Debugging two processes with Qt Creator?

[SPlatten]

I'm working on my iMAC with Qt Creator. I have a process that I'm debugging, I have another process that I also want to debug at the same time.

Is it possible to launch another instance of Qt Creator so I can debug both processes at the same time?

Why not simply try it out?

[SPlatten]

@Christian-Ehrlicher , I have and thats why I'm debugging it, because it doesn't currently work.

because it doesn't currently work.

This is no real problem description.

[SPlatten]

@Christian-Ehrlicher , there is no description because I don't know why it doesn't work, if I new what it doesn't work obviously I could fix it, this is why I want to debug it so I can investigate further.

[Christian Ehrlicher]

Sorry I don't understand your problem - "It does not work" does not help. What exactly does not work? Can't you start two instances of QtCreator? Can't you start the second debugging session in the second QtCreator?

[SPlatten]

@Christian-Ehrlicher , where exactly did I use your quote "It does not work" ?

I said I want to debug two processes using Qt Creator, I want to launch two separate instances of Qt Creator, the first debugging one process and the second debugging another. I then want to debug the interaction between both processes.

The problem I have is that I do not know how to start two instances of Qt Creator, how much clearer can I be?

You never said this before...
Don't know why you can't start two instances on MacOS. It works fine on Windows and Linux.

[SPlatten]

@Christian-Ehrlicher , in my original post I said "Is it possible to launch another instance of Qt Creator", another meaning in addition to the first instance...

[Christian Ehrlicher]

@SPlatten No, there you ask if it is possible, not that it does not work for you - these are two different things.

[SPlatten]

@Christian-Ehrlicher, again, isn't it obvious that before coming on here and posting the question I would have tried it?

@SPlatten
I know nothing about Mac. But I assume you launch these Creators by clicking on an icon? And maybe that is what checks for/prevents multiple separate occurrences? Assuming it's like Linux, can you open a shell and type in the command-line to run Creator from there? In which case, does that allow multiple instances?

No.

[SPlatten]

@JonB , whats the command to launch Qt Creator from a terminal ? On Windows I can just right click the icon and get the info from there, on a Mac it's not so simple.

@SPlatten

On windows I can start qt creator by calling <proper path>/qtcreator from command prompt. Do not know on mac

[SPlatten]

@JonB , @Christian-Ehrlicher, @koahnig

Ok, I opened the contents of the folder "Qt Creator.app" then went to Contents/MacOS and launched "Qt Creator", now I have two instances of Qt Creator open I will see if I can debug two applications simultaneously.

Well that's the $64K question! Can't you find where an executable qtcreator is on your disk (Mac Finder?) and type in the full path to that? I would have thought it would be worthwhile to discover where exactly all the Qt stuff is installed on your disk once & for all, you might want to look inside header files etc.
