Thanks a lot for your answer. We need fully statically application, because we want to run it on device with older kernel, than building one.

Regards,
Michael

This is not something we have ever looked to do with DPDK builds. Normally, we consider static builds to be builds where we link in all the DPDK libraries statically, but don't consider OS-libs for static linking. Is there a particular reason why you need a fully-static version of the code - can you compile and run on the same system, or build on a system with the same OS version as you intend running the code on?
