[Discuss-gnuradio] [UHD] Python API

2018-06-20 Thread Martin Braun
Hi all, after a while of testing and gathering feedback, we have merged the UHD Python API into master branch. In general, we are happy with its state, but that doesn't mean it's perfect and complete. First off, there's at least one known issue with the Python API: It does not build on Windows.

I'd suggest incorporating RFNOC at least as an option. I suspect actual use of DVBS2X might be rather boring if you're stuck on a processor. On Wed, Jun 20, 2018 at 4:38 PM Michelle Thompson < mountain.miche...@gmail.com> wrote: > Hello everyone, > > GNU Radio Conference is coming up in

Yay, it works! Thank you, Basti and Marcus :) So the only change I needed to make for my build system is to find the first target_link_libraries() under lib/CMakeLists.txt and add both ${GNURADIO_ALL_LIBRARIES} and uhd to the list (both are required). I did not have to add anything to the link

Basti applied hammer to nail's head. It's (probably) super effective. yeah... time_spec_t's functions aren't exported symbols of libgnuradio- uhd, but of libuhd! This might work on some and not on other build systems due to different handling of visibility of symbols *used* in a library. uff! On

That's normal FIFO behaviour! From `man 3 mkfifo`: > Opening a FIFO for reading normally blocks until some other process opens the same FIFO for writing, and vice versa. Remember, the GRC file is just converted to a Python program, in which the different blocks are instantiated sequentially.

Re: [Discuss-gnuradio] Error Linking UHD

2018-06-20 Thread Bastian Bloessl
Any chances you are confusing libgnuradio-uhd.so with libuhd.so. To me it sounds like you want to link against the latter. Maybe some linkers resolve symbols from libuhd through libgnuradio-uhd and some don't (which might make sense if you do not use any symbols defined in libgnuradio-uhd).
