Hi Andreas,

Thank you very much, your suggestions works like a charm. I am able to build the examples using the existing CmakeLists.txt

My next question will be how do I visualize the generated output. For example, I am trying the example "Surface_reconstruction_points_3" and poisson_reconstruction. I tried with the sample data file provided "data/kitten.xyz" and can export the output file in .xyz format. Once I am done, how do I visualize the original file "data/kitten.xyz" and surface constructed file which is "output.xyz" for my case.

This may be known to others but as a new starter, I am wondering if you can point me towards some visualizer that I can look at.

Thanks again for the help,

Chiranjib Sur

Hi Andreas,
Thank you very much for the message. Just to know more here are the
things I am doing :

1. Trying to compile the example Surface_modeling (cgal 4.5)
2. Steps i followed :
a) create the CMakeLists.txt by using the script "cgal_create_CMakeLIsts

Isn't there already a CMakeLists.txt ??
You overwrite it when you run the script
And in the one overwritten was a  find (Eigen)

andreas

b) run cmake to generate make file
c) run make to compile

Things are ok upto generating makefile but when I run make, I get the
compilation error.

As you suggested, what do you mean "when you configure cmake" ? Do you
mind sending few more information about the steps one needs to follow to
compile this example ?

Thanks again,
CHiranjib

    When you configure an example using cmake you have to give it

        Hi,
        I am very new to CGAL and I am learning/using this for the first
        time. I
        faced similar problems and found this thread. However, I have a
        questions:

        What do you mean by adding "#define CGAL_EIGEN3_ENABLED worked
        fine".

        Where you add this line too ?

        There are many examples which gives similar compilation error.
        Is there any
        global setting that I can modify so that the compilation goes
        smoothly?

        Thanks in advance.
