[USRP-users] Does linking against UHD require linking against boost_thread ?

2020-03-16 Thread Matthias Brändli via USRP-users
Hello all, Could it be that at some point in time, linking against boost_thread became necessary for programs that link against uhd? ODR-DabMod [1] uses pkgconfig to find out how to properly link against libuhd, whose .pc file [2] lists -lboost_system but not -lboost_thread. ODR-DabMod isn't usin

Dear all, I'm maintaining ODR-DabMod[1], a Digital Audio Broadcasting modulator which uses UHD to drive a USRP at 2048ksps, in most applications a B200. ODR-DabMod runs the modulator and the UHD output in separate threads, to ensure that a few modulated frames are always ready when the USRP needs

Hi Felix, the following works for me (newlines added for readability), and I see in the startup messages that it properly sets the master clock rate: /usr/local/lib/uhd/examples/rx_samples_to_file --args "serial=309B1E7,master_clock_rate=32768000" --rate 2048000 --freq 2 --file /dev/n

Dear Felix, I use the B200 to generate DAB signals (OFDM, 2048ksps sample rate, 1.5MHz effective BW, DQPSK) and while I cannot directly answer your questions, maybe there are some pointers that could be useful to you. I did get some feedback from Ettus about spurious signals that I wrote down at
