Compiling Delila Programs with GPC

The Delila programs can be compiled using the GNU Pascal Compiler (gpc). With the advent of the GPC compiler Pascal programs will run on most machines. GPC is quite powerful and can be used for system functions, although the Delila programs do not take advantage of this.

As of the latest release GPC will now work on Delila programs!

Any program that uses the getdatetime routine to stamp output with the date and time must have the correct version of that routine. You must replace the time package with the correct one.

Script for Compilation

I have written a script to compile using GPC: gpcc. The main features of the script are that it sets several flags:

  1. --standard-pascal This works for all programs that do not have date/time calls. The script will detect the use of time functions and automatically remove this option if needed.
  2. --transparent-file-names This flag is set on so that file names given in the program map directly to the local file directory names. This allows the user to have, for example, a makelogop file and the makelogo program will automatically read it. Without this flag on, the user would have to type the file name for every run, which is tedious and makes scripts just about useless.
  3. --no-mixed-comments This flag is required because sometimes I will use a bibtex format reference or other things, and these have {} which are Pascal comments.
The gpcdebug script will GPC compile in debug mode. Then it launches gdb for finding the location of the problem.
