If you can repeat it, compile with another Extended Pascal compiler, for example Prospero's one. If that fails too, there is really something wrong with the code. But I suspect gpc.

GNU Pascal 2.0 is released
by Peter Gerwinski 19 Dec '96

19 Dec '96

Hello, everybody! GNU Pascal 2.0 is released. The source and binaries are both on kampi.hut.fi and on agnes.dida.physik.uni-essen.de. On agnes we will provide experimental versions in `beta' and `alpha' subdirectories in addition to the "official" version, that's the only difference between the stuff on both sites. The announcement will appear in the NewsGroups, soon. Enjoy, Peter e-mail: peter.gerwinski(a)uni-essen.de home address: D\"usseldorfer Str. 35, 45145 Essen, Germany WWW: http://agnes.dida.physik.uni-essen.de/~peter/

BGI2GRX - README.TXT
by Sven＠rufus.central.de 19 Dec '96

19 Dec '96

BGI2GRX ======= BGI2GRX is based on GRX and BCC2GRX and only runs by using these libraries. Pay attention to the authors copyrights. BCC2GRX is an interface library for GCC written by Helmut Schirmer which allows to access the GRX20 library by using Borland's BGI syntax. GRX20 is a useful collection of graphics functions written by Csaba A. Biegl. With BGI2GRX I give GPC users access to those functions with Gnu PASCAL. BGI2GRX was tested with: GPC 2.0 (DJGPP), GRX 2.0 (dated 04/96) and BCC2GRX 2.0 (dated 10/96) in plain DOS and in the Win 95 DOS box. GRX20 and BCC2GRX are made to compile under LINUX so I assume that BGI2GRX should compile and run flawlessly on a Linux box but haven't tested it yet. !!! CAUTION !!! --------------- For displaying text in graphics mode BCC2GRX requires you to set an environment variable "GRXFONT" which points to the path where GRX fonts are installed in. You have to set the environment variable "GRX20DRV" to use different graphics drivers. For details read the GRX documentation. I only ran GRX programs on VESA compatible graphics cards and they worked without "GRX20DRV". The graphics functions which use fill style and/or line style settings only work with their default settings. This is because the required functionality is not yet available in GRX 2.0. You can set different settings but these are simply ignored. Authors and sources of suply of GRX20 and BCC2GRX ------------------------------------------------- GRX20 : csaba(a)vuse.vanderbildt.edu (Csaba A. Biegl) ftp://ftp.simtel.net/pub/gnu/djgpp/ BCC2GRX : hsc(a)techfak.uni-kiel.de (Hartmut Schirmer) ftp://ftp.simtel.net/pub/gnu/djgpp/ http://www.techfak.uni-kiel.de/~hsc/BCC2GRX/ The demos --------- All demos (except Colors.pas) were tested with GPC as well as with Borland Pascal. Noticable are the speed differences (especially with 8 bit color depth) and the good compatibility (except FillStyle and LineStyle). I noticed that some "special" BGI drivers (e.g. VESA.BGI) swap AndPut and OrPut functionality when using PutImage. History ------- 12/96 - first release Future plans ------------ - same unit for DOS (DJGPP) and Linux (SVGALIB, X) - improve compatibility Thanks to: ---------- Hartmut Schirmer and Csaba Biegl for their help Peter Gerwinski for his patience and his short-term changes to GPC Ralf Meyer for his help on the readme translation Have fun with GPC, GRX, BCC2GRX and BGI2GRX !!! Sven Hilscher mailto: sven(a)rufus.central.de Any feedback is welcome (criticism, suggestions, assistance).

gpc v2: works on Sony newsos
by Utz-Uwe Haus 18 Dec '96

18 Dec '96

Hi, --- just to give a positive status report: gpc compiled without problems on a m68k-sony-newos machine. I only ran a few checks from the test/ dir, but those were okay. The compile for mips-sony-newsos is currently running. Is there any place where I can find the testsuite that is references in one of the docs? Keep up the good work, Utz

Final prepares releasing GNU Pascal 2.0. Please check.
by Peter Gerwinski 12 Dec '96

12 Dec '96

Hello, everybody! We are now ready to release an improved version of what you know as gpc-1.2-2.7.2 as a new official version, GNU Pascal 2.0. The announcement below will go to the NewsGroups tomorrow or so. I am now setting up the directory tree on ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/ Please imagine it were ftp://kampi.hut.fi/jtv/gnu-pascal/ and check whether everything is set up correctly. The directory tree will be copied to kampi.hut.fi together with the announcement going to the NewsGroups. There is also a new home page which will replace the current one. You can check it now at http://agnes.dida.physik.uni-essen.de/~gnu-pascal/new/ :-) , Peter 8< --------------------------------------------------------------------------- Subject: ANNOUNCE: GNU Pascal 2.0 (2.7.2.1) Newsgroups: comp.lang.pascal.misc, comp.lang.pascal.borland, comp.lang.pascal.ansi-iso, comp.os.msdos.djgpp, gnu.announce, gnu.gcc.announce Followup-To: comp.lang.pascal.misc Summary: GNU Pascal version 2.0 (GCC 2.7.2.1) now available Keywords: GNU,Pascal,Free Software,FreeWare This is the announcement of version 2.0 of GNU Pascal corresponding to GCC version 2.7.2.1. What is GNU Pascal? =================== GNU Pascal is, as the name says, the Pascal compiler from the GNU compiler family. This means: - 32 bit compiler, no limits, highly optimizing, - runs on all operating systems supported by GCC (including DOS, Win95/NT, OS/2, Linux, FreeBSD, many other Unix dialects), - Free Software according to the GNU General Public License, - compatible to other GNU languages and tools such as GNU C and the GNU debugger. The compiler integrates the following language standards: - ISO 7185 Standard Pascal, - ISO 10206 Extended Pascal (90% implemented), - Borland Pascal (80% compatible). Some highlights: - From Extended Pascal: complex numbers, initialized variables, structured function return values, modules, - from Borland Pascal: inc, dec, shl, shr, absolute variables, units, objects, - GNU extensions: min, max, (PXSC-style) user-definable operators. Disadvantages: - Pascal support in integrated development environments (RHIDE for DOS/DJGPP, (X)WPE for Unix) is still beta, - the GNU debugger (gdb) does not yet understand Pascal syntax and types, - few standard libraries (can use C standard libraries instead), - longer compilation times than with e.g. Borland Pascal. New features in version 2.0 =========================== - Borland extensions are integrated into the main distribution line. - Easier to compile. - Texinfo online documentation (available as HTML, too). - Precompiled Module/Unit interfaces. - Automatic `make' facility. - Some bugs fixed. "Export foo = all" extension. Machine attributes. Etc. Where to obtain GNU Pascal ========================== The master ftp site for GNU Pascal is kampi.hut.fi. The source of the compiler, binary distributions for certain platforms and other GNU Pascal related files can be found in ftp://kampi.hut.fi/jtv/gnu-pascal/ . This site is mirrored on ftp://sunsite.doc.ic.ac.uk/gnu/pascal/ . Other sources of information ============================ More about GNU Pascal can be found in our WWW home page, http://home.pages.de/~GNU-Pascal/ . If you have problems to access this, try http://agnes.dida.physik.uni-essen.de/~gnu-pascal/ . That page contains the GNU Pascal FAQ list and an online version of the complete documentation. If you have questions or want to discuss about GNU Pascal, please join the GNU Pascal mailing list by writing to gpc-request(a)hut.fi . The address of the list itself is gpc(a)hut.fi . -------- Follow-ups will be directed to comp.lang.pascal.misc. Enjoy, The GNU Pascal Development Team Jukka Virtanen Peter Gerwinski Jan-Jaap van der Heijden

Re: I have a small Problem with GPC

Hello, Gareth Harper! > GPC112b.ZIP This was 730k and does not seem to want to compile any of > my programs giving me an error after the first line in my program. > (parse error Ithink) GPC112b.ZIP is a 1.1 (2.6.3) version without any Borland compatible extensions. Your program is probably correct for Turbo Pascal 6.0, but that version of GNU Pascal is a pure ISO Pascal compiler. The 1.1 (2.6.3) version *with* Borland extensions is in TURBO11b.ZIP. > GPC272b.ZIP a 1.0Mbyte file that I had to download twice as one of > the files I downloaded was a bad zip (It was from > Sunsite.Doc.Ic.AC.UK) and This gives me quite a few errors if I > compile with the -c option. It says nothing just accesses the disk a > lot If I use no options. That's interesting because GPC272b.ZIP is a *beta* version 1.2 (2.7.2) of GNU Pascal which should not be mirrored at Sunsite ... however I find it acutally more stable than GPC 1.1 (2.6.3), so it is indeed the best choice for you. ;-) > Do I need any other files to be able to use GPC. I own a Pentium > 60Mhzwith 8Mb ram. You need at least the GNU assembler and linker ... please look into the GNU Pascal FAQ http://agnes.dida.physik.uni-essen.de/~gnu-pascal/gpc-faq.html for more about the DJGPP version of GNU Pascal. > I currently use Turbo Pascal Verion 6.00. Could > you help me out please. If it gave me errors about sytnax then I > would be ok. But it does not like the type 'Word' GNU Pascal is only partially Borland compatible and is *not* a drop-in replacement for Turbo (Borland) Pascal. Differences between Borland and GNU Pascal are documented in the section "From Borland Pascal to GNU Pascal" in the documentation, http://agnes.dida.physik.uni-essen.de/~gnu-pascal/gpc-doc.html . Especially, GNU Pascal doesn't know `Word'. Try the following: Type (* Integer has 4 Bytes *) Word = __unsigned__ Integer; (* 4 Bytes *) ShortInt = __short__ Integer; (* 2 Bytes *) ShortWord = __unsigned__ ShortInt; (* 2 Bytes *) ByteInt = __byte__ Integer; (* 1 Byte *) Byte = __unsigned__ ByteInt; (* 1 Byte *) > [...] > > I seem to remember reading somewhere that I need GCC to be able to > compile with this. This is not the case. See the FAQ for details. Hope this helps, Peter
