[Fwd: 16 bit sets?]
by Sven Jauring 03 Aug '01

03 Aug '01

Hi again! I need to be able to specify not only 16 bit sizes but also 8 bit and 4 bit sizes as well. Is there anyone out there that could give me a hint of HOW to implement the functionality in GPC and some kind of estimation of how long TIME it would take?

Date: Tue, 31 Jul 2001 16:34:50 +0200 From: Sven Jauring <sven.jauring(a)hiq.se> To: gpc(a)gnu.de Hi, I'm working in a project, where I need to compile old pascal code using GPC (beta 20010201). The code is scattered with variable types, that depends on bit correlations in unions. E.g: ******************************** type INT0_255 = packed 0..255; BITS = (BIT0,BIT1,BIT2,BIT3, BIT4,BIT5,BIT6,BIT7, BIT8,BIT9,BIT10,BIT11, BIT12,BIT13,BIT14,BIT15); var VARIABLE1 : record case int16 of 0: (WORD: INTEGER); 1: (MSB: INT0_255; LSB: INT0_255); 2: (BT : set of BITS); end; ********************************* In order for this declaration to function properly, I seem to need the possibility to specify 'BT' to be just 16 bits, and not 32 bits, which seems to be default. I tried to find out from the manual if this is possible. I found the following passages: "The Extended Pascal features still missing from GPC are ..., set types with variable bounds, ..." and "Planned features: Other types... *sparse sets; sets of arbitrary types ?? ???" For me, this is pretty deep water, so I won't take offence if you tell me to RTFM, but never the less... My question is this: Can it be done in the latest release (20010623) or should I wait for someone to implement this feature? Best Regards Sven Jauring

calling c code from pascal
by Miguel Pérez E 02 Aug '01

02 Aug '01

Hello, sorry if this is a trivial question. I´d like to use dzcomm library in my pascal program. It is necesary to first initialize allegro: ///****************************************// program Terminal; {$L c:\djgpp\allegro\src\allegro.c} function allegro_init() : integer; asmname 'allegro_init'; external; begin allegro_init(); Writeln('Hola, esta es una prueba.'); readln; end. ///****************************************// but the gpc says: C:\DJGPP\allegro\dzcomm\term>gpc term2.pas --autobuild term2.pas:5: parse error before `)' term2.pas: In main program: term2.pas:8: parse error before `)' term2.pas:8: warning: function call as a statement - value is ignored What I am doing wrong?, or what switches do I have to set? Thank you for your help. Miguel Pérez E Development Engineer Primestone E-Mail: miguel.perez(a)primestone.com Tel: (571) 6265432 Fax: (571) 6156377

Automatic gpc installation
by Ernst-Ludwig Bohnen 02 Aug '01

Hi gpc fans, I think many people are bullfighting with gpc-installation on various platforms, me as well. It's a hard job. Hence I decided to write a tool trying to do all the work from scratch automatically. The tool (install.gpc) is intended to work for UNIX/Linux systems: System Status ----------------------------------------------- Linux SuSE 7.2 OK Linux SuSE 6.3 OK, makeinfo ver. 1.68 didn't work, needs 4.0 SunOS See URLs below IRIX See URLs below, same problem as for SunOS HP-UX Wrong make version, delayed AIX Not tested up to now, delayed The current status is that install.gpc seems to work fine only on Suse 6.3 & 7.2. Initial problems were due to an outdated makeinfo. Everybody who is interested may download the tool from: http://www.desy.de/~bohnen/gpc/install.gpc make it executeble and try it out (first time I recommend to do it as a simple user). Simply type: install.gpc <RET> to install gpc from scratch (default is pgc-20010623 with gcc-2.95.2). Type install.gpc -h for how to modify defaults and control verbosity, etc. Have a look on pre/post mortem log files written by install.gpc. http://www.desy.de/~bohnen/gpc/install.log.SUN http://www.desy.de/~bohnen/gpc/install.log.IRIX http://www.desy.de/~bohnen/gpc/install.log.HP-UX (no gmake) Maybe there is somebody who knows the reason for abnormal end of installation. Hints and suggestions are welcome to make install.gpc run more successful on those systems. Ernst-Ludwig
