StringUtils, FileUtils
by Frank Heckenbach 31 May '02

31 May '02

Hi, in the current GPC version, I've included a StringUtils unit for general string handling routines (on a higher level than the built-in and RTS routines). Up to now, it only contains routines for a string hash table, but I'm planning to add some more routines. Perhaps some of you also have some routines to contribute (or features to request). Conditions for inclusion into this unit should be, IMHO: - Generally useful (not meant specifically for a certain program or something), - self-contained (not relying on an external library etc.), - new functionality compared to the existing routines (whereas the same or similar functionality under a different interface for compatibility purposes should go into other units, like GPCUtil for compatibility to `Turbo Power' units), - and, of course, compilable with the current GPC version, portable, bug-free, etc. ;-) The same goes for the FileUtils unit which has been there for some months already.

If you can repeat it, compile with another Extended Pascal compiler, for example Prospero's one. If that fails too, there is really something wrong with the code. But I suspect gpc.

operators pow and **
by Maurice Lombardi 01 Feb '02

01 Feb '02

Hi all, It seems that operators pow and ** cannot be redefined in gpc. Is that expected ? I work with djgpp / w98 dos box (should be irrelevant I think) Thanks Maurice -- Maurice Lombardi Laboratoire de Spectrometrie Physique, Universite Joseph Fourier de Grenoble, BP87 38402 Saint Martin d'Heres Cedex FRANCE Tel: 33 (0)4 76 51 47 51 Fax: 33 (0)4 76 51 45 44 mailto:Maurice.Lombardi@ujf-grenoble.fr

Hi Merry Xmas If you like to keep paper copies of your source files and would like to print on both sides of the paper you might like the attached source file. Also, it adds a margin for 3-hole punch. enjoy, Russ

Getting started ...
by j.logsdon＠lancaster.ac.uk 22 Dec '00

Hi This is always the most difficult part! I am porting a very old Pascal program written originally in Prospero Pro-Pascal and I want to use a (relatively) platform independent compiler. Hence gpc. So a few questions - I have already searched in the info pages (aka the 400+ page manual) and found the answers to some of my questions but: 1 A simple program like: program t(Input,Output); var s:string[20]; begin read(s); writeln(s); end. when compiled (and it works) still gives a message: /usr/local/lib/gcc-lib/i686-pc-linux-gnu/2.95.2/libgpc.a(randfile.o): In function `do_seek': /home/elug/pascal-wochenende-20000729/gcc-2.95.2/gcc/p/rts/randfile.c:327: the `llseek' function may be dangerous; use `lseek64' instead. I may be running this at the weekend (RH 6.2 but gpc --version gives 2.95.2 19991024 (release) rather than anything like 20000729) but is this possibly an installation problem? 2 Is there a way of taking the command line arguments into a program? eg for a program foo.pas that compiles to a.out, I want to access argument 1 as 'something' in: ./a.out something Is the whole command line available (like $0)? I saw the demo getopt but when I tried to compile this, I was told that it couldn't find GPC (from uses GPC). Does this mean that I haven't installed it properly? gpc is in the default place (/usr/local/bin/gpc etc) Hope my questions are clear TIA John

GLib-Unit
by Eike Lange 21 Dec '00

21 Dec '00

Hi! The GLib-Unit for Gnu-Pascal is available at ftp://agnes.dida.physik.uni-essen.de/~lange/ This unit provides: - singly and doubly linked lists, - hash-tables, - caches, - date/time - functions and much more. This unit is also basically needed to port gdk which is needed to port gtk :-) IMHO this unit is very useful for programmers, even without interest on the development of graphical user interfaces. Have fun with it. Eike

file descriptor problem
by nicolas bley 21 Dec '00

21 Dec '00

We currently face a problem porting pascal Oregon programs on GPC. These programs use files descriptors declared as global variables. These descriptors are declared in a module while they are used in another module. Trying to open one of these files in write mode (rewrite function), we get a strange error message: ?GPC runtime error: (gpc-rts) _p_initfdr() has not been called for file (#701) Does someone know how to manage file descriptors declared as global variables? (See included files for example). #ifndef VARIABLE #define VARIABLE module Variable interface; export Variable = ( GlobalFile,FileType ); type FileType = file of char; var GlobalFile : FileType; end. #endif #include "variable.ph" module Variable implementation; var GlobalFile : FileType; end. #include "variable.ph" program file_test; import variable; var Filename : string(20); procedure assign( var t : FileType; var name : string ); var b : Bindingtype; begin { assign } unbind( t ); b := binding( t ); b.name := name; bind( t, b ); b := binding( t ); end; { assign } begin Filename :='toto.txt'; assign(GlobalFile,Filename); rewrite(GlobalFile); end.

Internal compiler error
by Tom Verhoeff 17 Dec '00

17 Dec '00

I received the following error: gpc -Wall --executable-file-name --automake --unit-path=/home/wstomv/projects/yahtzee/units --unit-destination-path=/home/wstomv/projects/yahtzee/units testdriver.p testdriver.p: In function `Testgamestatistics': testdriver.p:39: Internal compiler error in `contains_file_p', at util.c:1542 Please submit a full bug report. See <URL:http://www.gnu.org/software/gcc/faq.html#bugreport> for instructions. make: *** [testdriver] Error 1 The URL refers to a page that has moved and is for gcc, not gpc. What is the thing to do? The program that causes this is not so small (thousands of lines), and I don't feel like locating the error unless it is really helpful. By the way, I use gpc version 20001122, based on 2.95.2 19991024 (release) Greetings, Tom
