Error with gcc 4.7.1

Error with gcc 4.7.1

[Pranith Kumar]

Hi,

I am getting the following error when using gcc 4.7.1 to compile:

snprintf(temp, sizeof(temp)/sizeof(temp[0]), "%"PRIi64, value);

error: unable to find string literal operator ‘operator"" PRIi64’

This compiles fine with Intel compiler. Is this a bug? Is there any 
workaround?

Thanks,
Pranith

add a space between "%" and PRIi64 -> '"%" PRIi64'

Your error has to do (as far as I can see) with the new user defined 
literals in c++11.  To the compiler, "%"PRIi64 looks like a user-defined 
literal.  I'm assuming that PRIi64 is a #define to some literal string.

If you add a space between the two, you should be fine.

Yes, as required by C99 and later standards.

Well, required if int64_t is provided anyway.

It's not a bug.  See the "User-defined literals and whitespace"
section of http://gcc.gnu.org/gcc-4.7/porting_to.html
