Fatal error: .moc: No such file or directory while cross-compiling Qt



  • I am cross-compiling Qt5.12 for an ARM embedder linux device. I am not building inside the source directory, but into a parallel directory. This is my configure, it completes without any apparent error:

    ../qt-everywhere-src-5.12.11/configure -opensource -confirm-license -xplatform arm-cortex_a8-linux-gnueabi-g++ -prefix test2/ -no-opengl -no-pch -no-evdev -linuxfb -tslib -skip qtserialport -verbose -skip qtimageformats -skip qtsvg
    

    After that, the make command fails, giving me the following errors:

    /home/andrea/Scrivania/installQt/qt-everywhere-src-5.12.11/qtdeclarative/src/qml/util/qqmladaptormodel.cpp:1044:32: fatal error: qqmladaptormodel.moc: No such file or directory
     #include <qqmladaptormodel.moc>
                                    ^
    compilation terminated.
    make[3]: *** [Makefile:16851: .obj/qqmladaptormodel.o] Errore 1

    make: *** [Makefile:231: module-qtdeclarative-make_first] Errore 2
    

    Can anyone give me an hint on how to solve the issue, or about where to investigate?
    Thanks.

    Hi,

    Are you doing a multi-threaded build ?

    By the way, you are not building the latest of the 5.12 series.
