Ali, given that you haven't received any responses so far, I guess this means there are not so many people out there who are willing to share their images ;) It might be useful to create such an image, but in the free software world, you're more likely to find people using KVM or Xen instead

Let me put it this way... I'm going to build it because I need it ;) But what I'm asking/hoping for is for it to be useful beyond just me and actually have a lifespan beyond my immediate use of it. So, I'd like to get some feedback on how others might like to see it tied in to UHD, or the type of

[Discuss-gnuradio] cmake destination on 64-bit machines

2012-03-04 Thread John Coppens
Hello all, Cmake seems to insist on installing all libraries in /usr/local/lib instead on /usr/local/lib64. I can't find an obvious way to define a destination path in cmake, or an architecture. My machine is an AMD64, running Slackware, where the difference between 32 and 64 bit libraries is def

In the amateur radio world, AX.25 "packet radio" terminal node controllers supported KISS mode, which left the CSMA and HDLC framing in the TNC but offloaded the state-machine for connection management to the host CPU stack. KISS merely provided a way to forward the frame metadata and payload ov

Definitely, there are MACs whose form of carrier sense is detecting preamble rather than detecting energy. In my same piece of work, we put a matched filter in the FPGA and the host specifies the coefficients of the match filter, then you gate on that. But, I don't think it's unreasonable t

It looks like you have a mixed install, somehow, of MacPorts stuff; some older, some newer. If you haven't done it recently, I'd recommend: sudo port selfupdate sudo port upgrade outdated and, if that breaks, do: sudo port clean outdated sudo port -p upgrade outdated and then report the issue
