gnu p compilation on redhat variant
by Patrice Seyed 17 May '05

Hi, As following instructions at: http://www2.gnu-pascal.de/gpc/Compiling-GPC.html#Compiling-GPC In terms of creating symlink to unpackaged "p" and so forth, and the configure line with --enable-languages=pascal, when I then do the "make" I get the following errors at the end: p/declarations.c: In function `mark_binding_level': p/declarations.c:1587: `shared_decl_lang_specific' undeclared (first use in this function) p/declarations.c:1587: (Each undeclared identifier is reported only once p/declarations.c:1587: for each function it appears in.) make[1]: *** [p/declarations.o] Error 1 make[1]: Leaving directory `/home/apseyed/software/gcc-3.2.3/gcc' make: *** [all-gcc] Error 2 Any help appreciated. This is a system based on RHEL 3. I tried the gpc rpm binary that runs on rh 6 and received the error: ld: cannot open crtbegin.o: No such file or directory Thanks, Patrice Seyed Linux System Administrator - LinGA RHCE, SCSA Boston University Medical Campus

types for ncurses
by willett 17 May '05

17 May '05

Frank Heckenbach: Apologies for duplication, but you replied to subsequent messages and a copied part of this one, so I'm guessing you didn't see the questions below. I'm responding to your complex (to me) message about ncurses types and automatic configuration for multiple hosts. Any verification or correction of my approach would be appreciated. Earlier Message from willett(a)udel.edu: Frank, thanks very much for all your advice. I'm trying to get up to speed here. Ok, based on your message, I'm now using: MedCard for chtype in ncurses.h (assuming typedef unsigned long chtype) CBoolean for "bool" in ncurses.h (assuming typedef unsigned int bool) CBoolean for an "int" which contains only TRUE or FALSE CInteger for an "int" used as an integer (on older gpc I use "integer") tacs now uses index of char128 = #0 .. #127 The c translation types are very useful! Thanks. Did I understand you to say I should use CBoolean in both the above cases? To create the ncurses.h file, I have to run ./configure within the ncurses source directory. I could run this several times for different hosts, to find what the range of types are. Right? Could you suggest a couple of different hosts to try out? Say, the most common? or perhaps, the most different? or better, how do I read the configuration file directly? I see that "configure" is a readable text file, but I can't find a list of alternative "bool" (for example) definitions in that configuration file. In fact, I can't figure out what my own host (Mac OSX) is called, when I try ./configure host=powerpc-apple-darwin I get an "unknown host" message. Any suggestions? When you said: > BTW (unrelated), I'd suggest to rename the package to > `gpc-ncurses-...' or `ncurses-gpc-...', to avoid confusion with an > ncurses library package. Did you mean I should name the interface file, e.g. ncurses.pas -> gpc-ncurses.pas or the unit, e.g. unit ncurses; -> unit gpc-ncurses; (If the latter, wouldn't gpc_ncurses be a more standard Pascal name than gpc-ncurses?) To do more things like reading the ncurses.h headers and then automatically configuring ncurses.pas types to be consistent, that's a bit beyond me. Beyond, both in that I wouldn't know how to and that I don't have time to learn how to and test all these. I wouldn't want to write c wrappers, a lot of work and then we're stuck with double calls. What I'm thinking now is to use all your MedCard, CBoolean, etc types, and put in documentation warning about what types of hosts would need edits before use. and/or how to check ncurses.h and hand-modify ncurses.pas. Does this approach and the above modifications seem reasonable? Willett Kempton

Internal gpc compiler error
by Angelo.Fumagalli＠alcatel.it 16 May '05

Hello, running gpc testsuite (gpc version 20041218, based on gcc-3.2.3) on x86_64-unknown-linux-gnu environment we have as result that 78 tests failed, some are related to an Internal compiler error on the same file: Internal compiler error in classify_argument, at config/i386/i386.c:1841 This internal compiler error was detected also compiling some of our own pascal modules ported under gpc. In attachment you find included the gpc testsuite log file. Some advise? Regards. Angelo Fumagalli

-mlong-double-128
by Adriaan van Os 13 May '05

The following produces an internal compiler error: [G4:~/gnu/testgpc/adriaan] adriaan% cat compare.pas program Compare; procedure R ( var r1, r2: real); begin if r1 <> r2 then r1:= r2 - 1.0 end; begin end.

If it's a gcc back-end bug, I can report it to Bugzilla. However, the "real" type used is 64-bit on the Darwin target, with or without -mlong-double-128 ... The option only changes the size of the "longreal" and "extended" types to 128-bit.

Re: Who uses Pascal?
by Garth Fletcher 11 May '05

11 May '05

I use it for a CAD system widely used in commercial Jacquard weaving (where the design is woven into the fabric) of upholstery, decorative and apparel fabrics, throws, etc. About 250,000 lines of code of which 96%+ is Pascal, a bit less than 4% assembler for bottleneck procedures. You may be wearing, sitting on, or wrapping yourself in something designed with a Pascal program... -- Garth Fletcher, JacqCAD International JacqCAD MASTER website: www.JacqCAD.com

Pascal Macro Compiler
by Contestcen＠aol.com 09 May '05

09 May '05

The first release of the Pascal Macro Compiler is now available. The Pascal Macro Compiler is a preprocessor or code generator for the Pascal language. It can generate Pascal expressions, statements, declarations, functions and procedures, up to complete Pascal programs. A small library of macros, such as a sort generator, is provided. The complete Pascal Macro Compiler User Manual is found online at http://www.pascalmacro.com I will make a few demo copies available at no cost. Frank Rubin

ProcPtr question
by Alain 07 May '05

07 May '05

Maxbe 'stupid' ... But I'm dealing with it ! ---------------------------------------- Type ptrRecord = ^theRecord; Type theRecord = record move : ProcPtr; hit : ProcPtr end; Procedure moveIt; Begin end; Procedure hitIt; Begin end; Procedure Init; Begin object^.move := @moveIt; object^.hit := @hitIt end; Procedure Run; Begin repeat with object^ do ???? Until ... End; ---------------------------------------- HOW can I make the actions point to moveIt and hitIt ? HOW is it possible to call the ProcPtr's procedures (Osx.3, GNU pascal) ? If you can help me, thank you ! Alain

ShortString
by Prof A Olowofoyeku (The African Chief) 06 May '05

06 May '05

Hi Would it be possible to predefine "ShortString" in GPC? (as "String [255]"). I appreciate that GPC doesn't yet have longstrings so this may seem pointless - but I can't see any harm in having ShortString already defined (at least, in Delphi mode). Thanks. Best regards, The Chief -------- Prof. Abimbola A. Olowofoyeku (The African Chief) web: http://www.greatchief.plus.com/
