Hello,
I am trying to cross-compile UHD on an E320 with the OE SDK, but I cannot get
past the cmake step due to multiple errors. On the host PC, I am able to
install the SDK and source the environment variable without issues. When I go
to build UHD, the first error is that the CMakeLists.txt file for UHD 3.15 has
a minimum CMake version of 3.5.1, but the OE SDK cmake is version 2.8.12.2 (my
host PC is version 3.18.4). I manually edited the CMakeLists.txt to accept the
older version of CMake, but then it has a boost version error and cannot find
several python packages (platform, mako, requests, numpy). I again edited it
for the Boost version, but it still can't find the python packages. Do I need
to somehow install all the UHD dependencies in the OE SDK paths after
installing it? Or am I doing something else wrong?
I also tried running "import sys" to see the Python path configuration and the
"program name", "sys._base_executable", and "sys.executable" are all pointing
to "/usr/bin/python3" instead of the "/home/~/oe/sysroots/x86_64-oesdk-linux"
path. Not sure if that's part of the problem or not, but it seemed suspicious.
The cmake and import sys outputs are copied below.
