Hello Dirk,

Enjoy your vacation!
I just tried to continue with a manual installation of pcre-8.45 instead, and
ran into a different issue that maybe soneone else can shed a light on.
Making StreamDevice (recent git checkout) stops with

---
make[2]: Entering directory
'/home/epics/EPICS/epics-support/StreamDevice/src/O.linux-x86_64'
dbdExpand.pl: No input files for ../O.Common/stream.dbd
dbdExpand.pl: No input files for ../O.Common/stream-base.dbd
dbdExpand.pl: No input files for ../O.Common/stream-scalcout.dbd
make[2]: *** No rule to make target 'stream.dbd.d', needed by 'build'.  Stop.

I just did a bit of surfing through git history and found that this compiles
fine for me up to tag 2.8.20, but breaks with 2.8.21:

---
commit 51e4a0749d3197c1b76b4d38510df18d8ead5359 (tag: 2.8.21)
Author: Ralph Lange <ralph.lange at gmx.de>
Date:   Thu Sep 2 15:54:08 2021 +0200

    make "ifdef CALC" also consider SYNAPPS variable
    
    change the ifdefs to the same expression used in CONFIG_STREAM
---


However, I fail to see why no dbd files are not found anymore now. Any hints
are as always much appreciated.
