Build fails on Ubuntu 23.10

[bata24]

There are two major errors.

1. enum/integer mismatch

I think this is actually an error that can be ignored.

By predefining export CXXFLAGS="-Wno-error"; export CFLAGS="-Wno-error", the build will proceed to the end.
However, I thought it would be better to report it, so I did so.
