Configure only checks whether LONG_LONG_MAX or LLONG_MAX (Solaris &
BSD) are defined in limits.h,
Yes, actually in limits.h, there's no LONG_LONG_MAX defined. And
configure gives the following otuput in base:
checking whether precompiler handles LONG_LONG_MAX... no
It should also check for LLONG_MAX in that case.
checking whether we have LLONG_MAX... no
Alternatively you could try to find a work-around in your tool to
not use -scanLongLong: (probably easier, if that's an option)
I don't remember using it. Could it be, that it's invoked by another
method, e. g. -scanInt or -scanLong?
Quite possibly, depending on the libraries/frameworks you're including.
I did a quick scan on the exception notice and on scanLongLong. Both
appear only once in -core, in NSScanner.m
I actually found it in my code and might be able to temporarely replace
it with a -scanLong. But that's not really the solution that pleases.
so you may have to check whether SuSE uses one
of these or uses a different definition.
[...]
If the latter, this would have to be added to the checks.
It doesn't seem, that there's a suitable one, is it?
Well, on my box here (FreeBSD) LLONG_MAX is actually defined in
/usr/include/machine/limits.h which is included from limits.h
So you may have to "dig deeper". You could/should try a recursive grep
on your system's /usr/include.
I did that and found out, that I actually looked at
'/usr/include/linux/limits.h'. But there's another in '/usr/include'.
And this one seems promising. I quoted it at the end of this posting.
It seems to me, that the definition is somehow excluded by some ifdefs.
But please have a look yourself.
