I forgot to include tech-talk in my original reply, but I am including it in this follow-up.

How did you create and build the asyn/exampleAsyn directory?

This output confuses me.  It is generating an error message without echoing the command from st.cmd?

$ ../../bin/windows-x64-mingw/exampleAsyn.exe st.cmd

Invalid directory path, ignored

filename="../dbStatic/dbLexRoutines.c" line number=264

No such file or directory dbRead opening file dbd/exampleAsyn.dbd

Can you please post your st.cmd file?  It looks like it is trying to open dbd/exampleAsyn.dbd, but your default directory is ~/support/asyn/exampleAsyn/iocBoot/iocexampleAsyn, so that path is not valid.  The dbd/ directory is 2 levels above your current default directory.

What is also strange is that in your output it looks like it is starting the IOC twice.  First at the beginning where you get the above message, and then again later where you get this message:

Starting iocInit

checkDatabase: menuConvert not defined.

iocBuild: Aborting, bad database definition (DBD)!

#!../../bin/windows-x64-mingw/exampleAsyn

< envPaths

epicsEnvSet("IOC","iocexampleAsyn")

epicsEnvSet("TOP","/home/ihep/support/asyn/exampleAsyn")

epicsEnvSet("ASYN","/home/ihep/support/asyn/4-39")

epicsEnvSet("EPICS_BASE","/home/ihep/base-7.0.3.1")

Perhaps the problem is in your st.cmd file, and will become clear if you post that.

You should run it in whatever shell you will then run the IOC.

Please send the complete output when you run that command.

 

> ​No such file or directory dbRead opening file /home/ihep/support/asyn/4-39/db/asynRecord.db

 

You are running on Windows, but that file path is using Linux syntax, not Windows.  What shell are you running when you execute the command to run the IOC?  Can you send the envPaths file that was generated in the /iocBoot/iocexampleAsyn directory.

Subject: No PV record found when build ASYN application on Windows

 

Hello everyone,

 

I met two problems when I tried to include asynRecord.db in a windows-x64-mingw EPICS example application. The EPICS base is 7.0.3.1 and asyn is 4-39.

 

I have specified the EPICS_BASE and ASYN paths in the configure/RELEASE file. And I have added exampleAsyn_LIBS += asyn, exampleAsyn_DBD+=asyn.dbd and exampleAsyn_DBD+=drvAsynIPPort.dbd into src/Makefile. No error was printed while 'make clean install'. However,

 

1) st.cmd could not work. It said:

$ ../../bin/windows-x64-mingw/exampleAsyn.exe st.cmd

C:/msys64/home/ihep/support/asyn/exampleAsyn/bin/windows-x64-mingw/exampleAsyn.exe: error while loading shared libraries: exampleAsynSupport.dll: cannot open shared object file: No such file or directory

I followed the solution mentioned here, https://epics.anl.gov/tech-talk/2017/msg00009.php, adding the path of asyn.dll to variable PATH. IOC could finally run. I saw Mr. Rivers gave another better way to do that(https://epics.anl.gov/tech-talk/2017/msg00013.php). Should I run the bat file in Windows command prompt or MingGW?

 

2) Though the IOC was started, there was no pv record.

$ ../../bin/windows-x64-mingw/exampleAsyn.exe st.cmd

I could find exampleAsyn.dbd in dbd/ directory.

 

I built a same example application on Linux(base 3.15.6, asyn 4-33), and it succeeded. Could someone please help me with this? Thanks a lot.
