[Octave-bug-tracker] [bug #51632] MS Windows portable (i.e. zip) version cannot find pre-installed packages, needs pkg rebuild, not mentioned at first run

[Nicholas Jankowski]

Follow-up Comment #9, bug #51632 (project octave):

ok. must be more to this.  


>> fullfile(OCTAVE_HOME (), "\share\octave\packages\signal-1.3.2")
ans = C:\Octave\OCTAVE~1.1\shareoctavepackagessignal-1.3.2

but put within the octave_packages, it produces:


Package Name  | Version | Installation directory
--------------+---------+-----------------------
      signal  |   1.3.2 | ...\share\octave\packages\signal


trying the long version of fullfile:


>> fullfile(OCTAVE_HOME(), "share", "octave", "packages", "signal-1.3.2")
ans = C:\Octave\OCTAVE~1.1\share\octave\packages\signal-1.3.2


but using that in octave_packages:

>> pkg list signal
Package Name  | Version | Installation directory
--------------+---------+-----------------------
      signal  |   1.3.2 | ...ile(OCTAVE_HOME(), "share", "octave",
"packages",


it doesn't check for a valid path:

C:\Octave\OCTAVE~1.1\share\octave\packages123\signal-1.3.2


>> pkg list signal
Package Name  | Version | Installation directory
--------------+---------+-----------------------
      signal  |   1.3.2 | ...\OCTAVE~1.1\share\octave\packages123\signal-1.

>> pkgtest{1}.dir
ans = C:\Octave\OCTAVE~1.1\share\octave\packages123\signal-1.


but if I make it something arbitrarily short:

C:\Octave\OCTAVE~1.1\share\signal-1.3.2

>> pkg list signal
package signal is not installed.


so... haven't yet figured out how to be sure it's actually storing/reading the
correct folder, and whether the truncation is just a display thing or if it's
actually stored incorrectly.


so, not quite sure it'll work, and something about how octave_packages is read
seems to 'sometimes' truncate things. eg:


>> pkgtest = pkg("list","signal");
>> pkgtest{1}.dir
ans = C:\Octave\OCTAVE~1.1\share\octave\packages\signal-1.3.2
>> pkgtest{1}.archprefix
ans = C:\Octave\OCTAVE~1.1\share\octave\packages\signal-1.3


despite the location being the same in the text file.
