I cannot get any help information from my octave command prompt.
Example, when I enter
octave:1>help rand
I get the error message
error: fwrite: invalid stream number = -1
error: called from:
error: /usr/share/octave/3.2.3/m/help/makeinfo.m at line 147, column 5
error: /usr/share/octave/3.2.3/m/help/help.m at line 62, column 25
Any idea what the problem could be?
[I am running Ubuntu 10.04 LTS and have installed Octave 3.2 using the Ubuntu Software Center]
short answer: you don’t have write permission in the current directory.
At least on my computer the same error is related to a call to
mkstemp (“octave_help_XXXXXX”, true). Tjis tries to create a temporary file in the current directory and fails.
Try to cd to a writeable directory.
