hi Tina,

actually - I am having the same problem with GMP and visual.

choose the option: MFC in a shared lib and MT DLL code generation - not static.

Hi Laurent,

Thank you for your reply. I tried with the cmake too but still same errors. I even addressed all the lib files in my code individually and still have same error. I am guessing the problem is not finding library. maybe I am missing some of  the lib file.  I have following files :

"C:\CGAL\CGAL-3.5\auxiliary\gmp\lib" :
gmp-vc90-mt.lib
gmp-vc90-mt-gd.lib
gmp-vc90-mt-s.lib
gmp-vc90-mt-sgd.lib
mpfr-vc90-mt.lib
mpfr-vc90-mt-gd.lib
mpfr-vc90-mt-s.lib
mpfr-vc90-mt-sgd.lib

gmp-vc90-mt.dll
gmp-vc90-mt-gd.dll
mpfr-vc90-mt.dll
mpfr-vc90-mt-gd.dll

and in "C:\CGAL\CGAL-3.5\auxiliary\gmp\include" :
gmp.h
mpfr.h

Is there any file missing? I really appreciate your help, I don't know what else should I do.

Thank you,
Tina

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

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.
