Incorrect version display
by Bernhard Tschirren 09 Aug '97

I have installed GPC-970714 for DJGPP. However, typing 'GPC -v' at the command prompt shows the following information: Reading specs from e:/djgpp/lib\specs gpc version 970624(2.7.2.1) WRONG VERSION! What happened? Cya L8r ________________________ | _) | | e-mail: bernie(a)icenet.com.au |___)ernhard |_|schirren ptschirrenb(a)cc.curtin.edu.au www: www.geocities.com/CollegePark/Quad/8070/

{$L} Good - but not good enough!
by Bernhard Tschirren 09 Aug '97

09 Aug '97

{$L filename} does not work with library files. For example {$L libgrx.a} does not work because GPC tries to link 'libgrx.o' !?

Size Of Objects - Revisited
by Bernhard Tschirren 09 Aug '97

09 Aug '97

You cannot use SizeOf with an object TYPE. See test program below: Type TObj = Object Constructor Init; End; Constructor TObj.Init; Begin End; Var O : TObj; Begin O.Init; WriteLn(SizeOf(O)); { This Works (Only after Init) } WriteLn(SizeOf(TObj)); { This calls Abort! } End.

Objects Bug
by Bernhard Tschirren 09 Aug '97

09 Aug '97

After hours of frigging around with HUGE test programs, I accidentally stumbled on a stupidly simple test program! Even better - it crashes the compiler! I only hope that you can reproduce the bug. I am using GPC-970714 for DJGPP in a Win95 shell. The following command line was used to create the files in OBJBUG.ZIP: redir -e error.out gpc -c bug01.pas --automake Bye ________________________ | _) | | e-mail: bernie(a)icenet.com.au |___)ernhard |_|schirren ptschirrenb(a)cc.curtin.edu.au www: www.geocities.com/CollegePark/Quad/8070/

Ncurses expects a real zero terminated string. You can get around that by coding `x := x + chr(0)' in Frank's example above but I want the ncurses usage to be seemless (more or less) with as little calling overhead as possible. No problems with that, now that I know how to use AsmName. I will adopt the `foo' and 'cfoo' (where foo is pascal and cfoo is C) convention. Thanks for the comments! Ken L.

But it doesn't add a #0 terminator, so the result may be wrong, as in the following program: program x; {$x+} procedure p(x:pchar); begin writeln(x) end; var x:string(10)='abc'; begin x:='x'; p(x) end.

Since there are more bugs with `CString' in gpc-2.0, I suggest you to upgrade to gpc-970714. > [...] The way I understand linking to a C rtn like: > function cfoo(SomeNum : integer) : integer; C; > requires that I link a C library that contains a function called `cfoo'. Function CFoo ( SomeNum: Integer ): Integer; AsmName 'foo'; together with the Pascal version Function Foo ( SomeNum: Integer ): Integer; (* yields 'Foo' *) solves the problem.

Hi all, I have come across a problem (bug? feature?) trying to pass a string schema parameter to a procedure with a parameter defined as a __cstring__. Please note that I am still using ver 2.0 so if this is fixed in the newer version, let me know. Here is the problem: This program works: 8<-------------------------------------------------- program works1; (* GPC 2.0 *) procedure foo(abar : __cstring__); begin (* dummy proc *) end; var blab : string (200); begin blab := 'Test Me'; foo(blab); end. 8<-------------------------------------------- However, the following program does not. I get the following error when trying to compile: dwork1.pas: In function 'program_Dwork1': dwork1.pas:16:incompatible type for argument 1 of 'Foo' 8<--------------------------------------------- program dwork1; (* GPC 2.0 *) type aCString = __cstring__; procedure foo(abar : aCString); begin (* dummy proc *) end; var blab : string (200); begin blab := 'Test Me'; foo(blab); end. 8<------------------------------------------ Also, if I define a proc in a unit like: procedure foofoo(acstr : __cstring__); and call it from a different program like: foofoo(SomeStrSchema); I get the same error as above DWORK1.PAS program. ******************************************************* Regarding the Pascal -vs- C calling, I like your suggestion, Peter. I would much rather have the string variant be the default but provive the bare ncurses calls just in case. However, the naming may need to be like: pfoo() and cfoo(). The way I understand linking to a C rtn like: function cfoo(SomeNum : integer) : integer; C; requires that I link a C library that contains a function called `cfoo'. If I could specify a different C fcn name to link to ( I think this was discussed before) I could call the procedures almost anything! Thanks much!!! Ken L.

You can upload it to ftp://agnes.dida.physik.uni-essen.de/incoming. As far as I understand "on SB16.Can" this program is specialized to the DJGPP platform with a SB16-compatible sound card, correct? What are your licensing terms? GNU GPL/LGPL (recommended)? If you have a README for your program, we could place it next to it. > For instance I use GPC with rhide, when the new IDE is available ? You mean: a new version of RHIDE? I don't know. Ask Robert Hoehne at the DJGPP newsgroup, news://comp.os.msdos.djgpp. I am sending this e-mail twice: One to yourself and one to the GPC mailing list. Since the list is maintained manually, it is probable that you are not yet subscribed to it, but this will happen soon. Greetings, Peter Dipl.-Phys.

Hello ! First, I want to thank you for this AWEsome Pascal compiler, I love it ! secondly, I want to subscribe to the mailing list I have made a little program to play WAV file on SB16.Can I send it to you ? , if yes , where ? For instance I use GPC with rhide, when the new IDE is available ? I know your time is precious, so I can be eager. Thanks again and bye Patrice BOUCHAND
