Cross Compile Qt

  • I'm trying to cross-compile Qt5.9.3 host(MinGw64 - 5.3.0 - officially supported) target(RPI 3 Stretch linux arm toolchain)

    C:\Qt\Qt5.9.3\qt-build>C:\Qt\Qt5.9.3\configure -platform win32-g++ -xplatform linux-arm-gnueabi-g++ -release -linuxfb -device linux-rasp-pi3-g++ -sysroot C:/SysGCC/Raspberry/arm-linux-gnueabihf/sysroot
    + cd qtbase
    + C:\Qt\Qt5.9.3\qtbase\configure.bat -top-level -platform win32-g++ -xplatform linux-arm-gnueabi-g++ -release -linuxfb -device linux-rasp-pi3-g++ -sysroot C:/SysGCC/Raspberry/arm-linux-gnueabihf/sysroot
    Bootstrapping qmake ...
    mingw32-make: Nothing to be done for 'first'.
    ERROR: Cannot specify both -xplatform and -device.

    It seems it's the only way(using xplatform and device parameters) to cross compile qt?

    Just remove the -xplatform option as the -device option should set everything needed for cross-compilation tailored to that device.
