    @jsulm in config cache file i found this

    cache.webengine-fontconfig._KEYS_ = result msgs
cache.webengine-fontconfig.result = false
cache.webengine-fontconfig.msgs = "Trying source 0 (type pkgConfig) of library webengine-fontconfig ..." "+ /usr/bin/arm-linux-gnueabihf-pkg-config --exists --silence-errors fontconfig" "pkg-config did not find package." "  => source produced no result."

    can anyone tell me how to link fontconfig lib here.

    @mvsri Sorry, I don't know why it doesn't work. Maybe somebody else can help.

    @jsulm Hey there,
    I'm trying to install QT 5.12.8 with qtwebengine following the steps from this link
    https://www.tal.org/tutorials/building-qt-512-raspberry-pi

    when i'm using

    make

    i get the following error

    ninja: build stopped: subcommand failed.
make[4]: *** [Makefile.gn_run:1087: run_ninja] Error 1
make[4]: Leaving directory '/home/pi/Desktop/qt-everywhere-src-5.12.8/qtwebengine/src/core'
make[3]: *** [Makefile:82: sub-gn_run-pro-make_first] Error 2
make[3]: Leaving directory '/home/pi/Desktop/qt-everywhere-src-5.12.8/qtwebengine/src/core'
make[2]: *** [Makefile:81: sub-core-make_first] Error 2
make[2]: Leaving directory '/home/pi/Desktop/qt-everywhere-src-5.12.8/qtwebengine/src'
make[1]: *** [Makefile:49: sub-src-make_first] Error 2
make[1]: Leaving directory '/home/pi/Desktop/qt-everywhere-src-5.12.8/qtwebengine'
make: *** [Makefile:1005: module-qtwebengine-make_first] Error 2

    Do you have any idea what could the problem be?
    I also checked the file in path

    /home/pi/Desktop/qt-everywhere-src-5.12.8/qtwebengine/src/core/Makefile.gn_run

    it is as follows

    run_ninja:
ninja -v -C /home/pi/Desktop/qt-everywhere-src-5.12.8/qtwebengine/src/core/release QtWebEngineCore

    You did not post the actual errors, those should be above what you posted.

    Looks like your build artefacts use different ABIs than what is in third_party.
    How was third_party content build?

    @jsulm
    http://download.qt.io/official_releases/qt/5.12/5.12.8/single/qt-everywhere-src-5.12.8.tar.xz

    i downloaded it form here and followed this steps https://www.tal.org/tutorials/building-qt-512-raspberry-pi

    according to that i can say that 3rd party content also built along with the code
