16.3 Using an Ada Library

In order to use a Ada library, you need to make sure that this library is on both your source and object path Search Paths and the Run-Time Library (RTL) and Search Paths for gnatbind. For instance, you can use the library "mylib" installed in "/dir/my_lib_src" and "/dir/my_lib_obj" with the following commands:

     $ gnatmake -aI/dir/my_lib_src -aO/dir/my_lib_obj my_appl \
       -largs -lmy_lib

This can be simplified down to the following:

     $ gnatmake my_appl

when the following conditions are met:

"/dir/my_lib_src" has been added by the user to the environment variable "ADA_INCLUDE_PATH", or by the administrator to the file "ada_source_path"
"/dir/my_lib_obj" has been added by the user to the environment variable "ADA_OBJECTS_PATH", or by the administrator to the file "ada_object_path"
a pragma linker_options, as mentioned in Creating an Ada Library as been added to the sources.
