Does not compile on BeagleBone Black

[nmingotti]

Hi,

I am trying to compile sysdig on the BeagleBone Black since the Debian package is quite far from working.

My system is:

$> uname -a
Linux beaglebone 4.14.108-ti-r113 #1 SMP PREEMPT Wed Jul 31 00:01:10 UTC 2019 armv7l GNU/Linux

The error message I see I few hours after make starts is this:

[ 88%] Building CXX object userspace/libsinsp/CMakeFiles/sinsp.dir/runc.cpp.o
[ 89%] Building CXX object userspace/libsinsp/CMakeFiles/sinsp.dir/cgroup_limits.cpp.o

Can you tell me how to fix it ? I would really like to try sysdig.

Hi @nmingotti. There's no formal ARM support, and I don't know if or when that will ever change. However, you're welcome to submit patches yourself so that it builds! We have recently begun building for ppc64 and s390x, so the dream of a cross-platform sysdig may not be as farfetched as it seems.

Duplicate of https://github.com/draios/sysdig/issues/1617, which has a solution.

@nmingotti can you validate that the latest source will build on your system?

Closing as this bug was addressed by @kris-nova in https://github.com/draios/sysdig/pull/1622

This should fix the issue mentioned above. Like I said in the issue I tested on a few of the cortex raspberry pi boards.

Please do share your findings on the beaglebone as I am starting to document a lot of sysdig on arm as an unofficial resource for the community.

Thanks all!

Thank you Kris!
