Problem compiling qt5-related software

[jlindgren]

Hello!!

I am sure this have came up earlier but I have yet to find a resolution for it.

I have come across a problem to upgrade my gentoo system because of this; I dont think this is gentoo-specific, since very similar errors occur on many systems aparrently, however the difference is the paths in quotation-marks after:"The imported target "Qt5::Core" references the file" differ only for which I can see.

I have heard that double-slashes is not the issue, however there is something missing and I don't know what.
For sure I can submit the whole log, however I thought that perhaps someone recognises this very problem :)
I just don't understand what it's looking fore here:

CMake Error at /usr/lib64/cmake/Qt5Core/Qt5CoreConfig.cmake:27 (message):
The imported target "Qt5::Core" references the file

"/usr/lib64/qt5//mkspecs//usr/lib64/qt5/mkspecs/linux-g++"

but this file does not exist. Possible reasons include:

* The file was deleted, renamed, or moved to another location.

* An install or uninstall procedure did not complete successfully.

* The installation package was faulty and contained

"/usr/lib64/cmake/Qt5Core/Qt5CoreConfigExtras.cmake"

but not all the files it references.

[d_stranz]

Seems like line 15 is garbled - it contains the first part of the path twice. Look at line 27 of your file Qt5CoreConfig.cmake to see if there is an indication of what might cause the error.

Is this error occurring in a CMake generate step, or later?

[jlindgren]

Yes, the line 27 only indicates the case of a FATAL ERROR in case the ${file} does not fulfil, and I don't understand what file that is, in case that is the actual problem?

[d_stranz]

I think you need to post the CMakelists.txt for the top level project, as well as the command line you are running when this error occurs. It looks to me like an environment or CMake variable that tells it where to look for Qt components is set incorrectly.

And the rest which made the last post to long :-)

Compillation; one of several packages to be compiled for qt5 support which ends up in the same way.

Change the environment variable "QMAKESPEC" to simply "linux-g++" (without the " marks, of course).

[jlindgren]

I have tried changing that variable before but it didn't really get set, as the variable error is still exactly the same...



#env|grep -i qmake
QMAKESPEC=linux-g++
#rm -r /var/tmp/portage
#emerge -v cmake


The change was nothing :confused:
Error still points to "/usr/lib64/qt5//mkspecs//usr/lib64/qt5/mkspecs/linux-g++"

Am I missing something?

[d_stranz]

I understand now - you are trying to build CMake itself (or at least the GUI driver for it). I think you look on Kitware's forum for an answer, and if you don't find one, ask there. It is likely someone there will know the answer.

[jlindgren]

No, this error occurs on several packages, but cmake was only one of those I tried to upgrade. Another I tried was phonon, with that same message!

This is when trying to compile phonon. (Qmakespec is still only linux-g++ )

Maybe this will help (https://bugreports.qt.io/browse/QTBUG-61768); see the "simple fix" near the end of the post. Even though the original post concerns a Window Qt installation, the error is exactly the same as you are having, so the fix should work for you also.

Fantastic thank you very much!! :D
It was just as simple fix as I thought it would be, only of course I didn't know how to find it... My only way out would pretty much be to remove /usr and rebuild the system WITHOUT knowing what was causing the error.

According to the bug report, this has been fixed in Qt 5.9.2, so upgrading Qt and rebuilding might be worth it if you want to avoid messing with your Qt files.

I tend to fix a problem, update, then see the same problem again. Meanwhile, I have forgotten what I did to fix it. :p
