how to solve the errors while making the plug-in?

Hi everybody
I've been used the source files of Neohookean PI plugin which is available on your web site. I've made a dll project in visual studio 2010 and added the former files to this project. According to the developer's manual I've added the include and lib path and also I've added the .lib to linker. After a lot of attempts it still fails to build and it gives the following errors. I would be grateful if someone help me to solve these errors.
Code:

Hi Faezeh,

These errors mean that the linker is not able to find some function definitions in the lib files you included. Looking at the functions, it looks like you are missing fecore.lib and febiomech.lib. Did you include these? If you did, the problem can also be that the specified libraries are not compatible with your build. This can happen if you are mixing 32 or 64 bit builds or if you are using libraries built with other versions of Visual Studio. Also, it looks you are building a Debug version so you can try linking to the debug libraries fecored.lib and febiomechd.lib if they are included in your installation. I hope this helps, but keep us posted.

Cheers,

Steve

Hi Steve,
Thanks a lot for your helps. In fact, I have been added the include files and directories and also libraries. the paths which I have been added are as follows:
configuration properties> VC++ directories>include directories> C:\Program Files\febio-2.4.2\sdk\include\
configuration properties> VC++ directories>library directories> C:\Program Files %28x86%29\febio-2.4.2\sdk\lib\VS2010\(which is compatible to the version of my visual studio)
also I have been installed FEbio-win 7-64 bit on my system
I have made some changes in properties but now it gives this error:
1>c:\program files (x86)\febio-2.4.2\sdk\include\febiomech\FESolidMaterial.h(2): fatal error C1083: Cannot open include file: 'FECore/FEMaterial.h': No such file or directory
It's strange. although I have included all directories but it can't find FEMaterial.h
In fact in all include sections I should give the complete path of the include file otherwise it can't find it!!
I don't know what the problem is!
Thanks,
Faezeh

Hi Faezeh,

You state the include directory is:

C:\Program Files\febio-2.4.2\sdk\include\

But the error says the compiler is looking for a file in: C:\Program files (x86)\febio-2.4.2\skd\include\ (Notice the x86 in Program Files).

Could that be the issue?

Cheers,

Steve

Hi Steve,
No, The path is true. I made a mistake in writing the address here!
