| Usage of Ada binding package files | ||
|
|
||
| There are three Ada binding package files under this directory: | ||
| cbea_map.ads, libspe2_types.ads and libspe2.ads. The cbea_map.ads and libspe2_types.ads declare data types, data structures and constants used in libspe2 API. The libspe.ads defines all interfaces of libspe functions using Ada pragmas. | ||
|
|
||
| To include the package files in Ada source file: | ||
| with cbea_map.ads; | ||
| with libspe_types.ads; | ||
| with libspe.ads; | ||
| Further more to have full visibility of the data and interfaces: | ||
| use cbea_map.ads; | ||
| use libspe_types.ads; | ||
| use libspe.ads | ||
|
|
||
| The Ada binding package files are installed under /usr/adainclude in SDK 3.0. | ||
| You need to set this directory in your source path so that the compiler could find the packages. | ||
| For instance in your GNAT project file hello.gpr: | ||
| Project hello is | ||
| for Source_Dirs use("/usr/adainclude/", "."); | ||
| end hello; | ||
|
|
||
| When compiling the Ada source program, add a GNAT option -Phello.gpr. | ||
| e.g. | ||
| ppu-gnatmake helloworld.adb -Phello.gpr | ||
|
|
||
| The libspe2.ads file is linked with libspe dynamic library automatically through Linker_Options pragma. |
