    CGAL in Linux

    Hello from ubuntu 12.04.

    I want to use CGAL and I installed it. The examples run just fine. The graphical applications seem to have a problem (the require Qt I guess), but that's ok for now.

    I can build the examples like this
    Code:
    cmake -DCGAL_DIR=$HOME/CGAL-3.6.1 . 
    make
    Then I run them with the typical way.

    However, I am not able to build a new example.
    I create a new .cpp and I copy the exact same code from another example (that was built and run ok).

    I tried to modified the Makefile that was already there, but no result.

    Any idea? :/ I am stuck for good!

    It’s 2014 and I still use printf() for debugging.

    Are you also making these new files in the same directory as your working examples?

    Yes. But these examples were already there, as their makefile.

    If I understood correctly, I should somehow invoke cmake in the play!

    What are the errors you're getting specifically? Like, what's the compiler or cmake or w/e spitting out at you? Or is it just a silent failure?

    It ignores my new file. When I try something like compilation by hand, the screen can't hold the errors :P
    I guess, I just have to read carefully again their info in their site.

    Now, I tried with cgal_create_cmake_script (instead of cgal_create_CMakeLists) and it is ok. The script name depends on which version of Cgal you use.
    Cgal users tell me to install a newer version of Cgal.
    I had found this, which is where the also told me to look. I am on ubuntu 12.04. However, I know only how to handle the terminal for coding purposes (not installing, etc.) and I do not know what to do.

    What are the errors? Are they happening with cmake or make? If there are too many to post, redirect stderr and put them on pastebin or something... E.g.:

    make 2> mkerrs.txt

    Yesterday, the 4.3 version was released and I installed it successfully.
    If someone wants to know how, he can find the instructions I followed in pseusosite.

    I think command on ubuntu was actualy

    sudo apt-get install libcgal-dev

    Using native package managers is always better when not using source based distros, at least imo.
