In the search results I see a ubuntu package that shows the path
/usr/include/qt5/QtGui/5.2.1/QtGui/private/qicon_p.h

I have /usr/include/qt5/QtGui/
but no /5.6.0 or any other folder…

from the linked issue:

Looking at the make output:
-I/usr/include/qt5/QtGui/5.6.0 -I/usr/include/qt5/QtGui/5.6.0/QtGui
-I/usr/include/qt5/QtCore/5.6.0 -I/usr/include/qt5/QtCore/5.6.0/QtCore -

I have usr/include/qt5/QtCore and /QtGui but they don’t have a 5.6.0 folder in them.

and the reply: “But you should have. That’s something wrong with your Qt deployment.”

Hi
They should use pkgconfig to to check the relevant development pc file for all the libs, flags etc. Sounds like you need to patch the files…

eg /usr/lib64/pkgconfig/Qt5Core.pc;


prefix=/usr
exec_prefix=${prefix}
libdir=${prefix}/lib64
includedir=${prefix}/include/qt5

host_bins=${prefix}/lib64/qt5/bin

You need to install libQt5Gui-private-headers-devel, that contains the private libQt5Gui5 headers (/usr/include/qt5/QtGui/private/qicon_p.h e.g.).

But if the application has the include paths really hardcoded to /usr/include/qt5/xxx/$version/, that won’t help either obviously.

Thanks :-]

Regardless of the aforementioned…
I just ran
find /usr -name *qicon_p.h
but it didn’t find anything.

Ah hello again wolfi… let me try that.

Actually that package produces:
/usr/include/qt5/QtGui/5.6.0/QtGui/private/qicon_p.h

So problem solved :smiley:

Thanks again!

Ah yes.
The private headers actually all install to /usr/include/qt/xxx/$version/, while the public headers are in /usr/include/qt5/xxx/ directly.

I suppose that’s because the private headers are highly specific to the particular Qt version. As they are private (and not supposed to be used by applications), they can radically change from one version to the next (even minor) without notice.
