Performing Test Qt5Gui_PRIVATE_HEADER_FOUND - Failed

[RaymondH]

This is the contents of the file. It is located int the Qt distribution at this location: .../lib/cmake/Qt5Gui.

This is just using the scripts that came with Qt & QtWebKit, I don't believe I'm doing anything unusual or custom.

@RaymondH Could you upload CMakeOutput.log and CMakeError.log?

[Konstantin Tokarev]

And CMakeCache.txt

Sorry, but apparently I don't have permission to attach files, so I just listed it here.

Here is CMakeOutput.log (Part 1):

Looks like a problem with your compiler and/or Qt

[Konstantin Tokarev]

As for error reporting: yes, it's highly misleading, but unfortunately cmake doesn't allow making compilation tests without linking (and this test should check just that #include doesn't fail

[RaymondH]

Ok, thanks. I will investigate.

Thanks so much for taking the time to help.

[Konstantin Tokarev]

By chance, are you using custom mkspec when building Qt? Assuming that Qt is built with the same compiler

[RaymondH]

I have resolved the issue with the undefined references to the three libraries as indicated above.

However, though that was fixed, I now do indeed have an issue with the private headers not found, as shown below.

I shouldn't need to explicitly add the private header directories to my INCLUDE environment variables, should I? There would potentially be many of them. I'd expect them to be found automatically in some way... How is this done?

From the CMakeError.log file:

/opt/anss/bin/g++   -DQT_CORE_LIB -DQT_GUI_LIB -DQT_NO_DEBUG -fno-exceptions -fno-strict-aliasing -fno-rtti -std=c++11 -DQt5Gui_PRIVATE_HEADER_FOUND -I/home/staff/rmhoffma/Qt/QtBuildBin/include -I/home/staff/rmhoffma/Qt/QtBuildBin/include/QtGui -I/home/staff/rmhoffma/Qt/QtBuildBin/include/QtCore -I/home/staff/rmhoffma/Qt/QtBuildBin/./mkspecs/linux-g++    -fPIC -o CMakeFiles/cmTryCompileExec1880278613.dir/src.cxx.o -c /home/staff/rmhoffma/Qt/QtBuilds/qtwebkitBuild/release/CMakeFiles/CMakeTmp/src.cxx

Thanks for any assistance...

[Konstantin Tokarev]

CMake caches results of compilation tests in build directory (in CMakeCache.txt file), so I guess that you've fixed issue with unresolved libraries successfully but didn't clear cache after that

[RaymondH]

I delete everything from my build directory before running make, including any CMakeCache.txt file. Unless there is another location that files are stored on building, I believe I'm starting with a clean slate.

[Konstantin Tokarev]

@RaymondH said in Performing Test Qt5Gui_PRIVATE_HEADER_FOUND - Failed:

-DQt5Gui_PRIVATE_HEADER_FOUND

What is in CMakeError.log if you don't add -DQt5Gui_PRIVATE_HEADER_FOUND?

[RaymondH]

This is an automated script - i.e. it's configuring things using the OptionsQt.cmake file. I am not adding any parameters manually. How do I remove parameters that I didn't add and are added atomatically?

[RaymondH]

This post is deleted!

[Konstantin Tokarev]

Ok, seems like you are just missing Qt5Gui_PRIVATE_INCLUDE_DIRS cmake variable in Qt5GuiConfig.cmake now

[RaymondH]

So are you suggesting I make changes to the Qt installation to make my compilation work? I wouldn't think that should be necessary...

The file is located at: <QtInstall>/lib/cmake/Qt5Gui/Qt5GuiConfig.cmake

There is logic in that file that is supposed to set the variable, but it is by-passed during this build because of the following conditional:

if (NOT TARGET Qt5::Gui)

Apparently, when this configuration step happens, the TARGET is Qt5::Gui, and hence this conditional branch is never entered.

However, removing this conditional causes the QtWebKit configuration to fail in many many other ways, so it's not as simple as removing it.

[Konstantin Tokarev]

Apparently, when this configuration step happens, the TARGET is Qt5::Gui

No, this condition means "if target Qt5::Gui wasn't defined yet" (sort of guard against double inclusion)

Qt5Gui_PRIVATE_INCLUDE_DIRS may be empty if you are using shadow build when building Qt, see https://bugreports.qt.io/browse/QTBUG-37417

[RaymondH]

Apparently a former build, or something, created the following files, which show up as new files when doing a git status command:

        Source/JavaScriptCore/disassembler/udis86/ud_optable.pyc
        Source/WebCore/inspector/CodeGeneratorInspectorStrings.pyc
        Source/WebKit2/Scripts/webkit2/__init__.pyc
        Source/WebKit2/Scripts/webkit2/messages.pyc
        Source/WebKit2/Scripts/webkit2/model.pyc
        Source/WebKit2/Scripts/webkit2/parser.pyc

Once I delete these files, and reconfigure, the problem seems to have gone away.

Thanks Konstantin for your time.
