Stream_Selector (grextras) on Windows

Hi list,

I installed gnuradio (with grextras), uhd libraries on Windows from
sources. My project used stream_selector (C++) class to to dynamically
reconfigure the flow graph at runtime. When I call gr_top_block.stop()/
wait(), the wait() function don’t return in a long time and I must to
my application process to finish.

Could you help me, please?

Best regards,

stop() causes a thread interruption signal
wait() blocks on joining all scheduler threads

If wait is blocking forever then a work function is blocked on something
and not exiting, or for some reason a scheduler thread is not exiting.

I’m really not sure why, but I would like to fix the issue. Can you
narrow down the issue to a subset of the blocks that cause a problem?
code snippet? Is there a reason you think its the stream selector blocks
(for example)?

If I remove the selector object and connect demod_ssb/demod_am to self(),
it OK.

I’m not sure. All of the blocking calls in this block should be
interruptible by boost thread interrupt (when stop is called). Are you
able to rebuild or debug this?

I suspect that one of the work calls is blocking and not interrupting…

Can I ask what version of boost. To make sure this isnt the issue:
