Communicating with stdout and stderr

OK hi I've got a question. I start a process with:

Source code

 
1

makeProc->start (KProcess::NotifyOnExit,KProcess::Stdout);


and make connection with:

Source code

 
1

connect( instProc, SIGNAL( receivedStdout (KProcess * , char *, int) ), this, SLOT( getText(KProcess*, char*, int ) ) );


and

Source code

 
1

  connect( instProc, SIGNAL( receivedStderr (KProcess * , char *, int) ), this, SLOT( getErrText(KProcess*, char*, int ) ) );


Ok my question: I know that only the first connection works, but how can I start a Kprocess with stdout and stderr?

You have to OR the proper communication flags

Source code

 
1

process->start(KProcess::NotifyOnExit, KProcess::Stdout | KProcess::Stderr);

It doesn't work, I get this error:

Source code

 
1
2

/comain/src/workform.cpp:127: error: invalid conversion from `int' to `KProcess::Communication'
/comain/src/workform.cpp:127: error: initializing argument 2 of `virtual bool KProcess::start(KProcess::RunMode, KProcess::Communication)'


what's the problem?

Argh, sorry!

Use KProcess::AllOutput as the communication mode.
