Platform Specific Notes

Please refer to the table in Using Shared Object Files and Archive Files for platform specific instructions for building shared object files and archive files.

Digital Alpha

Quintus Prolog was revived for this platform in Release 3.4:

• 32 bit integers and pointers are used internally. However, the functions QP_get_integer() and QP_put_integer() take long integer arguments, and integer in the foreign language interface corresponds to long integers in foreign code. In the Structs package, the long type corresponds to long integers whereas the integer type corresponds to integers. Long integers are however truncated to 32 bits (sign-extended) by the Prolog system.
• In foreign code interfacing Prolog via the foreign language interface, pointers and long integers are assumed to occupy 64 bits. Hence, such code must be compiled in native mode, i.e. not using the cc option -xtaso_short. Furthermore, qld will link executables with the -taso option, so as to ensure that all pointers fit in 32 bits internally.

Silicon Graphics

Up to and including release 3.3, Quintus Prolog ran under IRIX 6.2 or later and used the O32 ABI. Later releases run under IRIX 6.2 or later and use the N32 ABI.

Sparc Solaris

Up to and including release 3.3, Quintus Prolog did not comply with the SPARC ABI; later releases do.

IBM RS/6000

Quintus Prolog was revived for this platform in Release 3.4, under AIX 4.3, and complies with the AIX 4.3 32-bit ABI.

HP-UX

Up to and including release 3.3, Quintus Prolog did not comply with the HP-PA ABI; later releases do.

Linux

Quintus Prolog was ported to this platform in Release 3.5, under Red Hat Linux 9, i.e. it requires glibc 2.3.
