That program was developed by Michael Davidsaver at NSLS-2 many years ago. How do you load you *.db file in your st.cmd? You need a ‘bo’ record similar to this:

Subject: Trying to use elauncher: _main_ thread failed

 

I don't see much documentation about what we call 'elauncher' here, so I'm thinking it might be something site specific? In any case, It's what we use to add PVs that trigger python scripts to our IOCs. I've attached the source code we add to our src/ folder. We also have an elaunchSupport.dbd file that simply contains two lines 'device(bo, INST_IO, devLauncher, "Launcher")'' and 'variable(launcherVerbose, int)'.

 

I'm getting an error when attempting to start the IOC, and I'm wondering if someone here could enlighten me as to the problem:

 

```

A call to 'assert(prec->out.type == INST_IO)' by thread '_main_' failed in ../launcher.c line 80.

Dumping a stack trace of thread '_main_':
