According to Stephen Lindholm: > I believe that this should not compile with a warning. > [...] I fixed the bug. Below is the diff for gpc-parse.y. You need Bison to produce gpc-parse.c out of it and to compile GPC, but you can also ignore the warning or surround the passage it with (*$W-*) ... (*$W+*) to suppress the warning. The bug is not serious enough that we release new binaries, but it will be fixed in the next release, of course.

GNU Bulletin notes
by Peter Gerwinski 25 Jan '97

25 Jan '97

Hello! Some weeks ago, we were asked to write some notes about GNU Pascal for the GNU Bulletin. I do not know whether it is too late now, but here is a draft we could submit. Please post your comments/suggestions here as soon as possible, so we might get this into the January volume of the Bulletin. 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/ 8< ----------------------------------------------------------------- Forthcoming GNUs * Pascal GNU Pascal is a free 32-bit Pascal compiler. It is implemented as a Pascal front-end for GCC, the GNU compiler, thus it runs on all platforms supported by GCC and produces the same highly-optimized code. The current version 2.0 has passed all ISO 7185 level 0 conformance tests (but some problems on specific platforms where we suspect some general GCC problems), thus we consider it to be a valid level 0 Standard Pascal compiler. ISO 7185 level 1 is implemented, but not yet stable. Most of ISO 10206 Extended Pascal and Borland Pascal 7.0--including objects--is implemented plus some extensions from Pascal-SC (user-defineable operators) and native GNU extensions (e.g. min, max), but there is still a lot of work to do to fix all bugs, implement the missing features and improve the documentation. Any help is most welcome! The home ftp site of GNU Pascal is `kampi.hut.fi', directory `jtv/gnu-pascal/'. For more information, look into the inofficial `FAQ' in the `contrib' subdirectory. We also have a WWW home page `http://home.pages.de/~GNU-Pascal/' and a mailing list `gpc(a)hut.fi'. To get into the list, write an e-mail to `gpc-request(a)hut.fi'.

Next time, please correct it in the e-mail *before* you post it. The time I needed to correct your program would have been better spent on correcting the bug you are pointing me to. However, thanks for the bug report. It will be corrected in the next release.

Borland compatibility package
by Peter Gerwinski 25 Jan '97

25 Jan '97

Hello, everybody! I have written a small Borland comptatibility package for GNU Pascal on the DJGPP platform. It contains my "BPcompat" Unit, renamed to "System", a (new) "CRT" Unit, and Sven's "BGI2GRX" Unit, renamed to "Graph". There is no "Printer" Unit yet because it caused unexpected problems to write one, but the patched "libgpc.a" allows you to print by assigning a file to "prn", rewriting it, etc. The package is not portable but a DOS(DJGPP)-only solution, so I do not really recommend to use it for your new projects. However it might be useful for porting existing applications. It is available in the contrib subdirectory of the GPC distribution, i.e. ftp://kampi.hut.fi/jtv/gnu-pascal/contrib/bpcompat.zip and ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/contrib/bpcompat.zip. I am setting up a link from the GNU Pascal home page to it, too. Have fun, 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/

Apparent bug.
by Stephen Lindholm 24 Jan '97

24 Jan '97

I believe this is a bug. I believe that this should not compile with a warning. program testfile (input, output); var test: file of integer; i: integer; begin rewrite (testfile); for i := 1 to 10 do write (testfile, i); close (testfile); end. Compiled with: gpc -Wall -ansi -pedantic --standard-pascal -o testfile testfile.p If there are any typos, it is because I rekeyed the program. They would not actually exist in the program. The compiler tells me that ISO Pascal does not allow a file name parameter to reset/rewrite. I do not believe I am passing one to rewrite. I believe the warning refers to the barbarous practice of some compilers of requiring: rewrite (testfile, 'Test'); My mistake. Those testfiles in the program proper should be test. The program name is testfile. Please let me know if I am in error or when the bug will be fixed. (I'm not yet on the mailing list, so please forward a message directly to me.) Thank you.

Once this is complete, you can install GNU Pascal together with GCC typing a command like `make LANGUAGES="C Pascal"'. Then all GNU Pascal patches will already be in the GCC source; additional GNU f77 patches should not spoil them, so it will probably work. And in case the f77 team and others are working on similar projects, it can become `make LANGUAGES="C C++ Objective-C Pascal Fortran Ada Basic Foo Bar"', one day ...

Hello, everybody! I am thinking about setting up an archive with all postings to the mailing list in the last two years (i.e. during the time I am on the list). The archive could consist of some gzipped mail folders to be downloaded from the GPC WWW home page. Okay?

GNU Pascal and gcc/f77
by rodgers＠nlm.nih.gov 21 Jan '97

21 Jan '97

Dear Gnu Pascal Team, First, congratulations on your great efforts in bringing Pascal into the GNU compiler family. I have just briefly tried to build your latest gpc with gcc 2.7.2 with the GNU f77 patches applied. This results in an altered version for gcc of "2.7.2.f.1" which the gpc configuration file rejects as an inappropriate version. Do you have any plans to accommodate the simultaneous installation of f77 and Pascal? Any suggested work-arounds for my situation? Thanks and Best Regards, Rick Rodgers
