -v
npm -v
cd
mkdir testonoff
cd testonoff
npm install onoff

Thanks!! for a quick response.

I tried re-installing onoff but the issue is not resolved.

Node.js v0.10.0 and npm v1.2.14 are very very old! Where does this version of Node.js come from? I'm actually surprised that onoff appears to have installed successfully. Internally onoff depends on epoll which in turn depends on nan v2.1.x. nan v2.1.x supports Node.js 0.10.29+.

What's the output of the following commands?

cd /home/pi/mytools/test/node_modules/onoff/node_modules/epoll/test
./run-tests

Is there anything preventing you from using Node.js v4 or higher?

[rampIc15]

yep. node is old. This Pi has been running fine for a while so did not bother to update it.

Anyhow I installed new version of node and npm. Re-installed onoff. Everything good now!.
Thanks for your help. And great job with onoff.

cheers !

Thanks!
Have fun with onoff.
