Good afternoon,

I have some trouble after installing CGAL on my own machine (windows 7 with
cygwin)

I have followed the steps explained  here
<http://www.cgal.org/Manual/4.1/doc_html/installation_manual/Chapter_installation_manual.html#Section_12>
 
:
cmake . # configure
make # compile
make install # install

Everything went well and there weren't any errors.

Now I am trying to compile and run the sample scripts and run the following
commands:

cgal_create_cmake_script

cmake .

make

Everything goes fine until the make. The hello.cpp exe (see attached) is
created without problems but the hello-exact.cpp fail with the error I
attach at the end of this message. 

  hello.cpp
<http://cgal-discuss.949826.n4.nabble.com/file/n4658326/hello.cpp>  
  hello-exact.cpp
<http://cgal-discuss.949826.n4.nabble.com/file/n4658326/hello-exact.cpp>  

I have been searching the web for quite some time now without finding a
solution. Any ideas?

Thanks!
