[Octave-bug-tracker] [bug #50510] 64-bit build issue

[John W. Eaton]

Follow-up Comment #2, bug #50510 (project octave):

suitesparse provides interfaces for both 32- and 64-bit integers.  With
whatever package system we are using on OS X, it is configured to use "long
int" for 64-bit integers.  That is not identical to int64_t, which is a
typedef for "long long int" on that system.

We don't get to choose what typedef is used for suitesparse if we are using
someone else's packaged version of it.

Yes, other systems could have similar issues.  We build everything ourselves
on Windows and we use typedefs that match.

We could see the same for Linux systems if "long int" and "long long int" were
mixed.  They are the same size.  But we appear to be lucky there and everyone
seems to use "long int" and that's the same as what is used for "int64_t".
