Thanks Vincent,
I did not think of it as there are only about 30lines of output. It
works now.

The following piece of code is giving me headaches. When I add the
option poUsePipes, the application starts and does not seem to do
anything else anymore. It just opens a commandline terminal and that
is that. When I leave the option out the application actually starts
"make" and then crashes because AProcess.Output is nil.
What did I forget? I'm working on WinXP. On Linux btw the code works.
Darius
procedure ExecuteApp(CmdLine: string);
var
AProcess: TProcess;
AStringList: TStringList;
begin
AProcess := TProcess.Create(nil);
AStringList := TStringList.Create;
AProcess.CommandLine := CmdLine;
AProcess.Options := AProcess.Options + [poWaitOnExit, poUsePipes];
AProcess.Execute;
AStringList.LoadFromStream(AProcess.Output);
AStringList.SaveToFile('output.txt');
AStringList.Free;
AProcess.Free;
end;
begin
ExecuteApp('make');
end.
Maybe the output buffer is full and the application is waiting for you
to read from the pipe. See the reading large output program at
