[Discuss-gnuradio] GR 3.6.1 and OSX

2012-07-10 Thread Ed Criscuolo

Hi Ed - GNU Radio 3.6.1 and the latest trunk will work with OSX 10.5, 10.6, and 10.7; possibly 10.4 though I haven't tested that in a long time. Dependencies are the key, and not an easy set to get installed correctly no matter which path you take to get them (MacPorts, Fink, Homebrew, by hand)

Hi everyone, I just rejuvenated the good old "how to write a block" (see the wiki). That document has been a key component of the documentation for quite a while now, but it was horribly outdated. Now, together with this tutorial[0] and the block coding guide[1] (not to mention the GRC docs, Doxg

Hi I'm trying to add a new module to the USRP's design. My default strategy is to look at the source code and type something up. I was wondering if there was an easy way to quickly plug in a new module. Is there a way that it can be added at a higher level? By high level graphically. Thanks --
