Pascal (Language): Gnu Pascal Compiler
built 632 days ago
The Pascal compiler installed on the Sun Fire system of HPCVL is the Gnu Pascal Compiler (GPC). This is a public-domain compiler that has a great deal of extensions and compatibility features built into it, and is designed to be very portable. The versions are at present:

The first Pascal compiler was designed in Zurich for the CDC 6000 series mainframe computer family. Niklaus Wirth reports that a first attempt to implement it in Fortran in 1969 was unsuccessful due to Fortran's inadequacy to express complex data structures. The second attempt was formulated in the Pascal language itself and was operational by mid-1970. Many Pascal compilers since have been similarly self-hosting, that is, the compiler is itself written in Pascal, and the compiler is usually capable of recompiling itself when new features are added to the language, or when the compiler is to be ported to a new environment. The GNU Pascal compiler is one notable exception, being written in C.

This FAQ is not meant as a manual for the GNU Pascal Compiler. The usage of the compiler is very straightforward, though. The command gpc is used both for compiling and linking the programs. For linking, it will invoke the system-supplied ld feature with the appropriate switches and environment variables. To use GPC you have to have to have "/usr/local/bin" in your PATH. It might in some cases be necessary to set the system environment variable LD_LIBRARY_PATH to "/usr/local/lib:/usr/lib" in order for your executable to find the proper dynamic libraries at runtime.
