[Octave-bug-tracker] [bug #40381] MXE / MinGW - setenv does not work correctly

[Philip Nienhuis]

Follow-up Comment #19, bug #40381 (project octave):

Thanks.

I just tried the tip 17784:7ae9bc04ec07  (MXE cross build on WinXP)

1. When closing octave (CLI and GUI), I now see an error message flashing by:

>> error: permission denied
error: ignoring octave_execute_exception while preparing exit


(Text could be a little different as it shows maybe 0.25 sec before the Octave
windows disappears).

2. When starting octave.exe, I get the CLI; with or without the --force-gui
flag makes no difference.
I need to explicitly start octave-gui.exe to start the GUI.
>From the post you referred to I can't figure out whether that is the intended
behavior (but OK it is bed time here).

Starting octave-gui with --no-gui flag makes octave-cli start.

Please interpret the following just as a report. If it is like you expect,
good, please ignore.

Starting Octave from a cmd32 command prompt ("Windows shell") gives funny
results:

X:\Octave\octave-2013-10-28-22-49\bin>octave
    <6 seconds wait ....>
X:\Octave\octave-2013-10-28-22-49\bin>GNU Octave, version 3.7.7+

... so once octave is started, hitting the Enter key switches between the
cmd32 terminal and the Octave prompt. Although / while an octave prompt is
displayed, it doesn't seem that octave accepts octave commands.

Now, running octave-cli from a command prompt behaves as expected:

X:\Octave\octave-2013-10-28-22-49\bin>octave-cli

Same goes for octave-gui.exe, only the error message is shown in the terminal
pane.
