When I #include <fstream> with mingw64-g++ the PRId64 value is no longer
interpreted correctly.
Here is the test program:
#define __STDC_FORMAT_MACROS
#include <inttypes.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <stdint.h>
#include <fstream>
int main(int argc,char **argv)
{
uint64_t val=1234567890;
printf("%"PRId64"\n",val);
exit(0);
}
[simsong@FC17 ~]$ x86_64-w64-mingw32-g++ -Wall x.cpp
x.cpp: In function 'int main(int, char**)':
x.cpp:19:29: warning: unknown conversion type character 'l' in format [-Wformat]
x.cpp:19:29: warning: too many arguments for format [-Wformat-extra-args]
[simsong@FC17 ~]$
But if I change the test program to this:
#define __STDC_FORMAT_MACROS
#include <inttypes.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <stdint.h>
//#include <fstream>
int main(int argc,char **argv)
{
uint64_t val=1234567890;
printf("%"PRId64"\n",val);
exit(0);
}
Then I have no problem compiling:
[simsong@FC17 ~]$ x86_64-w64-mingw32-g++ -Wall x.cpp
[simsong@FC17 ~]$
[simsong@FC17 ~]$ x86_64-w64-mingw32-g++ --version

This makes no sense to me. Is this a bug?
