The $top_srcdir variable

[Arukas]

Hello-

Can anyone shed some light on the $top_srcdir? I'm using Qt in linux and I can't figure out where this is defined or how to define it. So far everything, I have read is above me.

Thanks,
Arukas

Which build system are you actually using?

[Arukas]

The default one instlalled by Qt.

[tobias.hunger]

The default is qmake.

So where did you see that variable? Where do you want to use it?

[Arukas]

Each part of the project has its own project file, and they have the $top_srcdir pointing to the main project file.

I'd like to set those pointing to where I have my main project.

Did you read the section on variables in "the Qmake manual":http://qt-project.org/doc/qt-4.8/qmake-advanced-usage.html?

[Arukas]

top_srcdir is a preset output variables, so that manual isn't applicable.

Sorry, I do not understand what you want to do. Where did you find top_srcdir to be a preset output variable?
