[SOLVED]Linking problems: Qt5.5 32bit VS2013

JasonKretzer

I have been searching for an answer to this but no luck as yet.

Using Qt5.5 32bit, VS2013 on Win8 64bit

My .pro file contains this:

INCLUDEPATH += "C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Include"
LIBS += -L"C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib" -ladvapi32

I have checked both folders and WinUser.h is in the Include and User32.lib is present in the Lib.

I have the following two functions in my code:

void suppressAnimations()
{
    ANIMATIONINFO m_original_settings;
    m_original_settings.cbSize = sizeof(m_original_settings);
    if (::SystemParametersInfo(SPI_GETANIMATION, sizeof(m_original_settings), &m_original_settings, 0)) {
        ANIMATIONINFO no_animation = { sizeof(no_animation), 0 };
        ::SystemParametersInfo(SPI_SETANIMATION, sizeof(no_animation), &no_animation, SPIF_UPDATEINIFILE | SPIF_SENDCHANGE);
    }
}

AND

int BackgroundTaskManager::changeMonitorState(bool turnOn)
{
    int lparam = 2;
    if(turnOn) {
        lparam = -1;
        BackgroundTaskManager::MonitorIsSleeping = false;
    } else {
        lparam = 2;
        BackgroundTaskManager::MonitorIsSleeping = true;
    }
    return SendMessage(HWND_BROADCAST, WM_SYSCOMMAND, SC_MONITORPOWER, (LPARAM)lparam);
}

I use this exact same code with Qt 5.3.2 32bit VS2010 on Windows 7 64bit and it compiles with no problems. In my current configuration, I get linking errors on the ::SystemParametersInfo and the SendMessage parts of the functions and a bunch of warnings on the headers.

Warnings

C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Include\sal_supp.h:57: warning: C4005: '__useHeader' : macro redefinition

Linking Errors

main.obj:-1: error: LNK2019: unresolved external symbol __imp__SystemParametersInfoW@16 referenced in function "void __cdecl suppressAnimations(void)" (?suppressAnimations@@YAXXZ)
backgroundtaskmanager.obj:-1: error: LNK2019: unresolved external symbol __imp__SendMessageW@16 referenced in function "private: int __thiscall BackgroundTaskManager::changeMonitorState(bool)" (?changeMonitorState@BackgroundTaskManager@@AAEH_N@Z)

Another bit of information, I tried this also using Qt5.5 32bit VS2013 on Win7 64bit and also received the errors as above. Yet another bit of information, in Qt Creator, I can press F2 over either of the symbols above and it takes me to the correct header.

Could someone point me in the correct direction?

Well, the lib might be in the directory, but you didn't add it to the linker.

LIBS += -L"C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib" -ladvapi32 -luser32

@Leonardo Thanks!
