A package can have the following states:

  • Installed - the package is installed. An installed package is compiled into the IDE and its classes are available in the component palette.
  • AutoCreated - the package is part of the IDE, it can not be uninstalled.
  • Install on next start - the package is not yet installed, but will be compiled into the IDE and will be installed after exiting the IDE and starting the new IDE. You compile a new IDE in Tools -> Build Lazarus.
  • Uninstall on next start (unless needed by an installed package) - This package was installed automatically because it was needed by a package that was installed normally. When the normally installed package is uninstalled this package will be uninstalled as well.
