that or you would have to write an OOT GNU Radio module (or perhaps someone
already did, I am not sure).

At the moment there are only two in-tree kernel drivers, one for the

Hello,
I've got a flowgraph with one source that will end in several sinks. Not
all paths of the flowgraph are needed all the time and I would like to
enable/disable a path without stopping the flowgraph to reduce processor
load.
When I leave a path unconnected by default the application will cras

I just got the latest git version of gnuradio and tried to compile, but
I get compilation errors resulting from avxintrin.h:
http://pastebin.com/uq4uGeNs
These errors seems to be common and result from using non-standard
GCC-extensions that clang does not support.
Any ideas?

Unfortunately I do not have any other hardware than two different RTL
devices (one with E4000 tuner and one with R820T).
I attached the most simple program to reproduce that error, it just
connects the OsmoSDR source with a null sink, starts the flowgraph,
waits a second and then stops it and exit.
probably a bit too much.
Thanks

Hi,
my C++ program is already working great, except one major bug on OS X:
I cannot stop the flowgraph: When I call on the top block:
gr_tb->stop();
gr_tb->wait();
It will hang on the wait. That means the program cannot quit nicely, but
will always crash at exit. It´s working fine on Linux and W

Confirmed it´s the allocator:
Recompiling with other allocation engine removed did not work.
Removed my hack and compiled with posix_memalign: Stable.
Thank you very much

Yes, it´s OS X 10.9, but I think I compiled with 10.7 compatibility,
will check what happens when I recompile with the other allocation
engine removed.

I want my program to be platform independent (it should work on Linux,

Although it runs stable on Linux (Xubuntu 14.04 amd64), on both Windows
(Win 7 x64) and OS X (10.9) it´s crashing after about a minute.
For OS X I followed the build guide provided (installed using por
