[Discuss-gnuradio] Installation issue -gnuradio-companion disable

During installation gnuradio, I encounter this issue. It seems gnuradio-companion is not enable. I found this recommendation though, it is not simple to install cheetah and lxml. Numpy is installed for sure in my VM(Ubuntu 14.04), but not sure of cheetah and lxml. Any advices welcomes Thanks, Ha

Harold, The problem is not cheetah or lxml, the problem is SWIG. It finds version 2.0.11, but rejects it ... the line about "Request SWIG version is at least." is the hint, that line is called when SWIG is found but failed a version check, what's odd is that SWIG_FIND_VERSION is unset... because

Hi Trek, as Martin noted, yes, if you search the GNU Radio source tree for that file name, you'll find it. And also, yes, GNU Radio is Free Software, and one of the main credos of that is that you should be able to use everything from it for your own purposes (as long as you adhere to the freeness

Dear SangHyuk, please be aware that digital receivers aren't really easy to make more CPU efficient; a real-world receiver not only has to convert received symbols to bits, but has to do the frequency and frame synchronization as well as a timing recovery; high-bandwidth transceivers must go throu

Dear Ankit, that is not true. A GNU Radio block is always implemented in C++ or Python. A Block, as you can use it in GRC, is a logical "wrapper" around such a GNU Radio block. To define how that wrapper looks like, you always need to use XML. Hope that explained things well! Best regards, Ma

Hello Steve, that sounds like an interesting project; a couple of friends and I went to the US for GRCON'14, rented a car and somehow Sirius and XM spiked our interest, but as you can imagine, it's kind of hard to receive those in Europe. Could you share a bit of your flowgraph with the community
