The usual form of the
gnatmake command is
$ gnatmake [switches] file_name [file_names] [mode_switches]
The only required argument is one file_name, which specifies
a compilation unit that is a main program. Several file_names can be
specified: this will result in several executables being built.
switches are present, they can be placed before the first
file_name, between file_names or after the last file_name.
If mode_switches are present, they must always be placed after
the last file_name and all
If you are using standard file extensions (.adb and .ads), then the
extension may be omitted from the file_name arguments. However, if
you are using non-standard extensions, then it is required that the
extension be given. A relative or absolute directory path can be
specified in a file_name, in which case, the input source file will
be searched for in the specified directory only. Otherwise, the input
source file will first be searched in the directory where
gnatmake was invoked and if it is not found, it will be search on
the source path of the compiler as described in
3.3 Search Paths and the Run-Time Library (RTL).
When several file_names are specified, if an executable needs to be rebuilt and relinked, all subsequent executables will be rebuilt and relinked, even if this would not be absolutely necessary.
gnatmake output (except when you specify
^-M^/DEPENDENCIES_LIST^) is to
`stderr'. The output produced by the
^-M^/DEPENDENCIES_LIST^ switch is send to
