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?
