Question

Well, actually this is easy to do in Visual Studio 2010. I include windows.h, and done. But i’m trying to do this in Qt, however no success. I included windows.h but still GetPhysicallyInstalledSystemMemory() isn’t defined.

Answer 1

GetPhysicallyInstalledSystemMemory function isn’t included in current MinGw windows.h header. But you can declare it yourself:

extern "C"
WINBASEAPI BOOL WINAPI GetPhysicallyInstalledSystemMemory (PULONGLONG );

Then, liking with kernel32 allows you to use it:

g++ source.cpp -lkrenel32
