    The thing is that the host is linux, that's why the Win32MakefileGenerator is even more confusing. I deleted all the modified flies, at least all that git said were different. I'll try to clone again just in case some files got ignored and didn't show up in git.

      Ok that was one reason, apparently some stuff stays from old builds and it's not shown in git.
      Now the only issue is I get the ERROR: Unknown command line option -skip, if I understand right it should be used to not build unsupported modules.
      But it does say

      Creating qmake...
      .Done.
      ERROR: Unknown command line option -skip
      

      So not sure if that's something that can be ignored.

        Ah, ok sorry I got confused :-)

        If you use git and clean it (git clean -dxf) make sure the repo is initialized.

        Best way to safely compile Qt is to do an out of source build:

        git clone ...
        cd repo
        perl init-repository
        cd ..
        mkdir build 
        cd build
        ../repo/configure ...
        

        Easier yet - use a tarball from qt.io archive. It's a faster download, no need to init-repository, in general just less hassle.

          Here is a script I use to compile Qt on Android, maybe it will help you. Host is Kubuntu 18.10 in this case.

          export QTVER=5.11.1
              wget http://download.qt.io/official_releases/qt/5.11/$QTVER/single/qt-everywhere-src-$QTVER.tar.xz
              tar -xaf qt-everywhere-src-$QTVER.tar.xz
              mv qt-everywhere-src-$QTVER $QTVER-src
              mkdir qtbuild
              cd qtbuild
              # Check if this path is correct
              export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64
              export ANDROID_NDK_ROOT=/path/to/android/ndk-r10e
              ../$QTVER-src/configure -release -xplatform android-g++ --disable-rpath -nomake tests -nomake examples -android-ndk-host linux-x86_64 -android-toolchain-version 4.9 -android-ndk $ANDROID_NDK_ROOT -android-sdk /path/to/android/sdk -no-warnings-are-errors -opensource -confirm-license -prefix ../$QTVER-android -skip qttranslations -skip qtserialport -skip qtserialbus -skip qtscxml -skip qtscript -skip qtcharts -skip qt3d -skip qtdatavis3d -skip qtcanvas3d -skip qtgamepad -skip qtvirtualkeyboard -skip qtwayland -skip qtwebengine -skip qtwebchannel -skip qtwebsockets -android-arch armeabi-v7a
              time make -j `nproc`
              make install
          

          You may want to experiment with some OpenSSL flags, too, but I've left them out to make it easier.

            Nope. Your build dir or environment is seriously wrong if it fails to recognise -skip.

              Thanks for the help, I'll play around with settings.
              First I'll try to download the zip because using perl init-repository just ends up with Can't open perl script "init-repository" no such file or directory, and first I do cd qtbase, so who knows what's not working correctly.

                Ok I simply have no luck.
                I downloaded the tar 5 times, and every time
                wget http://download.qt.io/official_releases/qt/5.11/5.11.1/single/qt-everywhere-src-5.11.1.tar.xz

                ~/source_qt $ tar -xaf qt-everywhere-src-5.11.1.tar.xz 
                xz: (stdin): Compressed data is corrupt
                tar: Unexpected EOF in archive
                tar: Unexpected EOF in archive
                tar: Error is not recoverable: exiting now
                

                I'll continue trying with the git source... :S

                  Hi,

                  The .zip archive is for Windows.
                  The .tar.xz archive is for Linux.

                  Completely unrelated to the target you want to build for, it's a question of line ending type.

                    It is for linux, I tried one more time and now it was ok. Only thing is that's not what I need, since I can't edit the files like this, so I still have to use the git version.

                      The mystery about -skip not found is simply because I was building the wrong repo the whole time qtbase instead of qt5, that's also why the perl init-repository didn't work...
                      I feel a bit stupid, but now I know something new.
                      Thank you all for the help.

                        No worries :-) Building Qt is a complex thing, I guess we all understand it and went through similar hurdles at some point in the past ;-) Happy coding!
