Hi Folks, I would like to interface my Raspberry Pi 4 to a USRP B210 via the Python API. This requires the UHD driver to be built from source. Unfortunately, whenever I try this I encounter some errors that stop the build process in its tracks.
Details of the error are as follows: [ 53%] Linking CXX executable test_clock_synch /usr/bin/ld: ../lib/libuhd.so.4.0.0: undefined reference to `__atomic_compare_exchange_8' /usr/bin/ld: ../lib/libuhd.so.4.0.0: undefined reference to `__atomic_load_8' /usr/bin/ld: ../lib/libuhd.so.4.0.0: undefined reference to `__atomic_store_8' /usr/bin/ld: ../lib/libuhd.so.4.0.0: undefined reference to `__atomic_fetch_add_8' collect2: error: ld returned 1 exit status make[2]: *** [examples/CMakeFiles/test_clock_synch.dir/build.make:95: examples/test_clock_synch] Error 1 make[1]: *** [CMakeFiles/Makefile2:1039: examples/CMakeFiles/test_clock_synch.dir/all] Error 2 make: *** [Makefile:163: all] Error 2 The process I have been using is as follows: STEP 1: INSTALL DEPENDENCIES sudo apt-get install libboost-all-dev libusb-1.0-0-dev doxygen python3-docutils python3-mako python3-numpy python3-requests python3-ruamel.yaml python3-setuptools cmake build-essential STEP 2: BUILD UHD DRIVER FROM SOURCE cd /home/pi mkdir workarea-uhd cd workarea-uhd git clone https://github.com/EttusResearch/uhd cd uhd git checkout v4.0.0.0 cd host mkdir build cd build sudo cmake -DNEON_SIMD_ENABLE=OFF -DENABLE_PYTHON_API=ON ../ sudo make ---> (ERRORS OCCUR DURING "MAKE" PROCESS) My system configuration is as follows: Hardware: Raspberry Pi 4 Model B Rev 1.4 OS: Raspbian GNU/Linux 10 (buster) (32-bit, armv7l) Ettus USRP B210 Does anyone know what the problem could be, and how I can resolve it? One final note: Using PyBOMBS, I was able to successfully build & install the UHD driver and connect to the USRP. Unfortunately the PyBOMBS build does not include the Python API, which is what I really want. Is there a different version of the PyBOMBS build that includes the Python API? Thanks & Regards, Brendan.
