Compile error with signalmonitor

[otto at kolsi dot fi]

Following compile error happens in Fedora 13, svnversion 25549:

signalmonitor.cpp: In static member function ‘static SignalMonitor* SignalMonitor::Init(QString, int, ChannelBase*)’:
signalmonitor.cpp:136: error: cannot dynamic_cast ‘channel’ (of type ‘class ChannelBase*’) to type ‘struct V4LChannel*’ (target is not pointer or reference to complete type)
make[2]: *** [signalmonitor.o] Error 1

Is that the first error?

This:

target is not pointer or reference to complete type

Makes me think the V4LChannel header is not happy.

(In [25553]) Use ChannelBase?, not V4LChannel as the "catch all" type. Fixes #8720
