Hi all. I'm trying to compile latest gpc 20011222 snapshot for Mandrake, which ships either gcc-2.96 and gcc-3.03. Latest message on this topic (early december) says gpc is not supported on these versions. Is this still true ?

In terms of the gcc sources that you use to build GPC, yes - you should use gcc-core-2.95.x sources for that. In terms of the compiler used to build GPC, you can use 2.96 or 3.03. I would advise you to use 2.96, since it is probably more tweaked and stable under Mandrake.

I should have precised i'm building a mdk package, not just installing it on my box. Anyway, i took the 'official' gpc rpm found on gnu-pascal ftp site, and adapted it to current gpc-20011222 and gcc-2.95-3. However, some things have changed: - there is now only one gpc binary, where they were epc, bpc, gpc and pc before - i had to add the following files and directories to make units work: %{_prefix}/lib/gcc-lib/%{gcc_target_platform}/%{gcc_version}/cpp0 %{_prefix}/lib/gcc-lib/%{gcc_target_platform}/%{gcc_version}/cc1 %{_prefix}/lib/gcc-lib/%{gcc_target_platform}/%{gcc_version}/include %{_prefix}/lib/gcc-lib/%{gcc_target_platform}/%{gcc_version}/units - gcc-cpp seems to be called gccpp now Off course, if you're interested in the spec file, i can send it back :-)

Everything now seems to be fine, however, CRT extension doesn't work -( [guillaume@silbermann 301]$ cat test1.pas PROGRAM Test;

BEGIN WRITELN('Hello World'); END. [guillaume@silbermann 301]$ cat test2.pas PROGRAM Test; USES CRT;

BEGIN WRITELN('Hello World'); END. [guillaume@silbermann 301]$ gpc --automake test1.pas -o test1 [guillaume@silbermann 301]$ ./test1 Hello World [guillaume@silbermann 301]$ gpc --automake test2.pas -o test2 [guillaume@silbermann 301]$ ./test2 (nothing)

So, what going wrong there ? My ncurse version is: [guillaume@silbermann 301]$ rpm -qa | grep curse ncurses-5.2-17mdk libncurses5-5.2-17mdk libncurses5-devel-5.2-17mdk

I don't know. I've heard that some versions of some distributions (mostly RH, but perhaps also Mandrake) ship with a broken version of ncurses, but I don't know the details ATM. Does it make a difference if you try it on the console or in an xterm? Do other ncurses programs work?

Actually, you're right, everything is OK on console. Except accentuated characters, but that's another problem :-) I also RTFM, and i found deep in info page that the -DX11 switch was needed for using CRT under X11. However, compilations fails for missing files: [guillaume@silbermann guillaume]$ gpc --autobuild -DX11 test.pas In file included from /usr/lib/gcc-lib/i586-mandrake-linux-gnu/2.95.3/units/crtx.c:35: /usr/lib/gcc-lib/i586-mandrake-linux-gnu/2.95.3/units/crtc.c:62: xcurses.h: Aucun fichier ou r?pertoire de ce type/usr/lib/gcc-lib/i586-mandrake-linux-gnu/2.95.3/units/crtc.c:63: xpanel.h: Aucun fichier ou r?pertoire de ce type gpc1: gpc exited with status 1 gpc1: gpc exited with status 1

I checked, thos xcurses.h and xpanel.h doesn't exist neither on my current system, nor in any available mandrake package....

All ncurses programm works well, AFAR (make menuconfig, for instance).

with crt you need to open a window to write to it. try this:

program hello; uses crt;

var Awindow : winstate;

procedure InitWindow; begin textbackground( blue ); textcolor( lightgray ); makewin( Awindow, 1, 1, 30, 10 ); fillwin( ' ', textattr ); end;

begin Initwindow; writeln('hello world'); end.

Yes.

Well, I don't think all that is necessary if the compiler is installed correctly (at least, it all works here, without my fiddling with the specs file). Perhaps this is all because you are building and mdk?

Strange. Doesn't work here either. I have never noticed this before (probably because I haven't used crt under linux). However, I don't remember any problem with crt coming up when I ran the testsuite. Mandrake is based on RH and so may have the same bugs as RH. But I have also tested this on Redmond Linux, which is based on Debian, and the same problem exists there. Again, this didn't show up when I ran the testsuite.

Frank - is there a problem with the testsuite not showing up crt problems?

There is not 2.95.2 gcc package available, only 2.96 and 3.03, so i had to create a standalone gpc package. However, there is also a gcc 2.95.4 maintained for PPC, and i just had the maintainer agreement to use it also for gpc. I'll try this ASAP.

Same for me for crtdemo.pas

I build my GPC with 2.95.3 sources. The trick then is to do "make install" rather than "make pascal.install". That way, you get everything that GPC needs (including a C compiler) all in one package. That circumvents all the configuration problems - but it perhaps not the ideal way to do things.

If you don't already have GCC of the same version installed, I think it is the best way.

Is there a "make" target to install it like this? I think "pascal.bindist" only packages the GPC compiler. Perhaps we could add another one (e.g., "full.bindist")?

I suggested something like this in a mail on 10 Nov 2001, but since there were no replies to that mail, I assumed there was no interest.

I don't remember seeing that mail. In any case, I am interested now ;-)

I'm adding the targets `pascal.install-with-gcc' and `pascal.bindist-with-gcc' now. I put in the `-with-gcc' part explicitly (rather than `full' as you suggested) and put it also in the name of the archive generated for the bindist to make it very clear what it does. Otherwise we might get some complaints if we just overwrite GCC files ...

Maybe this is a silly idea, but... Did you run the example program in Konsole? If so, you can't expect it to do anything visible.

You're perfectly right, i just tested with rxvt and eterm. But

1. how did you guess i used konsole :-) ?
2. is there a reason why this doesn't work (and should be reported as a

bug to konsole maintainers) ?

I use xterm, not konsole - and it didn't work there either. Is there any reason why it shouldn't work with xterm? Best regards, The Chief --------- Prof. Abimbola Olowofoyeku (The African Chief) Email: African_Chief@bigfoot.com http://www.bigfoot.com/~african_chief/

That's not a bug, that's a feature :-) Konsole restores automatically the previous screen contents after the curses shut down (-> your example doesn't leave a visible trace). Moreover it buffers the screen output, so that rapid changes are merged together to reduce the load on X server (-> you don't even see a flash or something like that).

This should work though:

program Test (Input, Output);

uses Crt;

begin WriteLn ('Hello world!'); Write ('Press ENTER, svp... '); ReadLn end.

Arghh, the return of the evil readln at the end of the program :-) I used to instruct my students to use it with TurboPascal, as they were confused by automatic return to editing mode after completion of program execution, it seems i'll have to use it myself with konsole...
