Cross compile Qt 5.5 on Windows 7 error missing <X11/Xutil.h.

  • Hello everyone,

    currently I'm trying to cross compile Qt 5.5 on Windows 7 for Raspberry 2 with Rasbian Jessie.
    I'm following this tutorial and most steps work fine but on step 17 I get an error when running make:

    J:/OpenSource/Qt/5.5.1/qt-everywhere-opensource-src-5.5.1/qtbase/src/plugins/platforms/xcb/qxcbmime.cpp:41:23: fatal error: X11/Xutil.h: No such file or directory
     #include <X11/Xutil.h>
    compilation terminated.
    make[6]: *** [.obj/qxcbmime.obj] Error 1
    make[6]: Leaving directory `/J/OpenSource/Qt/5.5.1/qt-build/qtbase/src/plugins/platforms/xcb'
    make[5]: *** [sub-xcb_qpa_lib-pro-make_first-ordered] Error 2
    make[5]: Leaving directory `/J/OpenSource/Qt/5.5.1/qt-build/qtbase/src/plugins/platforms/xcb'

    make[2]: Leaving directory `/J/OpenSource/Qt/5.5.1/qt-build/qtbase/src'
    make[1]: *** [sub-src-make_first] Error 2
    make[1]: Leaving directory `/J/OpenSource/Qt/5.5.1/qt-build/qtbase'
    make: *** [module-qtbase-make_first] Error 2

    I've tried googling without any success so far. I'm not sure where X11/Xutil.h is supposed to be. The path itself should be fine.

    As a note: I've tried compiling 5.6 before but there I failed way earlier when running make. There it failed on this part (and the other definitions in there):

    In file included from j:\tools\sysgcc\mingw32\include\security.h:40:0,
                     from J:/OpenSource/Qt/5.6/qt-everywhere-opensource-src-5.6.0/qtbase/src/corelib/io/qfilesystemengine_win.cpp:67:
    j:\tools\sysgcc\mingw32\include\secext.h:16:17: error: redeclaration of 'NameUnknown'
       NameUnknown = 0, 

    My Toolchain is pretty similar in both cases and I'm happy for help with any of the problem.
    Some more information that might be helpful:

    • I'm running Windows 7 Professional 64bit
    • The Raspberry Pi 2 is a model B+ with Raspbian Jessie installed. It was updated from Wheezy for this progress with dist-upgrade which went without errors. I only installed libxcbl-dev and resynchronized because otherwise configure woul fail with this xcb error message and OpenGL 2 ES.
    • I've used the toolchains from the linked tutorial.
    • GCC is located in /j/Tools/SysGCC/MinGW32/bin/gcc.exe
    • The architecture location is /j/Tools/SysGCC/Raspberry/bin/arm-linux-gnueabihf-gcc.exe
    • Qt source code is in J:\OpenSource\Qt\5.5.1\qt-everywhere-opensource-src-5.5.1 and with 5.6. in the path in the newer version.

    If you need any more info I'll try to provide it.
    I'm grateful for any hints! Thank you.
