Hi folks. So my screensaver broke on 10.6, along with everybody
else's, and I'm told that's because it has to be compiled for the 64-
bit architecture, because System Prefs is a 64-bit app on 10.6. So I
set up a conditional compilation thing where it compiles three versions:
- ppc against the 10.4 SDK (deployment target 10.4), GCC 4.0
- intel against the 10.4 SDK (deployment target 10.4), GCC 4.0
- intel 64-bit against the 10.6 SDK (deployment target 10.6), GCC 4.2
These settings are from a web page about how to get a screensaver
to work on 10.6; I don't know why the GCC version needs to vary, for
example. I'm just following orders. :->
This all seems to work fine, after much fussing about with
deprecated APIs and such. My screensaver now builds and links without
errors, and lipo gives me promising-looking output showing my three
architectures. The screensaver runs fine on 10.5 intel; haven't tried
it on 10.4 or ppc, but I imagine it's fine there too.
But on 10.6 I still get the same error from System Preferences.
Opened Console and saw this:
10/11/09 2:51:18 PM ScreenSaverEngine[204] Error loading ...:
dlopen(..., 265): no suitable image found. Did find:
...: GC capability mismatch
10/11/09 2:51:18 PM ScreenSaverEngine[204] ScreenSaverModules: can't
get principalClass for ...
So I guess System Preferences doesn't like my garbage collection
setting (which is set to "Unsupported"). Do I really need to turn GC
on to get my screensaver to work?? I haven't seen anything about that
elsewhere, so this catches me a bit off guard. I would have assumed
that they would build it to be able to handle either style.
Is there any way around this? Since I want my screensaver to still
run on 10.4, this is more than a little inconvenient.
Thanks for any advice!
