    I'm a green hand at Qt on Android. I ran into some problems in my first try.
    Error

    /home/***/libs/android-ndk-r10/sources/cxx-stl/gnu-libstdc++/4.9/include/cstdlib:72: error: stdlib.h: No such file or directory
     #include <stdlib.h>
              ^
    

    Other output

    /bin/sh: 1: /home/***/libs/android-ndk-r10/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc: not found
    /bin/sh: 1: /home/***/libs/android-ndk-r10/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc: not found

    Kids

    • Ubuntu 16.04
    • Qt for Android 5.5
    • openjdk 80
    • ndk r23
    • ndk r10

    In fact, I've tried to include the .h files manually.
    The missing-header error disappeared,but,many more other errors came up.
    I thought I've set ndk incorrectly,but,I've no idea about how it should be arranged.
    It's such a mess.Could you tell me how to solve it or any docs or blogs that I need?

    @egg.nut Hi!
    Did you read http://doc.qt.io/qt-5/androidgs.html ?
    And you did not say what exactly you're trying to do?
    Are you trying to build a Qt application for android?
    Do you use QtCreator?

      In fact, I had been following http://doc.qt.io/qt-5/androidgs.html.
      To build an android app.
      With QtCreator.
      Only ONE THING went wrong that the SDK Manager couldn't fetch any file and said there were nothing to install or update.
      But,I don't think it causes this problem.
      Dose it?

        the SDK Manager pops a window:

          I manually changed the INCLUDEPATH, Qt found the headers but said:

          cannot open crtbegin_so.o: No such file or directory
          cannot open crtend_so.o: No such file or directory

          followed by many other errors.

            I set the INCLUDEPATH,
            make links of many files.
            and it works...
            But there must be something wrong:why these paths goes wrong.

            that's what I did:

            xiaodan@xiaodan-G41M-ES2L:~/qtproj/build-test_android-Android_for_armeabi_GCC_4_9_Qt_5_5_0-Debug$ ll

              @egg.nut Did you configure QtCreator properly? Last time I did something for Android everything was working just fine after setting up SDK/NDK/QtCreator (and Qt for Android).

              This one looks strange: android-arm -> android-arm64
              Are you trying to build for arm64?

                Firstly,I did set the kits and it seems all right.
                Secondly,there no android-arm fold under ndk/prebuild so I gave it a link.
                Thirdly,It really works...

                Everything is wrong, and it turns to be fine.

                It struck me that I only set the Qt.Is there anything to set in SDK or NDK?

                  I've seen a warning in Android Setting:
                  Qt versions for 3 architectures are missing.
                  Does this matters?
