> Subject: [dpdk-dev] [PATCH v10 0/3] pmdinfogen: rewrite in Python
> 
> This patchset implements existing pmdinfogen logic in Python, replaces and
> removes the old code. The goals of rewriting are:
> 
> * easier maintenance by using a more high-level language,
> * simpler build process without host application and libelf,
> * foundation for adding Windows support.

> Identity of generated PMD information is checked by comparing output of

Please see the following build errors:

I also see the exception in Ubuntu 16.04 (Python 3.5.2, pyelftools 0.27), CentOS 7 (Python 3.6.8, pyelftools 0.27), CentOS 8 (Python 3.6.8, pyelftools 0.27) and OpenSUSE Leap 15.2 (Python 3.6.12, pyelftools 0.26).

Thanks,
