I can conform this on Windows 7 and there are some interesting observations:

  1. As in the original post, saving and running a file, e.g. as "ccc.m" leads to "error: 'ccc' undefined near line 1, column 1" although the file exists
  2. Following comands "ccc" in the console lead to the same error
  3. "run('ccc') does not work
  4. "source('ccc.m')" works
  5. "edit ccc" works
  6. Adding the path of the offline network share explicitly to Octave's task solves the problem
  7. The problem does not occurr when the file is already existing when octave starts
  8. All this is not GUI-related and also happens in the CLI

It seems that Octave is not able to handle the current directory as a member of the search path if it is on offline network share. Changing category from GUI to Interpreter.

My configuration:
OS: Windows 10
Octave version: 5.1.0
Network drive mounted on "Z:"
A folder in "Z:" has been marked in Windows as "Always available offline"
Network disconnected (i.e. working on the "offline" copy)

Steps to reproduce:

  1. Open Octave GUI
  2. Use the 'File Browser' to navigate to a folder on the cached network drive ("Z:" for me). This folder should already have ".m" files to run (that were created before opening Octave).
  3. Open one of those files in the editor and "Save File and Run" icon. (This should run fine)
  4. Go to editor tab
  5. Click "New File" icon
  6. Write any Octave code in the blank file (e.g. my_var=20;)
  7. Click "Save File and Run" icon and save as 'my_new_file.m' in the current directory (network drive)

After above steps, in the command window, the following error is displayed:

error: 'my_new_file' undefined near line 1 column 1

The file is correctly displayed in the Octave File browser.

When I close and re-open Octave GUI and navigate to the folder again, I am able to run the file.

This seems to only be a problem with cached network mounted drives (I cannot reproduce the same problem when I follow above steps in any folder in my C: drive or when I do it in an "online" network mounted drive)
