NOTES: * With the latest changes to the CMake build files, as well as the addition of scipy as a runtime requirement, I believe I've found all of the dependencies within GNU Radio whether for building or runtime. GNU Radio should be easy to install and use (for you) and maintain (for me) within the MacPorts environment. If you have any issues when installing via MacPorts please search for the issue https://trac.macports.org/search , and if you don't find it then report the issue in a ticket https://trac.macports.org/newticket ; set the owner as michae...@macports.org. * Please do port variants gnuradio to understand your install options: by default, GNU Radio is installed with only the basic dependencies, which means no SWIG (Python interface), Wx, Qt, GRC, SDL, or the like. I recommend installing via sudo port install gnuradio +full, but I recognize that not everyone wants to wait around for hours while Qt4 is installed; hence, I'm making none of these variants active by default. By popular request this behavior is a change from the past, when everything was installed by default. * For those trying next, I've added a variant for ctrlport as EXPERIMENTAL -- it does not work for me, but maybe it will for you. This variant is not part of +full; you will have to specify it explicitly.

Hi Alexandru - You're welcome! I'm glad to hear from OSX GNU Radio users. Chances are that boost 1.51 is still installed, but not active in MacPorts. You can view all of the installed boost ports via: port installed boost to verify that it's still around. If not, try re-doing my instructions for installing boost 1.51. If it is around, you can try this to make sure boost 1.51 is the active boost: gg=`port installed boost | grep 51 | sed -e s@(active)@@g` sudo port activate $gg If Boost 1.51 is already active, the above will do nothing. If it is not active, it should be made so, an boost 1.52 deactivated (first). Both GNU Radio and UHD work with Boost 1.51, so all you should have to do is (re)activate the older Boost. You can verify which version of Boost is active via: port installed boost | grep active Hope this helps! - MLD ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Title: Scope windows freeze Put a throttle in the flowgraph after your signal source. When you aren't using real hardware as part of a flowgraph, you have to throttle the flowgraph or it will run as fast as possible and consume all available CPU. --n To expand on that, only a *hardware endpoint* or a *throttle* block makes any sample-rate notion actually "real" in the temporal sense. Nearly all of the blocks in Gnu Radio simply use any sample-rate parameter input to calculate internal parameters (for example, when calculating filter coefficients, the sample rate is used to calculate the normalized-equivalent filter from the input parameters). Internal to a flow-graph, Gnu Radio is entirely stream oriented, it has no inherent notions of samples rates -- everything is just a stream of samples that flow past at whatever rate they flow past at, and block functions simply operate on whatever data they get, at whatever times they get that data. The implication of that is that without either a throttle block, or actual hardware to "pace" samples at the expected temporal pace, things will simply run flat-out. Even the signal-source block, which takes a sample-rate input parameter, simply uses that parameter to calculate the internal phase accumulator increments, it makes no attempt to actually supply samples at the desired rate.

As an extension of this document, I am currently completing an extension towards the implementation of some time and frequency analysis algorithms targetted at using GNURadio and the sound card interface as signal generator and acquisition (network analyzer application, frequency counter, phase measurement) for teaching and hobby applications.
