Dependencies / System Requirements

Tested on Linux. Changes to be made:

An updated version will be posted as soon as possible.


  • Place sources in a subdirectory of <$LazarusDir>/components.
  • In Components -> Open Package File, open rxnew.lpk.
  • Compile the component to verify that everything is ok.
  • Install and let Lazarus rebuild.
