Hello! Now I also have problems with the binding of external files to Pascal file variables ... I tried to use Extended Pascal "binding" to assign a file variable to an external -- existing -- file. I just copied the "Assign" pro- cedure by Berend as published in borland2ep.doc. It does not always work: I often get a runtime error saying that the file did not exist. (But it exists -- I can edit it, etc..) The only solution I could figure out: Mention each file in the program's header, forget about an "Assign" procedure, just reset it. Then you are asked for the external file name. Type it in -- voila. I defined a semi-dummy "Assign" procedure which prompts "please type in )-: myfile135.dat". It could not be done with "myexecutable <filenames.in", so I really must type in each filename by hand. This error is not reproducable. I have written some programs which can read files using Berend's "Assign", but not write. And vice versa. Currently, both does not work. What shall I do ???

GCC 2.7.x and GPC 2.6.3
by Peter Gerwinski 27 Nov '95

27 Nov '95

Hello, everybody! Somehow good news: GCC 2.7.x and GPC 2.6.3 *can* peacefully coexist on the same system. You just have to make the linuxaout-libraries visible for GPC (for example with the SlackWare 3.0 directory tree, use "gpc -L /usr/i486-linuxaout/lib myfile.pas") and to replace temporarily the new library libgcc.a by the old one. Only this one -- not the elf versions, and not libc.a, etc.. The linker will complain about some entry point, but the executable will work. I suggest to use an alias or a shell script for all that.

f2p, c2p
by Peter Gerwinski 24 Nov '95

24 Nov '95

Hello, folks! Only one small question/suggestion: Does there exist a f2p or c2p translator program which translates Fortran resp. C source to Pascal source? If not, I suggest that somebody writes it because of the following reasons: - Practical reason: It would be nice to import libraries written in C, C++ or Fortran automatically. For most purposes, it would be sufficient to have a program which ports C header files to Pascal Unit (Module) interfaces. - Psychological reason: The existence of a c2p would demonstrate that Pascal is at least as powerful as C. The existence of a p2c (which does in fact *not* support everything which is possible in Borland Pascal -- I am thinking of the Object extensions) is ac- cepted by many people as a "proof" that C would be superior to Pascal, so we should "proove" the opposite direction. :-) I am almost sure that at least the c2p program does not exist because Standard Pascal has indeed less abilities than C. However, you can do everything which is possible in C with GNU Pascal (including e.g. pointer arithmetics -- just do a type cast to Integer), so the main difficulty will be to *understand* the C source, not to translate it. C++ could be more complicated as long as GNU Pascal does not (yet) have multiple inheritance. For Fortran, I don't see any problems, since there are complex numbers in GNU (Extended) Pascal, but one should translate goto statements to structured statements wherever possible.. One idea how to write it: Just use the front-ends of the GNU compi- lers and replace the assembler back-end by a Pascal back-end. Once you have understood how the front-end passes information to the back-end, the job will be straightforward. (One could even easily generalize it to a general x2y translator ...! :-) I have not the time to do it myself :-( so I ask *you* if you are willing to do this important contribution.

I think there is yet another reason: When you want to do lo-level programming in Pascal, you *need* the Borland extensions. (Or, you must write large parts in assembler, which is also non-ISO.) And there are more examples where things can easily be done with Borland Pascal but are very uncomfortable or even impossible with Extended Pascal. > (Also, the object pascal language > looks nice and would be fun to support. Any volunteers? :-) The Borland "nonstandard" supports objects, so the object pascal language already *is* implemented in some sense -- I expect that only a few names must be changed. If a volunteer wants to imple- ment Object Pascal: It won't be too much work! Yours, Peter -------------------------------------------------------------------------------- Dipl. Phys.

Hi, I've downloaded the GPC binaries for Ms-dos, but I don't have an emx driver. Could you please point me in the direction to obtain these drivers for dos. I've searched the web, but can only find OS2 ones :(, so your help here would be much appreciated. Cheers Dave Smith

GPC and OS/2
by alland＠whidbey.com 23 Nov '95

23 Nov '95

Hello, I installed the version of GPC patched for emx running in OS/2. Has anyone made an OS/2 header file that works for API calls? Can someone show me a snippet of code showing how to incorporate an assembler procedure into a program? WriteStr doesn't work - "unresolved external". Writeln is sometimes called multiple times.

NEED LINUX/ELF VERSION OF GPC!!
by Arcadio Alivio Sincero 14 Nov '95

14 Nov '95

Can somebody PLEASE make an ELF version of GPC for Linux that works with GCC v.2.7.0???? Or give me some pointers on how to do it myself???? I downloaded the Linux version of GPC that Peter Gerwinski made, but it doesn't work on my system. I'm thinking maybe because I have SlackWare 3.0/ELF installed. When I first installed GPC, the compilation process would break when it came to the linking phase. ld, the GNU Linker, would say that it's unable to find file "crt0.o". I remembered seeing that file way back in my SlackWare 2.2 days, so kicked out the old SlackWare 2.2 CD-ROM and copied a "crt0.o" into my /usr/lib directory. Now, when I try to compile and link, I just get a whole bunch of unresolved reference errors. However, GPC itself appears to compile alright (except it produces a.out object files instead of ELF). It's just when it comes time to link that it goes haywire. Please help somebody! I need this compiler soon for a school project ... Arcadio
