The quick answer about -v -v can be gotten with "./nox_core --help": -v, --verbose make console log verbose (shows INFO messages -- use twice for DBG)
The longer answer is that -v -v puts it into "very verbose" mode. NOX's logging can actually be configured with quite a lot of flexibility through several mechanisms, including at runtime... but the GUI doesn't currently know anything about that. In general, you probably DO want all levels of log messages to be sent to the GUI so that you can then use the GUI's filtering mechanism (which lets you filter them after the fact). This really should be the default for the GUI, and I have a local branch which does this, so it's quite possible we'll see it in a future version of NOX. About the Components section being empty... if I recall correctly (and it's entirely possible that I don't), the Components section is populated by watching the DBG messages about component loading when NOX starts up. With only one -v, they never get to the GUI. -- Murphy On Sep 12, 2011, at 7:34 PM, Lucas Henrique Mauricio wrote: > I figured it out how to solve the missing library.
