compiling qperft by H.G.Muller mistake

[Uri Blass]

I tried to compile qperft by H.G.Muller with Visual C++2008 and I get the error
unresolved external symbol _lltoa

I wonder how do I fix this error and what does the folowing code does.


lltoa(count-ocnt, buf, 10);

lltoa(count, buf, 10);

lltoa(count, buf, 10);

Seems to be a typo. Try itoa.

Try to replace with

Code: Select all

sprintf(buf,"%lld",count);

Edit: lowercase letter "L"

replace all instances >

lltoa with ltoa

Neither itoa nor ltoa should be used, but rather the %llu format in printf. itoa and ltoa take a long int, which in 32-bit environments should only be 32 bits. %llu takes a long long. It's also easier to use the %llu since there's already a printf there.

EDIT: I changed it to %llu instead of %lld, in case a perft value gets over 9 quintillion

On the compiler I was using at the time, (gcc/Cygwin) %lld did not work. lltoa (= long long int to ascii) was the only way I could find to print a long long int.

Microsoft calls their 64 bit type __int64, so the function is called _i64toa.
