Makefiles are adjusted.\n3. f-strings replaced with % formatting to support Python 3.5.\n4. Wrapper script does not hide stderr from ar and pmdinfogen.\n\nOnly logic errors, like missing symbols or invalid content, are checked.\nThis seems enough for debugging and, to my understanding, there are no\nstrong objections. All errors raise exceptions printed to stderr.\n\nWhile discussion of future wrapper logic and Windows support continues,\nthis patchset is ready for testing and review.\n\nDmitry Kozlyuk (3):\n pmdinfogen: prototype in Python\n build: use Python pmdinfogen\n doc/linux_gsg: require pyelftools for pmdinfogen\n\n GNUmakefile | 2 +-\n buildtools/Makefile | 9 --\n buildtools/gen-pmdinfo-cfile.sh | 3 +-\n buildtools/meson.build | 3 +-\n buildtools/pmdinfogen.py | 191 ++++++++++++++++++++++++++++++\n doc/guides/linux_gsg/sys_reqs.rst | 6 +\n drivers/meson.build | 2 +-\n mk/internal/rte.compile-pre.mk | 2 +-\n mk/rte.sdkinstall.mk | 2 -\n 9 files changed, 202 insertions(+), 18 deletions(-)\n delete mode 100644 buildtools/Makefile\n create mode 100755 buildtools/pmdinfogen.py" }
