It looks to me like this changeset was pushed to the repository 6 months ago:


Closing this report as fixed.

Trying to understand what was wrong,
I found the code for checking versions
in pkg.m was overly complicated and could
be simplified and made more robust.

With the attached changeset the fpl DESCRIPTION
does not cause errors when installing.

Can you please test it a bit?

I believe this is a symptom of a problem in Octave
as it used to work correctly in the default branch
and in the development branch until last week.

anyway as a workaround I removed the spaces from
fpl/DESCRPTION in the repository.

I don't see it as urgent to update the package release
as this only affects development branch.

A fpl package from the repository is attached below for your convenience.

This bug should be fixed fast, just two spaces too much in the DESCRIPTION file.

octave:1> pkg install -forge fpl
incorrect syntax for dependency 'octave ( >= 3.2.3 )' in the DESCRIPTION file
error: called from 'fix_depends' in file /usr/local/share/octave/3.7.5/m/pkg/private/fix_depends.m near line 44, column 9
error: called from:
error:   /usr/local/share/octave/3.7.5/m/pkg/private/install.m at line 147, column 5
error:   /usr/local/share/octave/3.7.5/m/pkg/pkg.m at line 392, column 9

When you try the parsing separately one can easily see the problem:

octave:9> fix_depends('octave (>= 3.2.3)')
ans =
  [1,1] =

    scalar structure containing the fields:

      package = octave
      operator = >=
      version = 3.2.3

octave:10> fix_depends('octave ( >= 3.2.3 )')
error: incorrect syntax for dependency 'octave ( >= 3.2.3 )' in the DESCRIPTION file

An alternative to changing the DESCRIPTION file would be changing the behavior of Octaves "/scripts/pkg/private/fix_depends.m"
