Did you read (and foillow) the GNAT rules for filenames given in the
Gnat User's Guide, viz.:

File Naming Rules
The default file name is determined by the name of the unit that the
file contains. The name is formed by taking the full expanded name of
the unit and replacing the separating dots with hyphens and using
lowercase for all letters.

An exception arises if the file name generated by the above rules
starts with one of the characters a,g,i, or s, and the second
character is a minus. In this case, the character tilde is used
in place of the minus. The reason for this special rule is to
avoid clashes with the standard names for child units of the
packages System, Ada, Interfaces, and GNAT, which use the prefixes
s- a- i- and g- respectively.

The file extension is `.ads' for a spec and `.adb' for a body. The
following list shows some examples of these rules.

`main.ads'
Main (spec)
`main.adb'
Main (body)
`arith_functions.ads'
Arith_Functions (package spec)
`arith_functions.adb'
Arith_Functions (package body)
`func-spec.ads'
Func.Spec (child package spec)
`func-spec.adb'
Func.Spec (child package body)
`main-sub.adb'
Sub (subunit of Main)
`a~bad.adb'
A.Bad (child package body)

Also, you specified neither the compiler version nor the platform
on which you're working.
