This is good information and helped me out with my cross-compiler issues. So, for posterity, my setup is as follows: 1. Ubuntu 18.04LTS 2. UHD4.0 (gitbranch UHD-4.0) 3. GNU Radio (gitbranch maint-3.8) 4. gr-ettus (gitbranch maint-3.8-uhd4.0) These were installed on the host using pybombs with the recipe modified for the branches listed previously. Next, I downloaded the SDK with "uhd_images_downloader -t e310 -t sdk" and installed into a new cross compile directory (~/prefix/gr38/oe) Next, I added python-six and added the following PYTHONPATH line in the script that sources the cross-compiling environment variables: export PYTHONPATH=/home/mike/prefix/gr38/oe/sysroots/cortexa9t2hf-neon-oe-linux-gnueabi/usr/lib/python3.7/site-packages/:$PYTHONPATH Note: this is in addition to what was previously instructed which was: export PYTHONPATH=/home/mike/prefix/gr38/oe/sysroots/x86_64-oesdk-linux/usr/lib/python2.7/site-packages/ Bottom line is to inspect the output of gnuradio cmake to ensure that all python related items are found properly For cross compiling I used the following cmake directives for each item 1. UHD4.0 - cmake -DCMAKE_TOOLCHAIN_FILE=../host/cmake/Toolchains/oe-sdk_cross.cmake -DCMAKE_INSTALL_PREFIX=/usr -DENABLE_E300=ON -DENABLE_GPSD=ON .. Note: I tried this with setting -DRUNTIME_PYTHON_EXECUTABLE=python2 but it did not compile 2. GNU Radio - cmake -Wno-dev -DPYTHON_EXECUTABLE=/usr/bin/python2 -DCMAKE_TOOLCHAIN_FILE=~/prefix/gr38/src/gnuradio/cmake/Toolchains/oe-sdk_cross.cmake -DENABLE_INTERNAL_VOLK=OFF -DENABLE_GR_WXGUI=OFF -DENABLE_GR_VOCODER=OFF -DENABLE_GR_DTV=OFF -DENABLE_GR_ATSC=OFF -DENABLE_DOXYGEN=OFF -DCMAKE_ASM_COMPILER_ARG1:STRING="-mcpu=cortex-a9" -DCMAKE_INSTALL_PREFIX=/usr ../ Big point here is -DPYTHON_EXECUTABLE=/usr/bin/python2 3. gr-ettus - cmake -DCMAKE_TOOLCHAIN_FILE=~/prefix/gr38/src/gnuradio/cmake/Toolchains/oe-sdk_cross.cmake -DCMAKE_INSTALL_PREFIX=/usr -DENABLE_QT=OFF -DENABLE_DOXYGEN=OFF .. Linus seems to be a moving target so what works one day may not work the next. That's why I try to document what configuration worked for me.
