python3
from cffi import FFI _ffi = FFI() _ffi.cdef(""" ... int rpmvercmp (const char a, const char b); ... """) warning：yacc table file version is out of date。 以上命令可复现warning。
不报警告版本： rpm -qa|grep -E "python3-ply|python3-pycparser" python3-ply-3.9-9.ky10.noarch python3-pycparser-2.20-2.ky10.noarch
python3
import ply ply.version '3.9'
grep tabversion /usr/lib/python3.7/site-packages/pycparser/yacctab.py _tabversion = '3.8' //这个版本是正常的，上面的version=3.9，这里的_tabversion=3.8，与下面的版本对上，所以不报警告。
grep "version" /usr/lib/python3.7/site-packages/ply/yacc.py version = '3.9' tabversion__ = '3.8'

grep tabversion /usr/lib/python3.7/site-packages/pycparser/yacctab.py _tabversion = '3.8' //这里的版本过低导致报warning，上面的version=3.11，这里的_tabversion=3.8，与下面的两个版本对不上，所以报警告。
grep "version" /usr/lib/python3.7/site-packages/ply/yacc.py version = '3.11' tabversion__ = '3.10'
