Did you disable the Windows firewall, or put the CA exceptions in it?

 

You should be able to remove the :5065 from your EPICS_CA_ADDR_LIST.

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:add

test:pv1

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 :-)
