[Octave-bug-tracker] [bug #63462] sscanf reports incorrect number of output values.

[Dmitri A. Sergatskov]

Follow-up Comment #12, bug #63462 (project octave):

I think his configure says "Ubuntu 20.04".

ldd output on fedora is equally longish:

ldd picking up some installed libraries should not be a problem per jwe
(https://octave.discourse.group/t/bump-soname-number-for-liboctinterp-so-and-liboctave-so/3639):


I don’t think there is a problem with the library version when running
Octave in the build directory if you use the run-octave script. It uses
libtool to execute Octave and should be correctly setting up the necessary
environment to use the library files in the build directory tree.


But perhaps OP runs ./src/.libs/octave-cli directly?

Dmitri.
