[fpc-pascal] Strange debugging issue
Hi all, When trying to debug a series of events in a program, parts of source lines disappear - apart from the fact that the execution secuence seems very off.

[fpc-pascal] Dosemu problems compiling
Hello all, After installing fpc 2.4.0 on a freedos directory, I had the following problems: - I tried to install using the install program, but dosemu crashed when clicking on 'Continue' - So I installed the base package manually, adjusted the path. Now fpc (without arguments) starts correctly, showing all the commandline options. Compiling a program (which compiled identically on Linux without errors), I get a load of errors about GOTO and LABEL not being defined. I recompiled with -Sg, and dosemu crashed again. I tried increasing DPMI memory (from 20 MB to about 50 MB), no difference. The dosemu output is below. Anyone had a similar experience? (NOTE: I tried dosbox too. When I ran 'fpc', the screen output was garbled. Tried several options, but couldn't get that to work). I'm trying to get a program compiled for use under DOS+extender (or win32). I looked up the possibility to cross-compile, but that doesn't seem possible under x86_64 (no 32bit targets)? Help!

I'm not too experienced in this, but I suspect a good first step would be to ask for a backtrace (bt) in gdb, after the segfault occured. You'll see the steps that led to the actual segfault, starting from the main program till the library function that failed. Don't immediately suspect the library - go back to the last line of your program and check if all things are normal at _that_ point. AFAIK, core dumps are not really related with gdb, but are generated by the kernel, and should be the last step to fall back on. A backtrace in gdb is generally more helpful.

Hmm, this reveals the question what are the timeouts for TCP/IP connection and for the web services? I think a few seconds are possible, a timeout is usually longer than that. The webservices do not specify any values for timeouts. I'm not sure whether the HTTP protocol has such definitions, but I would be surprised if it had. If using the HTTP protocol, it's possible to define a refresh time of x seconds using a meta-tag: META HTTP-EQUIV=refresh CONTENT=3;URL='http://www.homepage.com/spot3.html' This is quite popular with webcams and such. But this is of course not the definition of a timeout value, you would have to know when the next value is due.

A hand optimized Pascal based solution with goto statements might be preferable over assembler code.

How do I know that a goto is really translated as a jump? I'm no expert, I did see that in many cases ifs, cases, whiles etc, are sufficiently 'recoded' by the compiler such as to make it difficult to garantee that (or know if) the goto is reached fast enough to matter. 2) Compiler semantic analysis is evolving (I imagine), so I'd suspect that optimising is also improving continuously... 3) I also believe that gotos are somewhat like guns. If they're available, it's more probable that people shoot themselves in the foot (or worse). Mind, I don't want to remove gotos. I'm all for free choice.

[fpc-pascal] Redirect under Linux
Hi all... I was testing a program I wrote in FPC which directs the cursors (using crt), by redirecting the output to a file, but was surprised that the escape sequences weren't in the file. Checking the source of the crt units, I found that when redirecting, the sequences are switched off. Is there motive for this behaviour? I just tested the same program under TP7, and, when using crt, redirection isn't possible at all - which is quite logical. Under linux, non-pascal programs do not distinguish between being redirected or not (also logical). I couldn't find a simple way to disable this (short of modifying the crt.pp source code and recompiling)... I need the output of the program to have the escape sequences, as I'd like to use them to feed a terminal emulator program. BTW - beautiful new website!

[fpc-pascal] aterm won't run fp
Hi all Even though I don't have a solution to the previous problem, I already have another one. A while ago I tried 'fp' and didn't get anything. Not having time, I dropped the issue. Now I tried again, and decided to dig a little deeper: 1) in an 'aterm', calling fp doesn't show _anything_, just waits for Ctrl-C to exit to the promps (no menu, no gibberish.) 2) in a real 'xterm', fp works normally - I don't like xterms, because I had some problems with multiple charsets and I haven't found out to make them transparent. 3) I tried with 'aterm --font vga', then start fp - exactly the same. The font changed to vga though, but no fp in sight. Tried several other fonts, switched off 'aterm' transparence, just in case. 4) Also tried to add -tn linux, though that's the default.

[fpc-pascal] eof strangeness
Hi all.
While modifying some older programs, I found a strange effect with eof
(input). When calling eof(input), the program needs an enter key to
continue. I just downloaded 2.0.2, with the same result.
The definition of eof (according to the FPC docs) is that it immediately
returns... which is what I need. Can anyone suggest a solution for this?
program testeof;
begin
if eof then
writeln('EOF found')
else
writeln('No EOF found');
end.
This sample program doesn't return till enter is pressed.
TIA,

[fpc-pascal] Type confusion in GDB?
Hi all.
I was debugging a program and found that the contents of an 'array of
integer' was shown wrong... It took me quite a while to realize that GDB
was showing 32-bit integers, while the pascal program was using 16-bit
ones (at least think is happening):
Assign 1 to firstcol[0]:
(gdb) print firstcol
$27 = {1, 0 repeats 19 times}
Assign 81 to firstcol[1]:
(gdb) print firstcol
$28 = {5308417, 0, 0, 0, 0, 0, 0, 0, 0, 0, 80, 0, 0, 0, 0, 0, 0, 0, 0, 0}
(NOTE that here the 80 actually belongs to another variable (lastcol)).
Printing the array in hex gave me the clue:
$30 = {$510001, $0, $0, $0, $0, $0, $0, $0, $0, $0, $50, $0, $0, $0, $0,
$0, $0, $0, $0, $0}
The $51 is actually the 81...
I think the confusion comes from the fact that firstcol is defined as:
firstcol: array[1..nspecmax] of 1..ncolmax;
which is a range type, not recognized by GDB, and which is 16 bit (in
this case, could probably be even 8 bit).
This problem is not mentioned in the 'Caveats'...
Hope this is of some help.

(This is quite probable, it comes with most distributions) Try: locate libcurses or check in /usr/lib, /usr/local/lib for that lib. if no luck, install it. 2) It's also possible you don't have the library in the search path, John ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

The library was in /usr/lib but I guess FPC is looking for 'libgpm.so' rather than 'libgpm.so.1' .. it's the '.1' that fools FPC and it's happened before. I don't know if it's a RedHat thing .. because /usr/lib/libgpm.so.1 is, itself, a sim link to something like /usr/lib/libgpm.so.1.18.1.. I gather that's the way that one reconciles having the version number in the shared library while trying to let linkers find the libraries... I just wonder why FPC doesn't understand... Maybe this is considered such a trivial matter to people that can write compilers :) Or maybe this is an incompatibility between Linux distro's and RH just loses? If I'm not terribly mistaken, executing ldconfig should generate those links automatically. libgpm.so.1 should automatically generate a libgpm.so if you run it (and you should after installing a new library). That is, of course if /etc/ld.so.conf contains the directory where libgpm is installed. an't help you there. I've had other programs mis-behave... The command history bits of my favorite text adventure game works fine in console mode but screws things up when I'm in Konsole. I spent a little while goggling around about keyboards and character sets and X ... but X is probably the area of Linux that I know the least and I didn't understand any of the stuff I found. As I said - I can't help you there. I've suffered to get fonts working like I wanted under X. I had quite a few problems getting 'composing' working on the keyboard (te get accented characters). The only thing I can recommend is to read the Keyboard-and-Console-HOWTO which is probably installed somewhere on your machine and is quite extensive. I have seen that Xterm has its own ways with many things, which could cause your differences. Almost any other program will act in a more standard way.

Initially, I couldn't link on my old RH 7.2 machine because FPC 1.9.4 couldn't find the GPM libraries. This is probably a stupid question but is there a way that FPC can find libraries better so that I don't have to ln -s /usr/libgpm.so.1 to /usr/libgpm.so? This has happened with other FPC units... Hi Alan. Surely someone with more experience will correct me. But for starters: libgpm.so.1 shouldn't be in /usr - it should be either in usr/lib or usr/local/lib. In that case, your machine will automatically do the link, when it executes ldconfig. Anyway, isn't GPM a mouse package?!? I didn't consult the unit's source but I don't see any mouse functionality in the docs? Just curious. GPM is a combination of both - it permits using the mouse to 'paint' parts of text screens and past them as if someone is typing - so it does have something to mouse _and_ keyboard. And finally, I pasted my little example program below. When I run it in Konsole and it has some funny behavior. Like Shift-F2 is reported as F4 and Control-U is reported as 'SHIFT' ^A and ^E don't seem to have any text associated with them (maybe it's reporting a space?). I wanted to build a simple bash-like command history/editing and I was going to use those but if I cannot read them... Can't help you there. John In xterm it's slightly different... for example, ^A does nothing but then the next charcter shows as SHIFT x (e.g., ^Aa shows as 'SHIFT a') and Shift-F2 shows three keys.. 'Key with scancode 6144', 2, and Q while Shift-F3 shows the same scancode and then 2,R. I tried adding the shift state but that didn't change anything and the shift states don't seem to be read accuractely (control and alt are never read). Thanks! -Alan program readline; uses keyboard; procedure ReadKBD(var S: String); var K : TkeyEvent; begin InitKeyboard; Repeat K:=GetKeyEvent; K:=TranslateKeyEvent(K); writeln(KeyEventToString(K)); Until (GetKeyEventChar(K)='q'); DoneKeyboard; end; var S:String; begin ReadKBD(S); end. -Alan ___ fpc-pascal maillist - [EMAIL PROTECTED] http://lists.freepascal.org/mailman/listinfo/fpc-pascal ___ fpc-pascal maillist - [EMAIL PROTECTED] http://lists.freepascal.org/mailman/listinfo/fpc-pascal

I don't know if there is a more elegant solution, apart from trying to open a new window with a gnome-canvas in it or so. The best solution would be an SDL-based graph unit, I think. Nobody's working on that though, afaik. Jonas Hi Jonas. I did a 'client-server' type of thing. On the Pascal-side it looks like a Graph-compatible library. But instead of switching modes, it starts a new window, with a gnome-canvas in it. The 'graph' lib then sends its graphic commands through a pipe to the new window. It is far from usable (many things are missing) but the idea has several pluses (in my opinion): 1) The 'remote graph' can be called from other programs as the interface is just the pipe. I could even be called from bash... (never tried) 2) The gnome canvas has nice anti-aliased graphics, and the resulting plots _do_ look very nice. As I said, it is far from complete (eg. no fonts yet) and not very stable either. One thing I haven't found yet is a way to save the gnome-canvas to a graphics file (I just made screen shots). With the experience I had later with gnome-print library, I could image that this could also be combined somehow. Is there interest in this?

[fpc-pascal]CR / CRLF problem when redirecting to file
Hello all,
In Linux, when redirecting FPC output to a file, I found that after 25
lines, CR characters are being added, as if in DOS:
program TestCR;
uses
CRT;
var
i: integer;
begin
for i := 1 to 50 do
writeln('The quick brown fox jumps over the lazy dog''s back ', i);
end.
when doing a ./testcr testcr.txt
CR's appear on line 25 and after. (This seems to profoundly confuse some
terminal windows, which change mode and have to be 'reset').
John

I didn't have crt in my program, but called another unit that did have it. So the danger is always present ;-) Reassigning assign(f, ''); works for directing to a file, but the output on the screen doesn't work. Will have a look at nCRT...
