[SOLVED] .pro-Files without HEADERS

[Asperamanca]

I was asked why we need to include the HEADERS into our .pro files. I should note that we do not use Creator as our primary IDE, we create the .pro-Files in order to use qmake for batch compilation.

Is there any good reason other than the IDE to include the HEADERS? Will omitting them cause dependency problems? Would a .pro-File without HEADERS still open & compile in Creator (for those of us who occasionally use that IDE)?

Hi,

According to the "doc":http://doc.qt.digia.com/4.7/qmake-variable-reference.html#headers, the HEADERS variable is used by qmake to generate dependency information and detect if moc is required. So, yes, there are good reasons ;)

[Asperamanca]

But shouldn't adding a DEPENDSPATH to the path where the headers are located do the same thing?

[SGaist]

No, this tells qmake to check wether something has changed in these paths and rebuild if necessary

[Asperamanca]

If I understand you correctly, moc might not be run based on a header file change, even if the folder containing the header file is part of the DEPENDS_PATH.
Right?

[SGaist]

Yes, qmake will take the files from HEADERS and parse them to know if moc needs to be run.

Thanks!

(Note: Seems like a plain "Thanks" does not conform to some posting rule. So I add this rather pointless explanation)

You're welcome !
