Hello Dirk,

Unfortunately, we cannot get your pcre2 branch to compile, it fails with

---

dbdExpand.pl: No input files for ../O.Common/stream.dbd
dbdExpand.pl: No input files for ../O.Common/stream-base.dbd

Is there anything obvious we are overlooking? We can get a bit further using
https://github.com/daykin/StreamDevice/commits/pcre2

However, this only compiles up to base tag R7.0.9, but it will fail with
R7.0.10. Is there any recommendation on how to proceed? Is there already an
ETA for "official" pcre2 support in StreamDevice? Alternatively, we might
also fall back to a manually installed pcre3 for the time being.
