14. Rebuilding the GNAT Library

It may be useful to recompile the GNAT library in various contexts, the most important one being the use of partition wide configuration pragmas such as Normalize_Scalar. A special Makefile called Makefile.adalib is provided to that effect and can be found in the directory containing the GNAT library. The location of this directory depends on how the GNAT environment has been installed and can be located with the command

$ gnatls -v

The last line of the Object Search Path usually contains the gnat library. This Makefile contains its own documentation and in particular the set of instructions needed to rebuild a new library and to use it.
