Subject: [fpc-pascal] including libraies ?
I tried to write a little utility to submit a command to the At Facility.
The code to do this is as follows:
program TestPrg;
Uses Classes, Process;
Var
i: Integer;
Cmd, Pre, Post, StrVar, SwStr: String;
MyProcess: TProcess;
SOut, EOut, StdStrLst: TStringList;
Begin
StdStrLst := TStringlist.Create;
SOut := TStringlist.Create;
EOut := TStringlist.Create; EOut := TStringlist.Create; MyProcess :=
TProcess.Create(nil); MyProcess.CommandLine := 'at now';
MyProcess.Options := MyProcess.Options + [poUsePipes]; MyProcess.Execute;
StdStrLst.Clear;
StdStrLst.Add('awk -F":" ''{print $1"\t"$3"\t"$4}'' /etc/passwd |
sort'); StdStrLst.SaveToStream(MyProcess.Input); StdStrLst.Clear;
StdStrLst.Add(chr(4));
StdStrLst.SaveToStream(MyProcess.Input);
SOut.LoadFromStream(MyProcess.Output);
For i:=1 to SOut.Count Do
WriteLn(SOut.Strings[i]);
EOut.LoadFromStream(MyProcess.StdErr);
For i:=1 to EOut.Count Do
WriteLn(EOut.Strings[i]);
End.
Running this code from a Lazarus test program works with out any problems.
When running it from a Free Pascal (non gui,) the program finishes
normally, but nothing gets submitted to the AT Facility.
uses Classes, SysUtils, FileUtil, LResources, Forms, Controls, Graphics,
Dialogs,
StdCtrls, Process;
Someone on the Lazarus List recommend I add SysUtils to my utility
program. I am not sure how to do this. SysUtils has many included files
in there and they are all in other directories, none of which are in my
path. I am sure there is some simple method here that I am totally
ignorant of.
HI Terry, you should be able to just include SysUtils in your uses clause
without any issues.
The compiler should be able to find that unit (and others needed)
automatically...
{code}
Uses Classes, Process,SysUtils;
{code}
cheers,
Paul
