Don't upgrade. Carefully erase (everything!), and then reinstall. > Uninstalling old versions, always leaves something behind.

They seem to be versioned, so that should be possible. > It seems to me that I cannot uninstall completely. Simply kill ~/.lazarus on *nix and -alikes, and lazarus dirs in your profile on windows.

There are possibilities, and 0.9.30 should be again a bit more capable than earlier. The most important bits are -pcp= (that sets the configuration directory) and --lazarus-dir that sets the main lazarus dir. Then the some paths should be initialized relative to these paths, and then some script should devise where it is started and pass this info to lazarus using -pcp and --lazarus-dir > If I compile it from scratch, set a few environment options and > register some extension, should it work? Environment options? There are no environment options. By default Lazarus searches its config in the user profile. If it is not there, it initialize an empty, but non functional one. > The same is true for FPC, can it be portable? Standalone FPC works slightly differently. It searches for (roughly) /etc/fpc.cfg or ~/.fpc.cfg and that file should contain mainly the path to the RTL and other precompiled units. Lazarus overrides that by generating and passing an own fpc.cfg. Not unlike Delphi with dcc32.cfg btw. The info for that comes from Lazarus' own configuration. -- _______________________________________________ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
