BUG report for gpc-20010516.tar.gz
by Mirsad Todorovac 27 May '01

27 May '01

Dear Sir or Madam, I have to report a bug in your code which prevents your PASCAL compiler to be built unless -DEGCS -DEGCS92 and -DEGCS95 are all defined (using 2.95.3 back-end). This has not been set by ``configure'', so manual intervention was needed. I can't tell if defining -DEGCS97 would be better than not, but I was satisfied (as for now) with having a PASCAL running on the system!!! (alpha-dec-osf4.0b box, gcc-2.95.3 compiler suite, gmake, gsed) Fix: define "-DEGCS -DEGCS92 -DEGCS95" … [View More]

Thanks! (was RE: [Fwd: Re: Newbie question ...])

Many thanks for that clarification, Frank! As for the EXE compression by WDOSX, the documentation certainly suggests this is genuine compression, not simply stripping the symbol table ... :-) Best regards, Joe. > -----Original Message----- > From: Frank Heckenbach [SMTP:frank@g-n-u.de] > Sent: Friday, 25 May 2001 1:43 > To: gpc(a)gnu.de > Subject: Re: [Fwd: Re: Newbie question ...] > > da Silva, Joe wrote: > > > I have now tried WDOSX 0.96 and it works … [View More]with the GPC > > "Hello world" test program!

Old Bug: Global variable not initialised properly
by Ian Thurlbeck 24 May '01

24 May '01

Dear All After 2 years of using gpc I thought I'd better update to a newer release, so I have installed gcc-2.95.3 and gpc-20010512. It appears than an old bug has resurfaced. A global variable declared in a module is not initialised properly. The following code does NOT print out the string 'OK': -------main.h------------ var s: string(40); external; procedure print_globals; external; ------------------------- -------main.p------------ program main(input,output); #include "main.h" … [View More]

Good news! I have now tried WDOSX 0.96 and it works with the GPC "Hello world" test program! Not only did it convert the executable to a stand-alone application (built-in DPMI services), it also compressed the executable to nearly half it's original size! :-) OK, one final newbie question : The online documentation (http://agnes.dida.physik.uni-essen.de/~gnu-pascal/gnu.html) says that GPC can be used to compile "commercial, non-free" applications. Is this a modification of the standard GNU … [View More]GPL, or is this an interpretation of the GPL? The reason I ask, is that a number of people, including (I think) DJ Delorie (of DJGPP fame), have a different interpretation. I apologise if this question has been asked before, but no matter how many times I read the GPL or look at the information of the FSF and GNU, I just can't figure it out.

Thanks for the info., Maurice. WDOSX is a DOS-extender for NASM, TASM, MASM, Borland C, Borland Delphi, MSC, Watcom C, TMT Pascal and DJGPP ... home page : http://www.wuschel.demon.co.uk/ I have now downloaded the pmode13b archive, but when I follow the links for COFF, I reach a "dead end" (can't find domain) at : http://www.abwillms.demon.co.uk/prog/kernel2.zip :-( Anyway, it looks like a new version of WDOSX was released just last month, so I will try again with this release ...

Newbie question ...
by da Silva, Joe 22 May '01

22 May '01

Greetings. I hope I haven't missed the answer to this question somewhere (I have looked at the online information, but couldn't find it ...) : Is there a stub/extender available, for the DJGPP build of the compiler, that provides DPMI services for an application, instead of loading CWSDPMI? I tried stubbing the "Hello world" example using WDOSX, but this simply crashed the computer ... Regards, Joe.

reset() regression
by Ian Thurlbeck 21 May '01

21 May '01

Hello all I've just noticed a small difference with the gpc-20010512 compiler from the one I was using (gpc-19991030). If you do: program restest(input,output); var s:string(40); t:text; begin s:=""; {$i-} reset(t,s); if (IOResult = 0) then writeln('File exists') else writeln('File does not exist'); end. the 1999 compiled code produces "File does not exist" whilst the 2001 code produces "File exists". Not sure if you consider this worth fixing given I can test for "" before … [View More]
