instructions for building bcc on Debian 10

[mmelo-yottaa]

I am trying to use bcc python bindings on Debian 10 with v5.8.5 kernel I built. Using the apt-install Debian 10 bcc package I get this failure:

mike@debian$ python bindtrace.py

From reading #2573 it seems I might be well off building a new bcc. This was not easy, I uninstalled Debian 10 LLVM/clang and installed version 3.8 from Debian 9 (stretch) to match the instructions here:

https://github.com/iovisor/bcc/blob/master/INSTALL.md#debian---source

There were issues using newer Debian 10 LLVM/clang versions, lots of warnings during build, also errors and failed tests.

After down-rev'ing LLVM/clang, and installing all other prerequisites per the above URL, the build completed but a large number of tests fail. I can forward bcc_0.16.0-1_amd64.build if that is interesting.

Could you please point me at instructions for building bcc on Debian 10 that work? I can up-rev or down-rev installed components at necessary, although I prefer to use latest bcc / kernel / buildtools.

Thank you.

it sounds a duplicate of #3081
