'GetTickCount64' was not declared in this scope

[DarthCaniac]

Hello,

I have been researching this without stop for about 8 hours now and am at my wits end!
I have the following code:

#define WINVER 0x0601
#define _WIN32_WINNT 0x0601

#include <iostream>
#include <windows.h>

using namespace std;

int main()
{
  ULONGLONG tickCount64 = GetTickCount64();
  cout << tickCount64;
}

I am compiling with this:
g++ file.cpp -o program.exe

Each time, it tells me:

file.cpp:13:42: error: 'GetTickCount64' was not declared in this scope
   ULONGLONG tickCount64 = GetTickCount64();
                                          ^

If I change it to GetTickCount (Without the 64), it works great. I am not running XP or anything like that, and I made sure to define the winver as Vista.
I've tried including libraries by hand, trying to add "Win32::" (And other similar combinations) in front of the function and more.

Any assistance would be most appreciated!

Thanks for the reply!
Unfortunately not. I've read that page through end to end a few times with no luck.

The code should build okay, that means that you development environment needs updating.

Isn't Vista 0x0600?

You need
#define _WIN32_WINNT 0x0600 before including windows.j

@Canis

Whoops, you're right! 0601 is Windows 7.

Makes no difference :(

Sorry, I skipped your first post. But my solution shoulld have worked too since GetTickcount64() is defined as follows:

#if (_WIN32_WINNT >= 0x0600) 
//...
WINBASEAPI ULONGLONG WINAPI GetTickCount64(void);

#endif 

maybe something has been hanged between different gcc versions

Your original code compiles fine using MinGW-w64 runtime from http://tdragon.net/recentgcc/ .

-------------- Build: Release in PrintEnv (compiler: GNU GCC Compiler)---------------

g++.exe -Wall -fexceptions -m32 -D_WIN32 -O2 -c "D:\PROGRAMARE\PROIECTELE MELE\PrintEnv\main.cpp" -o obj\Release\main.o
g++.exe -L"..\..\..\CURL MinGW\lib" -o bin\Release\PrintEnv.exe obj\Release\main.o -m32 -s
Output file is bin\Release\PrintEnv.exe with size 536.00 KB
Process terminated with status 0 (0 minute(s), 2 second(s))
0 error(s), 0 warning(s) (0 minute(s), 2 second(s))

If your compiler does not support GetTickCount64 then use GetProcAddress() API to load the function at runtime from kernel32.dll.

You are a life saver! Thank you Modoran!

I downloaded that version of GCC and now the code compiles as nicely as can be. Thank you all very much for your help!
