Marc,
The component manager requires certain resources (in the old-fashioned
Resource manager sense) to be defined properly. Check to make sure
there is a 'thng' resource with the proper component type, subtype,
and manufacturer. Also, make sure there is a 'dlle' string resource
which has the CORRECT name for your component entry point.
Also, make sure that the component entry point is exported
in the dylib code for your component in *.component/Contents/MacOS/
In the terminal window you can us the "nm" command on the dylib
to get a list of symbols. Exported names have an uppercase "T"
by them. The entry point names usually end in "Entry".
If it's not exported, then you have to put the name in your .exp file
in Project Builder. There are other things that can wrong, but these
are the common problems...
Good Luck!

Best thing for you to do is check these resources with the ones in
AudioUnits you know to be working correctly
I was just wondering what conditions need to exist in order for the
Component Manager to accept a component as a valid Audio Unit. I haven't
had problems with my previous AUs, but the current one I'm working on
won't show up (I'm testing with all of the SDK test host apps, Find Units,
and Logic).
Do certain things need to exist in *.component/Contents/Resources/*.rsrc
resource file? Or does the Info.plist file play a role? Or do certain
methods called in the executable need to succeed? I'm just wondering if
there are specific places I can look at for mistakes I made. That would
be much preferable to aimlessly and unsuccessfuly mucking around, as I
have been doing...
Thanks,
Marc
