Ada System Certifier_1 1.0 Date/Time of Processing: Monday 30 May 1994 03:00:23Pm Overall Assessment of System: OK Notes from PAL Certifier: Not possible to certify this system. The source code is not Ada.
Paradise is a set of Ada packages intended to provide an interface to the Unix operating system, and more specifically to the communication routines, that are accessed via file descriptors. It lets the Ada programmer use files, pipes, and sockets, as well as signals, error codes, environment variables, etc..., using an interface that looks as much as possible like the C interface.
Paradise supports multi-tasking: any input or output is blocking for the calling task only, and not for the entire process.
Paradise is intended to be system-independant and compiler-independant; so far, it works on three environments:
It is known not to work well on SunOS/Alsys, because of problems on signal handlers;
For people who would like to port it to other environments, informations on portability are displayed inside the code. A programmer's guide should appear in future versions.
To install Paradise, you need:
Once you have checked all this, you need to edit the system.mk and compiler.mk files, to make them fit your environment. Default files are provided for SunOS and HP-UX systems, and Alsys and Verdix compilers.
NOTE: there are no Ada sources in the distribution; the source code must be first processed by m4 to become Ada code.
