Unable to build qtx11extras module in Qt 5.15.5
-
I seem unable to to build the qtx11extras module that I require to build my application. I will detail all steps taken below.
I have downloaded Qt 5.15.5 source and extracted it. I build Qt using a shadow build like so:
Directory structure:
.../Qt/qt-everywhere-src-5.15.5/ .../Qt/qt5-build/ .../Qt/5.15.5-RHEL7/From qt5-build, I call configure (note: platform is linux-g++):
../qt-everywhere-src-5.15.5/configure -opensource -debug -nomake examples -nomake tests -prefix ../5.15.5-RHEL7Then I call
gmakeandgmake install, and Qt builds without errors. When I look at the qtx11extras module subfolder in my build dir and install dir, both are empty except for a makefile and an empty src dir (also has a makefile).Following advice given here, I then attempt to build the module by itself by calling
gmake module-qtx11extrasfrom my build dir. The output from this command shows it cd'ing into each module directory and subdirs and doing nothing until it reaches the qtx11extras module directory, for which the output looks basically the same as the others:cd qtx11extras/ && ( test -e Makefile || /myPath/Qt/qt5-build/qtbase/bin/qmake -o Makefile /myPath/Qt/qt-everywhere-src-5.15.5/qtx11extras/qtx11extras.pro ) && make -f Makefile make[1]: Entering directory '/myPath/Qt/qt5-build/qtx11extras' cd src/ && ( test -e Makefile || /myPath/Qt/qt5-build/qtbase/bin/qmake -o Makefile /myPath/Qt/qt-everywhere-src-5.15.5/qtx11extras/src/src.pro ) && make -f Makefile make[2]: Entering directory '/myPath/Qt/qt5-build/qtx11extras/src' make[2]: Nothing to be done for 'first'. make[2]: Leaving directory '/myPath/Qt/qt5-build/qtx11extras/src' make[1]: Leaving directory '/myPath/Qt/qt5-build/qtx11extras'And nothing happens. Do I need to run another configure command specific to the module first?

From that config.log:
looking for library xcb_icccm Trying source 0 (type pkgConfig) of library xcb_icccm ... + /bin/pkg-config --exists --silence-errors xcb-icccm '>=' 0.3.9 pkg-config did not find package. => source produced no result. Trying source 1 (type inline) of library xcb_icccm ... xcb/xcb_icccm.h not found in [] and global paths. => source produced no result. test config.qtbase_gui.libraries.xcb_icccm FAILEDIt looks like this may be the problem since xcb-icccm is listed as an X11 requirement. However, I can't seem to find this package on CentOS7 with
yum list | grep xcb-icccm(or grepping for 'xcb' or 'icccm' separately). A cursory google search suggest I may need to be looking forxcb-util-wminstead, but I already have this installed...Is anyone able to chime in here with further insight? Sorry if this is a dumb question, I'm fairly new to building on Linux :)

@JW16 said in Unable to build qtx11extras module in Qt 5.15.5:
xcb-util-wm instead, but I already have this installed
Also its dev package?

@jsulm Yes, installing the "-devel" counterpart to all of the xcb related packages I had installed worked. Thanks.
I'm having this same issue trying to build Qt 5.15.8 from source on CentOS7 even with the header file /usr/include/xcb/xcb_icccm.h already installed on the system. (The following xcb package are installed: libxcb.x86_64 libxcb-devel.x86_64 xcb-util.x86_64 xcb-util-devel.x86_64 xcb-util-image.x86_64 xcb-util-image-devel.x86_64 xcb-util-wm.x86_64 xcb-util-wm-devel.x86_64). I can see in the config.log it continues to search and test for xcb packages, i.e, it currently cannot find xcb-keysyms. But it's not clear to me faulting through this output and piecemeal installing more xcb packages will ultimately trigger qt11extras to build/install - more specifically export the needed header files to live under <install path>/include/QtX11Extras/* during the install pass. I don't see configure options describing how to install X11 related modules or files in the help output from configure. The options do not seem to directly relate to telling Qt to build a specific module under the top level source tree like qt11extras. As the poster listed above, it does not work to cd into qtbase and type "gmake module-qtbase" . I don't see a target in the 700+ line Makefile there as generated by configure to build qtx11extras.

@qa_test What exact error do you get?
-
I would guess it's the usual suspect xkbcommon like here: https://forum.qt.io/topic/143128/qt-everywhere-src-5-15-2-fails-to-build-xcb-plation

I went back to the list of what should be installed as shown under, https://doc.qt.io/qt-5/linux-requirements.html. I did end up installing some xcb common and other packages. (See below for summary of some installed packages).
There are no errors during the build (using the recommended gcc/g++ 5.3.1 via devtoolset-4) and install of the qt source from the downloaded file, qt-everywhere-opensource-src-5.15.8.zip, on my CentOS7 system. For the configure command, I used,
$ configure --prefix=$HOME/qt-install -confirm-license -opensource -release -shared -nomake examples -nomake tests -verboseBut when I point the applications build sandbox that links against Qt to that 5.15.8 install tree via adding -DQt5_DIR=$HOME/qt-install/lib/cmake/Qt5 on the cmake command line, cmake flags Qt5X11Extras is missing for a build target.
-- Could NOT find Qt5X11Extras (missing: Qt5X11Extras_DIR) CMake Warning at cmake/FindQT.cmake:18 (find_package): Found package configuration file: <$HOME>/qt-install/lib/cmake/Qt5/Qt5Config.cmake but it set Qt5_FOUND to FALSE so package "Qt5" is considered to be NOT FOUND. Reason given by package: Failed to find Qt5 component "X11Extras" config file at <$HOME>/qt-install/lib/cmake/Qt5X11Extras/Qt5X11Ext Target "<foo>" links to target "Qt5::X11Extras" but the target was not found. Perhaps a find_package() call is missing for an IMPORTED target, or an ALIAS target is missing?What was installed uner $HOME/qt-install/lib/cmake is the folowing,
