Qt Creator Not Recognizing my own header file.

[Plissken]

Yes, those are there but still not recognizing them:

INCLUDEPATH += $$PWD
DEPENDPATH += $$PWD

Edit: Odd. I've removed the files and even added (existing) files, so that the .pri file does its auto stuff, it still doesn't recognize only that file (I have other files that are recognized fine).

How are you including the file in your sourcecode?

[Plissken]

#include "internal_lib/widgets/sheet_wp.h"

[wysota]

How about this:

INCLUDEPATH += internal_lib/widgets

INCLUDEPATH += internal_lib/widgets

To copy to clipboard, switch view to plain text mode 

and then:

#include "sheet_wp.h"

#include "sheet_wp.h"

To copy to clipboard, switch view to plain text mode 

Does it change anything?

[Plissken]

No, it doesn't. Same error message. This project folder I had cloned from a git repository. I wonder if that has anything to do with it? When I open the .pro file for the first time, it asked whether I wanted to load the .user setting files (but it recommends that I don't) so I just clicked no.

The weird thing is that the code compiles fine on the computer that this project was originally created on.

Can we see the actual compiler invokation that fails?

[Plissken]

error: C1083: Cannot open include file: 'internal_lib/widgets/sheet_wp.h': No such file or directory

compiler command, not error

[Plissken]

I got this working. I don't know the exactly why it got it working, but I was reading the definition of PWD in the Qt Docs and a word that caught my eye in the definition was shadow build. I realized in the original project which did compile correctly was using shadow building, but the same project I loaded on a different computer was not using shadow building. Once I enabled shadow building (and this must be done when the pro file is loaded for the first time, not later on) it started compiling without errors. Thanks wysotta for your help.
