Possible reasons: - The register procedure was not called, because you didn't check the 'Has Register procedure' for this unit in the package editor. - You didn't start the new IDE, but the old. Start the IDE in the terminal. You will see where the new lazarus executable is created. Hint: When you select the unit in the package editor you can see the registered components of this unit. > The long story for question 2: > > I made a package for the component, converted the dfm to lfm, fixed some > code and commented things for later until it compiles okay.

You can use the command line tool lazbuild to compile an IDE with your packages: http://wiki.lazarus.freepascal.org/lazbuild > All that occured with: > > Lazarus svn 25285 and 25631 > fpc 2.4.0 > FreeBSD 7.2 Mattias -- _______________________________________________ Lazarus mailing list [email protected] http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
