Linking to windows libs failure

[yi gi]

Hi All,
In my project I am trying to link to the libs Imm32.lib, Winmm.lib, ws2_32.lib and User32.lib but I can't seem to make it work.
any idea what I'm doing wrong?

.PRO:

What doesn't work about it?

You seem to trying to build a generic Win32 application with no Qt components. If that is the case you may as well use the Visual Studio tools directly.

I have a generic Win32 application that I'm trying to embed (with tweaks) into a QT application.
Specifically I need to incorporate the Cypress USB Library CyAPI library but get linkage errors such as:

camera.obj:-1: error: LNK2019: unresolved external symbol "public: bool __thiscall CCyUSBEndPoint::XferData(unsigned char *,long &,class CCyIsoPktInfo *)" (?XferData@CCyUSBEndPoint@@QAE_NPAEAAJPAVCCyIsoPktInfo@@@Z) referenced in function "public: bool __thiscall Camera::SendDataToRegister(int,int)" (?SendDataToRegister@Camera@@QAE_NHH@Z)

camera.obj:-1: error: LNK2019: unresolved external symbol "public: bool __thiscall CCyUSBEndPoint::XferData(unsigned char *,long &,class CCyIsoPktInfo *)" (?XferData@CCyUSBEndPoint@@QAE_NPAEAAJPAVCCyIsoPktInfo@@@Z) referenced in function "public: bool __thiscall Camera::SendDataToRegister(int,int)" (?SendDataToRegister@Camera@@QAE_NHH@Z)

To copy to clipboard, switch view to plain text mode 

From what I was able to gather I need those Win32 libraries to solve these errors, hence my current predicament.

You are directing the linker to the 64-bit "../lib/x64/" version of the USB library and 32-bit versions of Windows API and OpenCV. These need to match the bit-ness of your program.

Do yourself a favour and change all the "\\" in PRO file paths to "/" and improve the reability.
I would also consider commenting out the Windows SDK stuff until you are certain they are needed.
