I can successfully compile in Ubuntu 20.04, but the compiled result cannot run on Ubuntu 18.04 and reports the following error:
/sysdig: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by ./sysdig)
./sysdig: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by ./sysdig)
I have checked your released binary files, and it seems that they were also compiled with g++-9, but your binaries can run on lower versions of Linux systems (I tested on Ubuntu 16.04). Can you share some information about the compilation environment? I found that the documentation's requirements for gcc and cmake may not be very accurate; at least in my experience, I need cmake version 3.12 or higher and g++-9 or higher to compile successfully.
I built the docker image named sysdig-builder under the docker/builder directory and used this image for compilation. My compilation steps are as follows：
docker run -v $PWD/..:/source -v $PWD/build:/build sysdig/sysdig-builder cmake
docker run -v $PWD/..:/source -v $PWD/build:/build sysdig/sysdig-builder sysdig

The bpf_probe.skel.h is related to the modern probe (that doesn't support your kernel). You can just disable it doing cmake -DBUILD_SYSDIG_MODERN_BPF=OFF and you should be ok :)
