I downloaded again and checked MD5 hash, but the same "errors" come out during cmake. Since configurations is done as well as build files written to appropriate folder, does that means that these errors are not serious? io.h file is for example located in /usr/include/sys/io.h (is that like at your

I updated the MacPorts install for GNU Radio to reflect the new 3.7.0 release and changes to the master and next branches. Here are the new ports (and, some related): - gnuradio-legacy: the latest 3.6.5 release (currently 3.6.5.1). - gnuradio: the current release (3.7.0 right now). - gnuradio

Re: [Discuss-gnuradio] Trouble building stuff with build-gnuradio

2013-07-02 Thread Tim O'Shea
I'm not sure its the job of a build system to clean up the broken state left by either not running uninstall previously or an incomplete uninstall routine - this strikes me as a bit of a hackish solution to a more general problem Rather than worry about this I would like to see people who build GNU

There are currently two fading model blocks that are usable in 3.7 both should show up in GRC - or from python you can use: the flat fading model: channels.fading_model( 8, 10.0/samp_rate, False, 4.0, 0 ) where args are {# sinusoids, fDTs, los_component, rician_factor, prng_seed } and a s

[Discuss-gnuradio] Static compilation of GNU radio

2013-07-02 Thread John Wilson
Hey guys, I wonder whether anyone has done this before/can help me out. I'm looking to compile GNURadio with all static libraries, so that there are zero .so dependencies. I've been playing around with CMake, but it looks like the linker order is wrong for compiling against static libraries: What

Hello everyone, Quick update on the London meetup next week. I still haven't identified a location (had one; fell through; looking for another spot). Please let me know (if you haven't already) if you'll be joining me so I can find a place appropriate for the size. What I do know is that it will

[Discuss-gnuradio] simple_ra updated to include pulsar processing

2013-07-02 Thread Marcus D. Leech
The latest simple_ra includes pulsar processing support, although very few amateurs will have an antenna big enough to do any pulsar work, it turns out, because of the fractional resampler, to have been relatively easy to support. simple_ra now relies on the gr-ra_blocks OOT module. So, you'

Ø The associated mutex is usually a (private) member variable of a class, and is used as a synchronization object by different class methods. As a member variable, you have a choice to name it whatever you want. If the mutex is the only one in the class, we usually call it d_mutex. If there
