Question: How do I run gpc?

Answer: 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. GPC uses command-line options to guide the compilation. These options are often very standard, such as -c to avoid linking and produce only object files, -O# to specify optimization levels, -o to specify the name of the output (executable of object) file. Almost all options are documented in HTML format. For a complete list, obtain the GNU Pascal Manual . There are no useful Unix man pages for this compiler. Because of its close relationship with the GNU C-compiler GCC, almost all of the options that are available for the latter are also part of the Pascal compiler command set. Another effect of this is that there is usually no problems with using C-routines in conjunction with the Pascal compiler. This comes in handy when you are trying to compile Pascal programs to run in parallel mode on a multi-processor system
