3.2.2 Which components do I need to compile Pascal code?

A complete Pascal compiler system should at least have:

1. The actual compiler, GPC.
2. An editor, assembler, linker, librarian and friends.
3. A C library. If you have a working C compiler, you already have this.
4. A debugger, if you want to debug your programs.

For most people, the GNU binutils and GNU debugger (gdb) are a good choice, although some may prefer to use vendor specific tools.
