[mythtv-users] New Mini Core Duo, No Video

[Todd Ignasiak]

After incorporating your step 5, I got a lot farther.  I got it to finish
the compile (after on other update in the QT code, Actions.cpp was looking
for malloc.h instead of sys/malloc.h).

Now, I'm caught up to you:

./mythfrontend
dyld: Symbol not found: __ZTV24CaptionServiceDescriptor
  Referenced from:
/Users/tji/Build/MythTV/MythFrontend.app/Contents/MacOS/./../Frameworks/mythtv.framework/mythtv
  Expected in: flat namespace

Trace/BPT trap


Apparently that is part of the ATSC closed caption stuff..
