    Hi all,
    Have some difficulties in cross-compiling qt5 from sources on my windows host.
    Can confirm that I can create a good binary for the raspi os 64, so then the toolchain does not seem to be the problem.
    Have tried to trigger the configure command from both the command-line as from the minimalistic bash shell but the result is the same.
    This is the command I am using for the scope:

    ./configure -release -opengl es2 -eglfs -device linux-rasp-pi4-v3d-g++ -device-option CROSS_COMPILE=/c/SysGCC/raspberry64/bin/aarch64-linux-gnu- -sysroot /c/SysGCC/raspberry64/aarch64-linux-gnu/sysroot -prefix /c/usr/local/rpi-qt -extprefix /c/tmp/rpi-qt -opensource -confirm-license -skip qtscript -skip qtwayland -skip qtwebengine -nomake tests -make libs -no-use-gold-linker -v -recheck -L/c/SysGCC/raspberry64/aarch64-linux-gnu/sysroot/usr/lib/aarch64-linux-gnu -I/c/SysGCC/raspberry64/aarch64-linux-gnu/sysroot/usr/include/aarch64-linux-gnu

    But the configure scripts stops immediately with the following message:
    "The build script does not currently recognize all
    platforms supported by Qt.
    Rerun this script with a -platform option listed to
    set the system/compiler combination you use."

    While on the command prompt when using:
    configure -release -opengl es2 -eglfs -device linux-rasp-pi4-v3d-g++ -device-option CROSS_COMPILE=c:\SysGCC\raspberry64\bin\aarch64-linux-gnu- -sysroot c:\SysGCC\raspberry64\aarch64-linux-gnu\sysroot -prefix c:\usr\local\rpi-qt -extprefix c:\tmp\rpi-qt -opensource -confirm-license -skip qtscript -skip qtwayland -skip qtwebengine -nomake tests -make libs -no-use-gold-linker -v -recheck -Lc:\SysGCC\raspberry64\aarch64-linux-gnu\sysroot\usr\lib\aarch64-linux-gnu -Ic:\SysGCC\raspberry64\aarch64-linux-gnu\sysroot\usr\include\aarch64-linux-gnu

    I get:

    "+ cd qtbase

    • c:\tmp\qt-everywhere-src-5.15.5\qtbase\configure.bat -top-level -release -opengl es2 -eglfs -device linux-rasp-pi4-v3d-g++ -device-option CROSS_COMPILE=c:\SysGCC\raspberry64\bin\aarch64-linux-gnu- -sysroot c:\SysGCC\raspberry64\aarch64-linux-gnu\sysroot -prefix c:\usr\local\rpi-qt -extprefix c:\tmp\rpi-qt -opensource -confirm-license -skip qtscript -skip qtwayland -skip qtwebengine -nomake tests -make libs -no-use-gold-linker -v -recheck -Lc:\SysGCC\raspberry64\aarch64-linux-gnu\sysroot\usr\lib\aarch64-linux-gnu -Ic:\SysGCC\raspberry64\aarch64-linux-gnu\sysroot\usr\include\aarch64-linux-gnu
      Cannot detect host toolchain. Please use -platform. Aborting."

    Thanks for any help in advance.

      Maybe it would be useful to set:
      -hostprefix ~/PATH_TO_QT_HOST_BUILD

        Thanks but unfortunately on a windows platform the cross-compilation for the raspios 64 is almost impossible without specific and hard qt cmake targets hacking.
        This guide for instance is not applicable:
        https://wiki.qt.io/Cross-Compile_Qt_6_for_Raspberry_Pi
        as the configure script will prompt for the double-conversion and md4c includes and libs - which in ANY case, even if copied from the raspios 64 target to the host sysroot WILL NOT work - also there seem to be a coming back issue with the opengl subsytem - even if forced to be es2 the build scripts is not going to use it EVEN IF it checks and FINDS both egl includes and libs.
        I am not going to add any further words as I do not want to pass for a brute guy - the whole configuration and deploy preparation phase of qt for a cross-compilation is (YOU KNOW WHAT).

            QT_FEATURE_opengles2 = "OFF" - It seems there could be a problem with libGLESv2.so/libEGL.so in sysroot/*.

            You can open C:/tmp/qt-everywhere-src-6.3.0/build/CMakeFiles/CMakeError.log file and check/share error for tests: HAVE_EGL and HAVE_GLESv2

              @Tatiana-Borisova said in Can not crosscompile qt5 for raspberry pi4 from windows host:

              HAVE_EGL

              Thanks again Tatiana,
              It seems not a your fault, excuse my hard words.
              The sysprogs toolchain I am using is not usable for X11 applications deployment as it lacks many headers and videocore libraries.

                If you don't need X11, but still wish to use graphic like eglfs, you can delete all XCB_*** flags from toolchain.cmake file.
                Plus delete following from config command: -DQT_FEATURE_xcb=ON -DFEATURE_xcb_xlib=ON -DQT_FEATURE_xlib=ON
