I wrote a very simple test code of printf uint64_t:
#include <inttypes.h>
#include <stdio.h>
int main()
{
uint64_t ui64 = 90;
printf("test uint64_t : %" PRIu64 "\n", ui64);
return 0;
}
I use ubuntu 11.10 (64 bit) and gcc version 4.6.1 to compile it, but failed:
main.cpp: In function ‘int main()’:
main.cpp:9:30: error: expected ‘)’ before ‘PRIu64’
main.cpp:9:47: warning: spurious trailing ‘%’ in format [-Wformat]
Since you've included the C++ tag, you could use the {fmt} library and avoid the PRIu64
macro and other printf
issues altogether:
#include <fmt/core.h>
int main() {
uint64_t ui64 = 90;
fmt::print("test uint64_t : {}\n", ui64);
}
The formatting facility based on this library is proposed for standardization in C++20: P0645.
Disclaimer: I'm the author of {fmt}.
When compiling memcached under Centos 5.x i got the same problem.
The solution is to upgrade gcc and g++ to version 4.4 at least.
Make sure your CC/CXX is set (exported) to right binaries before compiling.
