I have cross-compiled UHD v3.15.0.0 and gnuradio maint-3.8 for the E310. When I try to setup the cross-compile of gr-ettus maint-3.8, I get a series of errors related to SWIG. Any idea how to work around this? My cmake command is: cmake -DCMAKE_TOOLCHAIN_FILE=~/rfnoc/src/gnuradio/cmake/Toolchains/oe-sdk_cross.cmake -DCMAKE_INSTALL_PREFIX=/usr .. And here are the errors:
