CGAL users discussion list

[Karen Daniels <>]

I'm looking for help with CGAL 4.0.2 and GMP using 64-bit Windows 7 and 
Visual Studio 2010 .   I downloaded the precompiled GMP files as 
instructed and I built the 64-bit Debug version of CGAL 4.0.2 using 
cmake-gui.

I added the CGAL and GMP lib directories locations to my Visual Studio 
project's (Debug mode) property page under VC++ Directories -> Library 
Directories.  I also explicitly added libgmp-10.lib and libmpfr-4.lib as 
additional dependencies under Linker -> Input.

In spite of that, I have unresolved symbols for example program:

1>Example.obj : error LNK2019: unresolved external symbol 
__imp____gmpq_clear referenced in function "public: __thiscall 
CGAL::Gmpq_rep::~Gmpq_rep(void)" (??1Gmpq_rep@CGAL@@QAE@XZ)

I have previously built other versions of CGAL using Visual Studio, but 
not under Windows 7.
Any help would be greatly appreciated.
