Actually the question is:

  1. What libraries need to be downloaded.
  2. Where they can be downloaded.
  3. How to connect them.
  4. And is it possible to use the old code, such as a calculator, in a future program.

    On Delphi under Simba program will not work. The compiler does not know how to build platforms other than x86 for platforms.

    • Delphi XE2 already knows how under x64 and OS X) - Nofate ♦

    Under Symbian, you can program on qt, you can take it here: qt.nokia.com, there you can download the IDE Qt creator, it has all the necessary libraries, but you will most likely have to use C ++, can I use Delphi? sure

      The compiler can build platforms other than x86, but unfortunately there is no Symbian.
