Still working?

[edikay]

Your library is still working? Because when Im trying ./get_code then I get errors:

Can you help me? I know last update 2 years ago.

It seems you are missing the library file for librpi_ws281x.so
this repo just contains the binding code for java.

get_code.sh is/was just a terrible hackish way to get the code from here: https://github.com/jgarff/rpi_ws281x and compile it.
did you run in from the subdir? It might behave terrible in terms of working directory.

sorry, wrong lead above, the ereror is related to something that changed in the rpilib - my lousy script does not pin it to a commit or tag as it should.
best head over to the lib repo and get it to compile, then you can update get_code.sh accordingly (or better make it better - its painful reading the own code from years ago 🤣 )
