CGAL users discussion list

[Karen Daniels <>]

I am also unable to build the examples and demos, so something is going wrong early on as well.  I have installed earlier versions of CGAL numerous times on other platforms and never had this amount of trouble.

Here is what cmake is complaining about with regards to examples and demos.  It appears to be adding duplicative prefixes to directory paths and I don't know why:

CMake Error at C:/Program Files (x86)/CMake 2.8/share/cmake-2.8/Modules/Qt4Macros.cmake:64 (FILE): file problem creating directory: C:/Program Files (x86)/CGAL-4.0.2/demo/C:/Program Files (x86)/CGAL-4.0.2/demo/Alpha_shapes_2 Call Stack (most recent call first): C:/Program Files (x86)/CMake 2.8/share/cmake-2.8/Modules/Qt4Macros.cmake:202 (QT4_MAKE_OUTPUT_FILE) demo/Alpha_shapes_2/CMakeLists.txt:40 (qt4_add_resources)

I did use the installer.  When running cmake it looks like the gmp and mpfr libraries are the ones I downloaded.
I wonder if the problem is that I'm trying to put together a debug version and perhaps the gmp libraries bundled with CGAL 4.0.2  are only for the release version??

When running cmake, is the library found for gmp and mpfr the one
you downloaded?

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:

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