Command line interface (CLI) and EPMacro
I came across another issue with the command line interface of EnergyPlus version 9.0.1. This issue seems to be different from the one reported here https://github.com/NREL/EnergyPlus/is....
Running the attached file using the CLI on Windows and Linux shows different behavior.
On Windows 10, when I run
energyplus -w D:\EnergyPlusV9-0-1\WeatherData\USA_CA_San.Francisco.Intl.AP.724940_TMY3.epw -p "Test" -s C -x -m -r _fmu-export-schedule_no_ext.idf
EnergyPlus will complete successfully.
On Linux (Ubuntu), when I run (the same command as in Windows)
energyplus -w /usr/local/EnergyPlus-9-0-1/WeatherData/USA_CA_San.Francisco.Intl.AP.724940_TMY3.epw -p "Test" -s C -x -m -r _fmu-export-schedule_no_ext.idf
EnergyPlus will crash with following stack trace:

Any hints?
P.S. The IDF file can be downloaded from C:\fakepath_fmu-export-schedule_no_ext.idf.jpg (After download, please rename the file to _fmu-export-schedule_no_ext.idf).
P.P.S. The path to the Weather file needs to be adjusted to run the command.
This issue affects EnergyPlus models which are exported as FMUs.
For both Windows and Linux, the CLI links the idf path to the current-working-directory/in.imf. From the error message, EPMacro is not finding that file. Is the idf located in the Scripts directory? If not, you may need to use a full path to the idf on the EnergyPlus command line.
The IDF file is in the Scripts folder. The command works fine on Windows but not on Linux so I don't think that it is a path issue.
Not sure what else it could be, the CLI code is the same for Windows and Linux unless you happen to be using Win32 exe. I wonder if EPMacro is assuming an extension of imf. Can you try that?
But that would be the same on Windows - file extension.
Yes, I would have expected the same behavior on both systems (I am on a Windows 64 bit machine). Maybe someone with a Linux machine can try and see if he can reproduce.
