fatal error: QColor: No such file or directory

SPlatten

@jsulm , I've done:

make clean
make depend
make

Still getting the same error. I don't know where the build folder is, any suggestion on how to locate it?

[Edit] found the build folder it was hidden.

jsulm

@SPlatten You forgot qmake.
And as I wrote: delete build folder or its content including hidden files, run qmake then make...

SPlatten

@jsulm , qmake results in:

-bash: qmake: command not found

I can run qmake-qt5.

Then do so, or use absolute path to qmake you want to use...

I have added a header to the project that starts off with:

./../include/ASVscm/services/vehicle/dataMgmt.H:13:10: fatal error: QColor: No such file or directory

And is that the file into which you have added your #include <QColor>? Since you do not say we do not know....

Start by putting a #include <QColor> directly into one of your local .cpp or .h files in the current folder and trying to compile (without that bad .h file). Does that work or error? Then we know whether it is somehow to do with the dataMgmt.H file or not....

@SPlatten
And what have you done about the suggestion?

@JonB , same result:

client.C:11:10: fatal error: QColor: No such file or directory
 #include <QColor>
          ^~~~~~~~
compilation terminate

@SPlatten
So maybe you do not have the necessary files in the Qt installation area, or it's using a different Qt installation area from what you think it should....

Try different #include <...> statements using something else than QColor. Is it QColor only, or are others not found?
Create a brand new, standalone, tiny project, not the whole project you are using now. Does it work or fail there?

@SPlatten How did you install Qt and are you sure you use Qt version you want to?

SPlatten

@JonB , the structure of this project contains many sub-projects each with they're own .pro files. I've search all the projects for the same inclusion:

grep -Rnw ./ -e "#include <QColor>"

And I have found other instances, then checked the .pro content for these and they don't appear to be any different.

I know this isn't logical, if I go to the local directory containing the .pro for the project I'm having difficulty with and execute:

make clean
make depend
make

It builds with no errors, its the same process from the parent that is when I get the error.

SPlatten

@jsulm , unfortunately thats completely out of my control, the laptop I'm using is supplied by my client, installed with RedHat 7.2 and Qt, the version of Qt is specific to the project.

Please explain things clearly! "don't appear to be any different." might mean they have the same line and they (a) do work without the error or (b) do not work and show the same error .....

Anyway, I can only suggest you discover the exact compilation command-line being used. #include <...> should only look in system directories. Are these somehow different for the faulting case, that is all I can think of.

SPlatten

@JonB , I used grep to find the same include in other projects that do compile without error:

grep -Rnw ./ -e "#include <QColor>"

I then looked at the .pro file. I cannot see anything that I have done differently.

kkoehne

Can you show the full command line for the compiler call that fails?

@SPlatten said in fatal error: QColor: No such file or directory:

-I/usr/include/qt5 -I/usr/include/qt5/QtNetwork -I/usr/include/qt5/QtCore

Are these the directories where Qt's include files including for QColor are located?
How does this command line compare against one issued for a file which does find <QColor>?
