[Octave-bug-tracker] [bug #45346] octave crashes when trying to install database package

[Olaf Till]

Follow-up Comment #9, bug #45346 (project octave):

Wandering why your 2nd backtrace also shows no debugging information for
liboctinterp.so.2 I realized that it's the wrong library. Sorry, had I seen
this before it probably would have spared you the work ... While your Octave
is loaded from a local installation:

Starting program: /usr/local/bin/octave --no-gui-libs

The used liboctinterp is from a system directory:

#8  0x00007fffdef9056b in ?? () from
/usr/lib/x86_64-linux-gnu/liboctinterp.so.2

, probably a leftover of a previous Octave installation from a Debian package.
This does not only hinder debugging, it may be even the cause of the observed
crash (although I wander how it happens that Octave can load the wrong
library).

What you can do to test your new Octave without the interfering old library:

If you don't need the Octave from the Deb package, deinstall the Deb package
and check that /usr/lib/x86_64-linux-gnu/liboctinterp.so.2 is indeed not
present anymore. It may be possible then to use your compiled Octave without
recompilation.

If you still need the old Octave, try (without recompilation)

export LD_LIBRARY_PATH="/usr/local/lib"

/usr/local/bin/octave


If this does not help, you could

export LD_RUN_PATH="/usr/local/lib"

(and possibly also: export LD_LIBRARY_PATH="/usr/local/lib")

before

make clean; ./configure; make

of your new Octave.
