[Octave-bug-tracker] [bug #30478] prelinking causes octave to crash

[John W. Eaton]

Follow-up Comment #24, bug #30478 (project octave):

Now I'm getting a bit confused.  Is this bug report about prelinking or
what?

You say that Octave runs and passes make check, but crashes on startup if you
install it?  I have no clue why that would happen.

What happens if you run gdb on your core file and type

  where

at the (gdb) prompt?  Does that give any useful information about where in
Octave the crash is happening?  If you can't say where in Octave the crash is
happening, then I think I'll have to give up trying to debug this problem.

I would not expect that you should have to copy exactly the compiler flags
used to compile your BLAS library, provided that pointers and ints have the
correct sizes.  Unless you are compiling Octave with --enable-64, pointers on
a 64-bit system are assumed to be 8 bytes but integers are 4 bytes.  I think
that is what -m64 does, so it should be OK.  And I think that is also the
default for a 64-bit system, so should not really be necessary.  But anyway,
if Octave does run make check successfully, I don't see how this could be the
problem.
