    <p>Hello Pedro,</p>
    <p>that is more a matter of your compiler and your system than of
      GiNaC.<br clear="none">
      Since you are on ubunte and ginac.h is already in
      /usr/include/..., the program can be compiled with <br clear="none">
    </p>
    <p>   <tt>    g++ program.cpp -lginac</tt></p>
    <p>(-lginac tells the linker to load the library).</p>
    <p>However, your program has an error, since poly is not defined.
      Add</p>
    <p><tt>ex poly;</tt></p>
    <p>above your for-loop, then it runs fine.</p>
    <p>Kind regards,</p>
