Anyone can help with this compiler error? Never seen it before...

Maybe it's because compile with `-fno-rtti`?

I removed -fno-rtti when linking still the same error. Or I also need to ensure when librocksdb.a is compiled, it also doesn't have -fno-rtti?

What has changed? I looked at the default makefile in Rocksdb, it seems always set -fno-rtti and it worked fine before....

Not sure. If this is broken recently, then we should fix it.

Can you help by doing a make clean and then make? If it still fails after a clean, feel free to open a Github issue with steps to repro. Thanks!
