EPICS 7.0.4.1. Gettings Started under Windows 10 WSYS2 MinGW UCRT 64, Problem with camonitor

[Alexander Kessler via Tech-talk <tech-talk at aps.anl.gov>]

Dear Community,

    I am new to EPICS and need some  start up help.
    
    I have compiled EPICS 7.0.4.1 following these instructions:
https://docs.epics-controls.org/projects/how-tos/en/latest/getting-started/installation-windows-msys2.html
    under Windows 10 MSYS2 MinGW.

After that I have build the test application. I work in the MSYS2 shell. When I start the TestIOC I get the following output:

$ ../../bin/windows-x64-mingw/test st.cmd
#!../../bin/windows-x64-mingw/test
< envPaths
epicsEnvSet("IOC","ioctest")
epicsEnvSet("TOP","C:/Users/AlexK/work/epics/testioc")
cd "C:/Users/AlexK/work/epics/testioc"
## Register all support components
dbLoadDatabase "dbd/test.dbd"
test_registerRecordDeviceDriver pdbbase
Warning: IOC is booting with TOP = "C:/Users/AlexK/work/epics/testioc"
          but was built with TOP = "/c/Users/AlexK/work/epics/testioc"
## Load record instances
dbLoadRecords("db/test.db","user=AlexK")
cd "C:/Users/AlexK/work/epics/testioc/iocBoot/ioctest"

test:pv2

So far so good. When I clone the shell session with mintty & and start camonitor, I get:

$ camonitor.exe test:add
test:add                       *** Not connected (PV not found)
CAC: Unable to connect because "WINSOCK Error 10051"
CA.Client.Exception...............................................
    Warning: "Virtual circuit disconnect"

    Source File: ../cac.cpp line 1237
    Current Time: Mon May 08 2023 20:59:00.391220265

So I wanted to get rid of the warnings about duplicate addresses. I have tried to set the environment variables EPICS_CA_AUTO_ADDR_LIST and EPICS_CA_ADDR_LIST in various ways. Among others, in the testioc\iocBoot\ioctest\envPaths with epicsEnvSet() , and in the shell with export and setx commands. But no matter what I do, the behaviour does not change.

My dev PC has two ethernet cards. The second one has multiple IP4 addresses for communication with lab network and local test equipment.

The set of EPICS env. variables looks like this:

$ printenv | grep EPICS
EPICS_CA_ADDR_LIST=192.168.50.222:5065
EPICS_HOST_ARCH=windows-x64-mingw
EPICS_CA_AUTO_ADDR_LIST=NO
EPICS_BASE=C:\Users\AlexK\work\epics\base-R7.0.4.1

 I think I am close to the target, but somewhere I have a thinking error. I assume this is related to the handling of the environment variables in MSYS2 Shell and EPICS.

Best wishes and thank for reading this long e-mail :-)
