gnatls ¶You run the gnatls command as follows:
$ gnatls switches object_or_ali_file
The main argument is the list of object or ali files
(see The Ada Library Information Files)
for which you are requesting information.
In the default mode, without additional options, gnatls produces a
four-column listing. Each line contains information for a specific
object. The first column gives the full path of the object, the second
column gives the name of the principal unit in the object, the third
column gives the status of the source and the fourth column gives the
full path of the source representing this unit.
Here’s a simple example:
$ gnatls *.o ./demo1.o demo1 DIF demo1.adb ./demo2.o demo2 OK demo2.adb ./hello.o h1 OK hello.adb ./instr-child.o instr.child MOK instr-child.adb ./instr.o instr OK instr.adb ./tef.o tef DIF tef.adb ./text_io_example.o text_io_example OK text_io_example.adb ./tgef.o tgef DIF tgef.adb
You should interpret the first line as follows: the main unit, which is
contained in
object file demo1.o, is demo1, whose main source is in
demo1.adb. Furthermore, the version of the source used for the
compilation of demo1 has been modified (DIF). Each source file has a status
qualifier which can be:
The version of the source file used for the compilation of the specified unit corresponds exactly to the actual source file.
The version of the source file used for the compilation of the
specified unit differs from the actual source file but not enough to
require recompilation (e.g., only comments have been changed). If
you run gnatmake with the option -m (minimal
recompilation), it will not recompile a file marked MOK.
No version of the source found on the path corresponds to the source used to build this object.
No source file was found for this unit.
The version of the source that corresponds exactly to the source used for compilation has been found on the path but it is hidden by another version of the same source that has been modified.
