1>LINK : fatal error LNK1104: cannot open file

Question

I am trying to add external libraries to my project but I always get this error LINK : fatal error LNK1104: cannot open file 'C:\Users\Lubdmila\Desktop\OpenMAT-1.3.4\lib\x86.obj'. I was following these instructions: (I was given these instructions ) The LpSensor library contains classes that allow a user to integrate LPMS devices into their own applications. The standard library is a Windows 32-bit C++ library for MS Visual C++ (express) 2010. Should you require a binary of the library to work on another operating system or 64-bit applications, please contact LP-RESEARCH.

Compiling applications that use the LpSensor library requires the following components:

Header files (usually in C:/OpenMAT/include):

LpmsSensorManagerI.h Contains the interface for the LpmsSensorManager class.

LpmsSensorI.h Contains the interface for the LpmsSensor class

ImuData.h Structure for containing output data from a LPMS device

LpmsDefinitions.h Macro definitions for accessing LPMS

DeviceListItem.h Contains the class definition for an element of a LPMS device list

LIB files (usually in C:/OpenMAT/lib/x86):

LpSensorD.lib LpSensor library (Debug version)

LpSensor.lib LpSensor library (Release version)

DLL files (usually in C:/OpenMAT/lib/x86): LpSensorD.dll LpSensor library (Debug version)

LpSensor.dll LpSensor library (Release version)

PCANBasic.dll PeakCAN library DLL for CAN interface communication (optional).

ftd2xx.dll The FTDI library to communicate with an LPMS over USB.

To compile the application please do the following:

1. Include LpmsSensorManagerI.h.

2. Add LpSensor.lib (or LpSensorD.lib if you are compiling in debug mode) to the link libraries file list of your application

3. Make sure that you set a path to LpSensor.dll / LpSensorD.dll, PCANBasic.dll (optional) and ftd2xx.dll so that the runtime file of your application can access them.

4. Build your application.

I am using MS Visual Studio 2010 express 32-bit.And this is what I have done:

1) Project/Properties/Configuration Properties/C/C++/General/Additional Include Directories path---C:\Users\Lubdmila\Desktop\OpenMAT-1.3.4\include

2)Project/Properties/Configuration Properties/Linker/General/Additional Library Directories---C:\Users\Lubdmila\Desktop\OpenMAT-1.3.4\lib\x86

3)Project/Properties/Configuration Properties/Linker/Input/Additional Dependencies---C:\Users\Lubdmila\Desktop\OpenMAT-1.3.4\lib\x86

4) Project/Properties/Configuration Properties/VC++ Directories/General/ Include Directories path---C:\Users\Lubdmila\Desktop\OpenMAT-1.3.4\include

5) include "LpmsSensorManagerI.h"

I have tried to add quotes around the paths but it did not help.I have no clue why I am getting this error.

Does anyone know what I am doing wrong? Thank you

Answer 1

It seems you have mistakenly added " C:\Users\Lubdmila\Desktop\OpenMAT-1.3.4\lib\x86 " to the additional dependencies under

" Properties/Linker/Input/Additional Dependencies- "

In this section you should simply list your additional library names, such as

" LpSensor.lib "

The path " C:\Users\Lubdmila\Desktop\OpenMAT-1.3.4\lib\x86 " is already set in " Properties/Linker/General/Additional Library Directories--- " for the linker to look for.

Answer 2

It works now. I created a new project did the same steps but I changed step 3 as harry 268 advised and then I added path to dll files. Here's the link to the solution: How to add a path to dll files

Visual Studio: how to set path to dll?

Answer 3

In my case I had fatal error LNK1104: cannot open file 'C:\Users\..\proj.exe'

in order to solve this issue, I just copied whole proj folder and renamed it. and that is working now
