(Updating time-spent)

octave-2.1.50-2.i386.rpm gives the following error: octave:2> help -i sin info: /usr/info/octave.info: No such file or directory help: sorry, `sin' is not indexed in the manual

Ok, I actually tested and verified both cases this time ;) Packages addressing this problem are available from: http://people.redhat.com/lhh/octave-2.1.50-3.i386.rpm http://people.redhat.com/lhh/octave-2.1.50-3.src.rpm And will appear in rawhide soon.

octave-2.1.50-3 "help -i sin" works now. but "help sin" still does not work properly: octave:1> help sin sin is a built-in mapper function warning: help: Texinfo formatting filter exited abnormally warning: help: raw Texinfo source of help text follows... -*- texinfo -*- @deftypefn {Mapping Function} {} sin (@var{x}) Compute the sin of each element of @var{x}. @end deftypefn ........

Unfortunately, I couldn't reproduce this on 9, Severn, or Taroon... What version of info are you running?

help -i sin works correctly

I have found what the problem is: octave rpm does not depend on texinfo rpm, but it need texinfo rpm for its online help system. In 'Personal Desktop' installation mode texinfo rpm did not get installed and octave was giving errors while formatting its online system. octave should require texinfo rpm in its dependencies

Ah! Makes sense; I was wondering why I couldn't get it to fail - yet you couldn't get it to work... ;)

That's the correct solution. Building packages.

Added texinfo to "Requires" field. Packages addressing this problem are available from: http://people.redhat.com/lhh/octave-2.1.50-7.i386.rpm http://people.redhat.com/lhh/octave-2.1.50-7.src.rpm These will appear in rawhide soon.

Re-closing due to bugzilla outage earlier today.
