Hi,
wiringPi is a dependency of the driver. For installation instructions visit: http://wiringpi.com/download-and-install/
Yes, I have installed wiringPi, gpio -v works and I can even use the WiringPi-Node lib with node without getting any runtime error. I installed this node hx711 lib using: npm install hx711 --save, is there something missing in the package?
Hi, how did you install wiringPi? Check if you have a libWiringPi in your LD_LIBRARY_PATH or modify the binding.gyp file to reference the .so object using an absolute path and recompile the library.
Hope this helps.
I solved it using the binding.gyp adding "libraries": [ "/usr/local/lib/libwiringPi.so" ] comment out -ldflags and then ran node-gyp build..
Maybe it also worked if I just set the LD_LIBRARY_PATH and then ran node.gyb build... i don't know.
thanks.
Thanks for letting me know.
Would be great if you could make a pull request as it seems that this is the more compatible way of doing things. Otherwise it would be great if you could just post your updated gyp file so I can edit it in.
Thanks Daniel
Hi,
Found your nodejs lib for hx711, but I keep getting error: missing symbol. (I am new at nodejs) node: symbol lookup error: /home/ubuntu/test-nodejs/node_modules/hx711/build/Release/hx711.node: undefined symbol: wiringPiSetup
Get this when running code below:
var hx711 = require('hx711'); const SCLK = 5; const DATA = 6; var sensor = hx711(SCLK, DATA); << error.
Found the wiringPi/wiringPi/wiringPi.h in the src of wiringPi from git, and it seem to contain wiringPiSetup etc, but I don't know where to put it..or how to fix this.
Please advice.
Cheers
