Debugging Pascal-code...
by Preben Mikael Bohn 29 Oct '02

29 Oct '02

Hi all... I am now trying to debug my code... However I have a problem with gdb... I have the following code: program hello; var testingint : integer; str : string; begin testingint := 432; str := 'Hello... '; writeln(str, testingint); end. I compile it with gpc -g -O0 --automake hello.pas --executable-file-name And run gdb with "gdb hello" I set a breakpoint at the start using "b hello.pas:6" and run it with "r". It stops fine, and when I have executed the next line (using "n") I try to print testingint using "print Testingint". But here I simply get "$1 = void"... What am I doing wrong here??? It prints out Str nicely (as a _p_schema-type, but I can live with that)...

Bug in GPC?
by Preben Mikael Bohn 28 Oct '02

28 Oct '02

Hi all, I have a *really* strage problem. In my main program I have the following code snippet: ... if ((currentEpoch <= endDate) and (currentEpoch >= startDate)) then begin err := computeResiduals( corrections, filters, gsObs, observationIndices, gsPos, gpsPos, currentEpoch, residuals, estimatedClocks, errorSats); ... This works fine. If I add a writeln such as this: ... if ((currentEpoch <= endDate) and (currentEpoch >= startDate)) then begin writeln('xxx'); err := computeResiduals( corrections, filters, gsObs, observationIndices, gsPos, gpsPos, currentEpoch, residuals, estimatedClocks, errorSats); ... then my function "computeResidual" suddenly fails????? What is going on? Does anyone have an idea? It should be noted that "computeResidual" does not read from stdin or anything... My gpc runs on linux ans is version 2.1 (20020510) based on gcc-2.95.2 19991024 (release). Best regards Preben __________________________________________________ Do you Yahoo!? Y!

Conformant array curiosity
by Wood David 25 Oct '02

25 Oct '02

Hi, I've been using conformant arrays in procedure declarations for ages, but recently I was given a troublesome module which had a number of procedure declarations, each with conformant parameters. When compiling the exported procedure, it actually caused our DEC Pascal compiler to crash (the stack dump suggesting it was whilst trying to build a conformant expression). Trying our faithful gpc 2.1 compiler, I got about 50 polite error messages "prior parameter's size depends on xyz" where xyz is a conformant array bound. However I can't figure out what has triggered this error. Can anyone shed any more light on how this may occur?

GPC on Darwin
by Adriaan van Os 22 Oct '02

22 Oct '02

As I am new on this discussion list, I have included some information about myself at the bottom of this message to introduce myself. My field of interest is GPC for Darwin (Darwin is Apple’s open-source kernel of MacOS X, based of FreeBSD 4.4 UNIX). I gathered the following relevant information: - the first version of GCC that fully supports Darwin is GCC 3.1 - GPC 2.1 is based on GCC 2.95 - GPC-20020910 alpha/beta has patches (diffs) for GCC 3.0 Consequently, my questions are: - has anyone on this list tried to build GPC for Darwin ? - has anyone on this list tried to build GPC for GCC 3.1 ? Regards, Adriaan van Os gpc(a)microbizz.nl --------------------------------------- About myself I run a small software company in The Netherlands named Microbizz. You are invited to laugh about my website at www.microbizz.nl. Currently, I am working mainly on CAD software and application toolboxes. Pascal is my language of choice. I have worked with the following Pascal compilers: DEC-10 (1978) DEC-10 Pascal Apple II UCSD Pascal Apple IIgs TML Pascal ORCA Pascal CPM Turbo Pascal 1.0 MS-DOS Turbo Pascal 3.0 upto 6.0 Windows Delphi Macintosh Turbo Pascal Think Pascal Apple Pascal for MPW Language Systems Pascal for MPW MetroWerks Pascal CodeWarrior Pascal Darwin See forward to work with GPC. What I most liked about what I learned from GPC was it’s ability to pass local procedures as actual parameters !!

procedure parameter defaults
by Nick Ioffe 22 Oct '02

22 Oct '02

Hi! In ADA and Vax Pascal there is a way of specifying default parameters: procedure a (x : integer := 10; y : string := 'abcdefg'); and to call a with specific argument: Var var1 : integer; var2 : string; Begin var1 := 5; var2 := 'hello'; a ( x := var1); a; a ( y := var2); a (var1, var2); 2 questions: 1. is there any way of doing so in GPC 2. if answer to #1 is "no" is it possible to include it in todo list Thank you in advance, Nick

Wishlist: asmname for constants
by Eike Lange 20 Oct '02

20 Oct '02

Hi Folks! Porting a library to a GNU Pascal Unit sometimes means putting a variable instead of a constant. Like this: foo.c: --------- int _c_konstant = DEFINED_CONSTANT_IN_C; --------- foo.pas: ----------- unit Foo; interface {!! Treat them as constant !!} var Konstant: Integer; asmname '_c_konstant'; external; implementation {$L foo.c} end. ----------- Doing it this way means a lack of using these "constants" in a "case" statement. It would be nice to have a feature like: const Konstant = _c_konstant; or similar. -- Eike Lange

Building an h8300-hitachi-hms cross-compiler under i686-pc-cygwin 32
by Hansen, John 17 Oct '02

17 Oct '02

I've tried to build a h8300-hitachi-hms cross-compiler to no avail under cygwin. Does anybody know if it is even possible? It dies when it tries to build the RTS (integer constant too large). Does anyone have pre-built binaries? Thanks, John Hansen

IDE mingw?
by Eike Lange 16 Oct '02

16 Oct '02

Hi! During our astronomy seminar at the university Essen/Germany, we need to do some programming work and I'd like to hand out a CD with GPC. Most of the students are using windows and are used to play with an Integrated Development Environment. Is there an IDE available for mingw32? Is there a _simple_(!!) install skript and a package available for GPC and mingw32? (just pressing "install" and all is fine?) Eike
