Hi Tina,

How did you compile poisson_reconstruction_example?
The recommended way is to run CMake that will find third party libraries like GMP and generate a VC++ project. Then you can compile as usually with VC++. See "Configuring and Building Programs Using Cgal" http://www.cgal.org/Manual/last/doc_html/installation_manual/Chapter_installation_manual.html#Section_7

Regards,
Laurent Saboret

Thanks Laurent, how should I do that? I guess that should be problem but when I checked my c++ directory , it was already in lib and include file,  it is also in the windows environment "path" too. is there somewhere else that I need to check.

Thanks,
Tina

Looks like you need to link with GMP library.

I get following linker error:
