[lazarus] Console app problems
Hi all,
I'm try to write a console application that interfaces with Asterisk
PBX. The pbx communicates with the console application over stndin and
stdout.
The problem that I'm having is that when I send a command using WriteLn,
the command doesn't return as it should so I'm wonder if FP/Laz handles
stdin/stdout in some way that I am not familiar with.
Is the data written to WriteLn buffered or sent immediately? Below is a
sample of the code I am trying.
// Asterisk sends environmental vars at the start of the app
// over stdin. When it's finished it sends a blank line.
Repeat;
begin
ReadLn(sRead);
if (pos('uniqueid', sRead) 0) then
sUniqueID := sRead;
end;
until (sRead = '');
// -//
// Parameters Passed to app from Asterisk
// -//
// 1=DataToPlay, 2 = VoiceToUse
sData := paramstr(1);
sVoice := ParamStr(2);
// which voice to use? If none specified use the default
if (FileExists(sData)) then
begin
// assume it's path to a text file. Build Cmd line accordingly.
sCmd := sExePath + '/swift -f ' + sData + ' -o /tmp/' + sUniqueID +
'.wav';
sCmd := sCmd + '-p ' + sParams;
end
else
begin
// assume that we are synthesizing the actual text provided in
parameter to app
sCmd := sExePath + '/swift -o /tmp/' + sUniqueID + '.wav';
sCmd := sCmd + ' -p ' + sParams + ' '+ sData + '';
end;
Proc := TProcess.create(nil);
try
// Send command and write to file
Proc.CommandLine := sCmd;
Proc.Options := Proc.Options + [poWaitOnExit];
Proc.Execute;
// Write out command to play file to Asterisk over stdout
WriteLn('PLAYBACK /tmp/' + sUnique);
ReadLn(sCmd); // = Gets stuck here. Does not return.
// finally, delete the file
Proc.Active := false;
Proc.CommandLine := 'rm -f /tmp/' + agi.UniqueID + '.wav';
Proc.Execute;
finally;
Proc.free;
end;
Thanks,

The pbx communicates with the console application over stndin and stdout. Sorry for the question, but are you on the right library to use AGI ? Sorry, I'm not sure I understand your question. If you mean, am I writing to the correct list, then yes. I just want to be sure that I understand the mechanics of stdin/stdout within a console app. I've only written GUI apps mostly. If you mean, am I using the right comiler/tool, then yes. Asterisk communicates with any program over stdin/stdout from what I understand and reading the asterisk wiki. I've actually written a couple of AGI programs in C#/Mono, but didn't like the extra setup required for the mono runtime. The problem that I'm having is that when I send a command using WriteLn, the command doesn't return as it should so I'm wonder if FP/Laz handles stdin/stdout in some way that I am not familiar with. As far as I know (I will know more in this week btw :)), you should also check STDERR. I will. Is the data written to WriteLn buffered or sent immediately? Below is a sample of the code I am trying. It always buffered. Please take a look at http://www.freepascal.org/docs-html/rtl/system/settextbuf.html It also appears that a standard Writeln automatically issues a flush() command anyway: http://www.freepascal.org/docs-html/rtl/system/flush.html Ido Thanks for responding. It appears the problem may very well be between the back of my chair and the keyboard. I will start again with a very basic program and work myself up from there to find out where I am going wrong. -- Warm Regards, Lee _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

First, I have fixed it (or worked around) and will share my finding on a separated post to this thread. Do you mean where the file is located on the linux box? It's in /var/lib/asterisk/agi-bin. As I mentioned, I actually wrote a couple agi's using Mono and C#, but didn't like having to setup mono and then you had to associate exe files with binfmt and such, it was not something I wanted. I use delphi a lot in windows and I love the pascal language so much, easy like vb, but strong like C! So you can see my motive in getting things to work with fp/laz. Good luck, and if you can please share your sources :) Indeed. I have actually ported the MONOTONE.cs class written by Gabriel Gunderson (link below) to a pascal object class. I was just starting to test it for bugs when I got bogged down with my current problem. http://gundy.org/asterisk/MONO-TONE-0.02.cs.txt -- Warm Regards, Lee _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

Hi all, after trying a number of different ways to get this to work, I
have found a way.
For some reason, it does not appear to me that using standard Writeln()
to send commands to Asterisk are ignored for some reason, even when
appending #10 or #13#10 or #13 to the end.
At any rate, following the example here:
http://www.freepascal.org/docs-html/rtl/system/flush.html
I create explicit file associate with stdout:
var
F: Text;
sRead, sRet: string;
begin
repeat;
begin
Readln(sRead);
// other assign values as needed
end;
until (sRead = '');
Assign(F,'');
Rewrite(F);
Write('NOOP Here is some sample output to CLI' + #10);
Flush(F);
ReadLn(sRet);
Close(f);
end;
One thing that I ran across was that if I also tried to ReadLn using the
explicit F file, I got an AV.
So it seems (at least for me and my particular setup) that ReadLn reads
ok with Asterisk, but an explicit control over stdout must be used with
explicit flush()'s to ensure that Asterisk gets the ouputted command.
Keep in mind that I am not debugging my app in real time. I'm compiling
it on a VMWare linux image on my windows box and then copying it over to
my asterisk linux box. Just been using a lot of file logging to see
what's going on under the hood when the app runs.

Naturally it's a matter of taste, but I really cannot get used to the
indenting of begin-end. It just looks wierd to me, even after all these

It's something like
for (int x = 0; x 99; x++)

[lazarus] Rebuilding IDE with sqlite3 support

I tried installing from source originally, but had a mess of problems with the IDE not finding any packages, etc so I settled on installing from RPM. Do I have to install from source to rebuild?

Oh, and I forgot, thanks to everyone for their time and patience ;)
I'm just a bit frustrated right now, lol.
Hi,
You might want to try finding all instances of lazarus executable
in your entire system with a file manager started as root, by
searching from '/' directory with 'include subfolder' options.
Try them one by one and maybe you might find one that has the
components that you installed.
If you do find it, you'll at least know where your compiled
lazarus executable went. If not, then its a bizarre bug.
(I have all SQLDB components on my component palette.)
Another option is to specify where you want your compiled
lazarus executable to end up by specifying a target directory
in Tools-Configure Build Lazarus, and rebuild lazarus.
I did a search as root and I didn't see multiple instances of lazarus,
except for what I think were symlinks and I had a bit of trouble getting
rid of them. Had to actually click on them and let the os decide they
were no longer valid and I chose to remove them when asked.
I tried then rebuilding laz with uib, but then when trying to restart
lazarus, I got the error about trying to start threads before they are
initialized. I've seen this before when I was writing my first app
with laz, a tcp server.
My guess is that its a problem with one or more units in UIB without an
{IFDEF} around a ctthreads inclusion. I will try and download UIB
latest version (6?) and try that.
Meanwhile, I'm reinstalling laz from source again, LOL.

Woohoo! That worked.
I think changing the build path did it, although I'm not sure. I set
the build path and then went immediately about trying to install the UIB
components when I received the cthreads error when trying to start
lazarus after a rebuild.
Inside lazarus.pas is this definition in uses clause:
{$IFDEF UNIX}{$IFDEF UseCThreads}
cthreads,
{$ENDIF}{$ENDIF}
I haven't play much with include files, even with delphi other than to
change some compile settings for rxlib or such. I'm assuming there is
an include file in there somewhere where I can define specifically to
use cthreads unit.
To test, I just removed the inner UseCThreads $IFDEF and I compiled
and with jvUIB components on the palette!
Anyone know which file that is defined in or what a better way of
switching this would be? I hate to change the lazarus.pp file permanently.

[lazarus] Compiled Linuxy Binary Compatibility/A bit (OT)
Hi all, I have a question about binary compatibility for linux programs that I write in Lazarus/Freepascal. I've done some googling, but am still unsure as to the answer to my question. Namely, if I do not provide source to a program, but still want to distribute it, can I compile the binary on a specific platform and run it on another without re-compiling? For instance, can I compile on a i686 box and run the binary on a 586 box as it is, compiled for 32bit? Or can I 32 bit binary run on a 64 bit linux? Sorry, I know it's a bit OT.

This particular piece of software is a simple xml based TCP server written in Laz/FP for a Windows client software so I have no problem with providing the source. Personally, I just don't think it would be very convenient to customers to have to download the FP compiler and compile the software. Maybe binaries by default with access to the source if they want it...this way a large majority of linux users could use the binary as is, but users with less prevelant distros would still be ok, if a little more inconvienced. -- Warm Regards, Lee _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

Before diving into the rpm building trouble, I first try to figure out, how I could install a package into lazarus without using the ide. With lazbuild, I can compile the package, which is fine. But how can I recompile lazarus to include the package? Do I have to deal with idemake.cfg and staticpackages.inc manually? For my special needs, I could of course create the correct files and do a make ide -w OPT=@/etc/lazarus/idemake.cfg but a commandline tool (or switch for lazbuild), that enables installation/uninstallation of packages would be really helpfull. So the question: Is there allready some (hidden) feature to do this? No, there is none yet. You have to fiddle with idemake.cfg and staticpackages.inc (easy for one package, but not flexible) or extend lazbuild (difficult, but flexible). I'd like to test the easy way first, but there are problems with staticpackages, even when not fiddling with it: Fist goal is to re-compile lazarus having previously installed packages included. Situation: (i386-linux, suse 10.0 / own linuxfromscratch with rpms) * fpc is installed globally (/usr/local/) incl. indy-fpc * lazarus installed in home (~/FreePascal/lazarus) * indy is in home (~/FreePascal/indy/lazarus) * glscene in home (~/FreePascal/gscene) * lazarus is running with bigide, indy and glscene installed. All components on the palette. Now when I remove the lazarus folder, get a fresh svn co, do a make clean all bigide, bigide ignores user settings and compiles a static set of packages. 'make idepkg' compiles with user settings. start lazarus, it does not show my previously installed packages. I have to open one of the packages (doesn't matter if indy or glscene) and click install. Now it compiles all the packages and on restart everything is fine. This is 'make idepkg'. Yea, that works, if all packages have been compiled before. So for the records: in a clean lazarus checkout, doing * make all bigide * ./lazbuild -B ../indy/lazarus/indylaz.lpk * ./lazbuild -B ../glscene/LazarusLin/glscenelazarus.lpk * make idepkg gives me a fresh ide containig all my previously installed packages. Very nice, thanks.

I just knew that someday there will be more and more Delphi component
providers support FPC/Lazarus due to active development of FPC/Lazarus
and lack of Borland/CG interest to non-Windows platform. And someday,
Borland/CG will have no options except support FPC/Lazarus because
they'll be far behind FPC/Lazarus for non-Windows platform.
FPC as a compiler is a mature and stable product. Morfik and Pixel
obviously shows its power. What I've been waiting to jump to FPC vehicle
is AtoZed's Intraweb. :-D From Borland/CG, I'm thinking that someday
they will offer Delphi for Pascal IDE with FPC as an alternative
compiler to compete with (or terminate) unofficial CrossFPC. ;)
-Bee-
Is CrossFPC still being developed? I had read somewhere that it was
stalled again.
Personally, I've come to like Lazarus quite a bit and am very
appreciative of the Laz's developers efforts. Of course, I'm still
using D6 on windows and Laz is pretty comparable.
If only there was a way to better promote Lazarus/FPC. Recently, I've
been doing quite a bit of development on Linux and I swear, I get a lot
of Pascal? That's still in use? or I remember that from high
school! or Yes, that was used back when the world was flat.
OP needs a major marketing overhaul IMO.
Here is my pitch: Object Pascal. Strong Like C. Easy like VB. ;)

No doubt there is a learning curve. The tiOPF framework is big, but it's no different compared to someone that's new to the LCL or VCL. It take a while to get to know the things you are going to need first and then keep learning new features as you get more familiar with the framework. I'm currently bringing the documentation up to date. All the docs where written for tiOPF ver.1. A few things have changed in tiOPF ver.2, but for the better. Easier unit and class names, lots of code cleanup, etc. but the basic functionality is still the same. To work with the framework, I would say you have to work through the Concept Documentation - Chapters 1, 2 and 3 and actually write the code examples. This will lay the groundwork of how the framework was built and how the Visitor pattern is used. The Visitor pattern is the hart of the framework.

[lazarus] Linux/Printing Question
Hi all, This is quite a bit OT since the only thing related to Lazarus is that I will use to write the software. One of my company's main products does a lot of prep notifications to various printers on the network. For a single order (sale), prep instructions can be sent to up to 6 different printers. One of the things that has always been a problem with doing this kind of critical printing in windows has been the lack of status or way of querying printers (many are on print servers). I remember there was a way to send a fake print job and monitor using the Win32 API, but I had difficulty getting reliable printer status and it doesn't seem to work very well. Is this kind of printer monitoring possible in Linux? We are thinking about putting together a kind of Linux Appliance to do this and move the printing portion away from Windows, assuming printer status is obtainable on Linux like outlined above. Thanks for input. -- Warm Regards, Lee _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
Re: [lazarus] report writer 4 Lazarus?
Heine Ferreira wrote: Hi Does Lazarus have a report writer? If not, is there any free or low cost report writer out there that would work with Lazarus? I have tried to post this in the forum, but there was no response. I only know of three report writers that are free. LogiXML - for web based reports. Jasper Reports - for Java. Report Manager - I used it with VB6 and it works with Delphi 5 and upwards. It also works with dot net. I tried it on a couple of reports and found it rather clumsy and buggy. Does anyone know of anything else out there? I am looking for a report writer that would work well on Windows. May be I'm too fussy, but I am used to good report writing tools like Crystal and SQL Server reporting services. Crystal is rather expensive or you must buy Visual Studio and the free version of SQL Server is too limited and too hungry for memory. Thanks Heine Ferreira LazReport is based on freereport, I think. http://lazreport.sourceforge.net/ I believe Freereport was the ancestor of FastReport. Someone can correct me if I'm wrong. -- Warm Regards, Lee _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

I tried this and it didn't work, unfortunately. The odd thing is now my local Firebird server won't run. I get a freepascal runtime error message when I try to run FirebirdSQL !!! Anyone have any idea what would cause that? Not sure if its related or not, but didn't manifest itself until after I was playing with lazarus and file output path. I uninstalled FPC/Lazarus to see that would fix it, but no luck. -- Warm Regards, Lee _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
