This is going to be a big “Doh!” when I see the answer…
In testatomic.c I need to printf the value of Uint64 variable. Ok, no
problem, %llu should just work. And, in fact it does work. The value
comes out just fine.
BUT! I get the following warning everywhere I do that.
testatomic.c:85: warning: format ?%llu? expects type ?long long
unsigned int?, but argument 3 has type ?Uint64?
testatomic.c:88: warning: format ?%llu? expects type ?long long
unsigned int?, but argument 2 has type ?Uint64?
testatomic.c:91: warning: format ?%llu? expects type ?long long
unsigned int?, but argument 2 has type ?Uint64?
I’m using gcc --version == gcc (Ubuntu 4.3.3-5ubuntu4) 4.3.3
I’m on an AMD x86_64 machine with and cat /proc/version == Linux
version 2.6.28-15-generic (buildd at yellow) (gcc version 4.3.3 (Ubuntu
4.3.3-5ubuntu4) ) #49-Ubuntu SMP Tue Aug 18 19:25:34 UTC 2009
I’m using the latest SDL 1.3 from svn.
I have also tried Lu and I get the same result.
I just hate having code generate such a long list of warnings.
And, yeah, since Uint64 is an SDL datatype this is an SDL related
problem. And, yeah, I have googled it and RTFMed and what I have
works, it just gives a nasty warning message and that is what I want
to get rid of.

It’s a pointless warning in this case. ‘long long unsigned int’ is
equivalent to ‘Uint64’ in terms of its storage capacity.
I suspect the rationale behind the warning is that someone might
typedef ‘sometype_t’ and then later change the size of it to be uint32
instead of uint64 or something, while leaving the printf()s to use
"%llu". It’s a “be careful what you’re doing here, you might screw it
up” warning.
I’m not sure what the proper way to silence the warning is, but the
compiler flag -Wno-format should shut it up.

You could always cast the parameter to: (long long unsigned int). That
should shut up the compiler.> ----- Original Message -----

I’m pretty sure ‘inttypes.h’ isn’t included with MSVC, so that’d screw
with cross-platform compatibility. But then again, I don’t think
"%llu" is supported by MSVC either (isn’t it “%I64” or something
idiotic like that?)

Yep, that did it! I knew it would be “Doh!” moment when I saw the answer.
Anyway, I just checked it in.

Great, now everyone using MSVC is going to get error messages. Anyone
want to fix it for VC?
