Hello,
I'm trying to use std::strtoull in a C++ program, but compiling it I get:
error: 'strtoull' is not a member of 'std'
It works, if I use strtoul ('unsigned long' versus 'unsigned long long'
above).
Cygwin uses newlib and I checked the documentation on the newlib homepage:
It provides both the 'unsigned long' and the 'unsigned long long' version.
Also cygwin/gcc allows to use 'unsigned long long' variables. So it's not
that everything related 64 bit is not available, because I'm compiling for
a 32bit Windows. Is there a special option I should use to get access to
more 64 bit methods?
Here is a simple test program to show the effect:
#include <cstdlib>
int main(int argc, char** argv)
{
unsigned long long l = 0;
l = std::strtoull("0x100", NULL, 16);
return 0;
}
This is the call to the compiler:
$ g++ -Wall -o tt tt.cpp
tt.cpp: In function 'int main(int, char**)':
tt.cpp:7:9: error: 'strtoull' is not a member of 'std'
Here is my version of cygwin and gcc / g++:
CYGWIN_NT-5.1 XXXXXXXX 1.7.9(0.237/5/3) 2011-03-29 10:10 i686 Cygwin
g++ (GCC) 4.5.3
