Thanks for your reply.

I have already include that folder in the "Additional library directories", but I have no such .lib files in that directory. 

The compiler need  'gmp-vc90-mt-gd.lib', but what I got here are:

2010/08/09  15:19           497,255 libgmp-10.dll

2010/06/15  19:47           114,286 libgmp-10.lib

2010/08/09  15:19           430,477 libmpfr-4.dll

2010/06/21  15:23            70,696 libmpfr-4.lib

Thanks.

Best,

Yongquan

HI Yongquan,
I had similar issues. I think you need point your linker's "Additional library directories" to the dir where you have your gmp library. This property should be under
"Configuration Properties" -> Linker-> General. For example if CGAL is installed under "Program Files" , you should add C:/Program Files/CGAL 3.7/auxillary/gmp/lib.
This fixed the issue for me.

Thanks for your reply.

Yes, I am pretty sure that I was using the 3.7 version. If the auto-linking is disabled, why the compiler would ask for that file? 

Maybe it is the way that I used to compile the CGAL is not right. 

I am trying to re-compile the CGAL and I do not remember the file existed in that folder. 

Would you please tell me where can I find the information about how to compile the CGAL for Visual Studio 2008?

Thank you very much!

Best,

Yongquan

Are you sure you that you are compiling using the header files of CGAL-3.7?
Since CGAL-3.7, the auto-linking of gmp and mpfr is disabled by default.

What do you have in CGAL-3.7\auxiliary\gmp\lib\ ?
