GNU Pascal and X-Windows
by Brooker, Steve 25 Oct '99

25 Oct '99

I wish to port 250,000 lines of DEC Pascal code running on COMPAQ Alpha under OpenVMS/X-Windows to under Linux/X-Windows on Intel (and on Alpha if possible). I know that I will have some considerable problems with the non standard parts of DEC Pascal but GNU Pascal seems to be getting better all the time. The question I have is can I keep the same user interface, i.e. direct X-Windows and MOTIF calls from the Pascal code, i.e. is there an X-Windows/MOTIF binding for GNU Pascal. If the answer to this is yes please tell me. If it is not please tell me how GNU Pascal programmers develop GUI's.

[...] Okay, so GPC is unable to find your GCC. That's a minor incompatibility between a version of GPC and a version of GCC that does not match exactly. To work around, you can copy the GCC-related files (`cc1' etc.) somewhere under /djgpp/lib/gcc-lib/... from GCC's directory to GPC's one.

RHIDE problem
by Adam Naumowicz 25 Oct '99

25 Oct '99

Hello, I know that probably it is not the best list to write about it, but I know that most of GPC programmers use RHIDE, so I decided to ask you. I use RHIDE on Linux successfully, but trying to install it for my friend on RedHat 6.0 I encountered RTE at the first attempt to start the editor. There was a message like 'segmentation fault, unable to connect to a terminal' or something like that. Maybe it is a known problem, maybe there is some work-around. My friend uses RIVA TNT grafic card - maybe that is the problem ?

another trouble (it was: Beginner needs help)
by Nicola Girardi 25 Oct '99

25 Oct '99

hi again, this time it is because i tried to compile programs using "uses Crt" outside Rhide (i use it as my favourite IDE) this is the command line i typed (i found it somewhere in the FAQ): girardi@ux(tty4)~/devel$ gpc -g --automake -o foo foo.pas gpc: installation problem, cannot exec `cc1': No such file or directory gpc1: gpc exited with status 1 /usr/lib/gcc-lib/i486-linux/egcs-2.91.66/units/crt.pas:345: `/usr/lib/gcc-lib/i486-linux/egcs-2.91.66/units/crtc.c' could not be compiled gpc1: gpc exited with status 1 foo.pas:2: module `crt' could not be compiled so, what's up? my distrib. is Debian 2.1 (slink), and all dependencies are OK. but there's still something wrong. sincerely, -- Nicola Girardi girardi(at)keycomm.it Key fingerprint = CD 7D 57 C2 52 73 67 B5 13 48 AA 8C 3E 7F 13 DC

Beginner needs help
by Nicola Girardi 24 Oct '99

24 Oct '99

hi all, i'm going to start again programming under linux. all i had done before this was some programs for DOS (i've been using linux for just a year) with Borland Pascal. now in linux i'd like to start programming again, but there are some functions that i can't find, and that i can't implement. for example, i need something as "delay(milliseconds)" but i can't find anything similar. ok, in C, i'd use "usleep()", but what in Pascal? and, for example, again, "textcolor and textbackground" ? readkey? keypressed? and how to use Svgalib instead os DOS' BGI ? please help me ASAP. thanks in advance. -- Nicola Girardi girardi(at)keycomm.it Key fingerprint = CD 7D 57 C2 52 73 67 B5 13 48 AA 8C 3E 7F 13 DC

What I said is: This is only recommendable if you use CRT anyway. It's not a good idea to use CRT just for Delay, neither in GPC nor in BP. Just that BP does not offer any easy alternative, but GPC does (Sleep and SleepMicroSeconds in the GPC unit).

Hi 1) How do I pass '-Praw' to PrinterArguments? 2) Any particular reason why PrinterArguments isn't just a string? Thanks, Russ

Re: no subject (file transmission)

"S. Achterop IWI-120 3932" wrote: > The question of course is, does this ring a bell? Maybe... There is a known problem: : IRIX and AIX work stations (and wherever else): initializers are not : executed (GCC bug!) This affects unit/module initializers, but it seems that the call to _p_initfdr (which is called automatically for each file type variable) is done in the same way, even in the main program. As stated, this is actually a GCC problem. However, it is solved in gcc-2.95 by using a utility called collect2 (at least according to the docs -- I can't check it myself since I don't have access to a system affected). The next version of GPC will work with gcc-2.95, so perhaps this will already solve the problem. To make sure it's really this bug, you can try the following code. If it fails to write `foo', it's the bug... unit foo; interface implementation to begin do Writeln ('foo'); end. program bar; uses foo; begin end.

followup reset error gpc
by S. Achterop IWI-120 3932 20 Oct '99

20 Oct '99

To follow up upon the reset error I just reported, the command gpc --help yields: GNU Pascal version 19980830, based on gcc-egcs-2.91.57 19980901 (egcs-1.1 release), compiled Sep 26 1998 13:44:06. So maybe I should try a newer version? Sietse
