OMOptim does not communicate with OMC

[daniel.fischer@…]

I have posted the issue below on Stackoverflow 2 weeks ago. I am not sure if this is the formal way to post a bug, and see if anyone is/will work on it. I am running Win 7. Using Task Manager/Processes I can see OMOptim.exe is running and omc.exe was also stated by OMOptim, so I suspect the issue is OMOptim does not see info. from omc.

Here's my original post.

I am trying to use OMOptim within OpenModelica. When starting OMOptim, it took it a considerable amount of time to put the canvas on; once it was on, I looked in the Message Output (under Log/MO) and found the message OMC not started. Please start it again (menu OMC->restart). I try Tools/OMC/start omc and just like the previous post, I get:

08:43:31] OMC not started. Please start it again (menu OMC->restart)
[08:57:34] OMC: unable to find OMC server, Object reference file C:/Users/Daniel/AppData/Local/Temp/OpenModelica/OMOptim//openmodelica.objid.OMOptim{E5F24F12-CB25-40B3-81BD-255279DBC379}085713394 not created.

Of course trying to load a model into OMOptim fails with complaint that omc is not running.

Can you see if the file C:/Users/Daniel/AppData/Local/Temp/OpenModelica/OMOptim//openmodelica.objid.OMOptim{E5F24F12-CB25-40B3-81BD-255279DBC379}085713394 is created? (Note that next time you start OMOptim a new file is generated.)

Also attach the files OMLog.txt and openmodelica.omc.output.OMOptim.

OMLog.txt

I am trying to attach, but apparently I am spam.... and whatever I type is not good enough for the spam filter...

Please let me know if you can use this info, else I will keep fighting to upload the files.

Thank you for your efforts.

Can you also check if object reference file is created in the directory or not?

I think I fixed this with: 72a076/OMCompiler ​https://github.com/OpenModelica/OMCompiler/pull/1741
right after you reported it on StackOverflow but didn't had time to test it.
The Corba file was not created in the given path, but directly in the temp directory.

Have you tried with the latest nightly-builds? As far as I can see you are still using alpha1
​https://build.openmodelica.org/omc/builds/windows/nightly-builds/

I tested it now and it seems to be working.

Still appears to be defective on Linux (Lubuntu 16.04). I compiled OMOptim from the GitHub repo today.

OMC: unable to find OMC server, Object reference file /tmp/OpenModelica_pesimon/OMOptimopenmodelica.objid.OMOptim123622265 not created.

The specified file exists in the directory.

I have the same problem, may you please detail the steps you made to correct this error?
