I've used the following code in fpGUI's demo IDE and it works here under
FreeBSD, Linux and Win2000-Win7 (I don't have Win8 so can't test that).
The following code executes the FPC compiler an captures the results and
triggers an event, which eventually displays the output in a message window.
=============================
procedure TBuilderThread.Execute;
const
BufSize = 1024; //4096;
var
p: TProcess;
c: TfpgString;
unitdir: TfpgString;
Buf: string;
Count: integer;
i: integer;
LineStart: integer;
begin
unitdir := GProject.ProjectDir + GProject.UnitOutputDir;
unitdir := GMacroList.ExpandMacro(unitdir);
if not fpgDirectoryExists(unitdir) then
begin
{$IFDEF DEBUG}
writeln('DEBUG: TBuilderThread.Execute - Creating dir: ' + unitdir);
{$ENDIF}
fpgForceDirectories(unitDir);
end;
p := TProcess.Create(nil);
p.Options := [poUsePipes, poStdErrToOutPut];
p.ShowWindow := swoShowNormal;
p.CurrentDirectory := GProject.ProjectDir;
// build compilation string
c := gINI.ReadString(cEnvironment, 'Compiler', '');
c := c + GProject.GenerateCmdLine(False, BuildMode);
c := GMacroList.ExpandMacro(c);
// AddMessage('Compile command: ' + c);
p.CommandLine := c;
try
p.Execute;
{ Now process the output }
OutputLine:='';
SetLength(Buf,BufSize);
repeat
if (p.Output<>nil) then
begin
Count:=p.Output.Read(Buf[1],Length(Buf));
end
else
Count:=0;
LineStart:=1;
i:=1;
while i<=Count do
begin
if Buf[i] in [#10,#13] then
begin
OutputLine:=OutputLine+Copy(Buf,LineStart,i-LineStart);
Synchronize(@DoOutputLine);
OutputLine:='';
if (i<Count) and (Buf[i+1] in [#10,#13]) and
(Buf[i]<>Buf[i+1]) then
inc(i);
LineStart:=i+1;
end;
inc(i);
end;
OutputLine:=Copy(Buf,LineStart,Count-LineStart+1);
until Count=0;
if OutputLine <> '' then
Synchronize(@DoOutputLine);
p.WaitOnExit;
finally
FreeAndNil(p);
end;
end;
