[Octave-bug-tracker] [bug #55672] [octave forge] (control) undefined symbol: _Z11warning_msgPKcllPS0_l (development branch)

[Markus Mützel]

Follow-up Comment #6, bug #55672 (project octave):

"long long" is 64-bit on all platforms. Unfortunately, the format specifier
for "long long" is platform specific. d'oh!

In core Octave we solved this in hg id 7f6a50f73625 by defining this macro:

#if defined (OCTAVE_ENABLE_64)
#  define OCTAVE_IDX_TYPE_FORMAT PRId64
#else
#  define OCTAVE_IDX_TYPE_FORMAT PRId32
#endif


Using it is a little wordy, e.g.:

error ("element number %" OCTAVE_IDX_TYPE_FORMAT
       " undefined in return list", k+1);
