Discriminating Ada source code through compiler arguments

Discriminating Ada source code through compiler arguments

[ada_develop]

Hello. I´m a newie in Ada and I want to known how can I pass arguments
to the compiler to discriminate parts of a Ada source code. Something
like the #ifdefs that we can use in the C programming languaje.

Thank you.

This really depends on your compiler. There is not standard for doing
this in Ada. Note that this is by design, #ifdef is considered bad
practice and a maintenance nightmare!

If you are using GNAT you can check gnatprep.

But a better solution is often to have one spec and multiple bodies for
different implementations. But without knowing more about your goal it
is difficult to devise the solution.
