Compiling Errors on GetProcessMemoryInfo function
May 16, 2010 at 11:56 am 3 comments
I recently used GetProcessMemoryInfo function to measure memory usage of working processes on Windows. I firstly tried with the example code “Collecting Memory Usage Information For a Process” in MSDN but the compiling produced some external linking errors on my Windows XP box:
Error 1 error LNK2019: unresolved external symbol _GetProcessMemoryInfo@12 referenced in function “void __cdecl PrintMemoryInfo(unsigned long)” (?PrintMemoryInfo@@YAXK@Z)
Error 2 error LNK2019: unresolved external symbol _EnumProcesses@12 referenced in function _main
Error 3 fatal error LNK1120: 2 unresolved externals
To fix this issue, I added “pragma comment” instruction to places a library-search record in the object file and compiling is now working fine.
#include <windows.h>
#include <stdio.h>
#include <psapi.h>
#pragma comment(lib, “psapi.lib”) //added

if Above Pragma don’t work then use
#pragma comment(linker, “/DEFAULTLIB:psapi.lib”)

That solved my problem – it would have taken about a week otherwise 😉 thanks very much.
