    @thinks, did you try to "build the 5.0 alpha":http://qt-project.org/wiki/Qt-5-Alpha-building-instructions instead? Might be easier than building from git.

      Thanks, Ludde! :)

      We finally got it working here. The following was required:

      • Grab latest from Qt5 git repo.
        git clone git://gitorious.org/qt/qt5.git qt5

      • Use Qt's provided tool to initialize the repo.
        cd qt5
        perl init-repository --no-webkit

      • Set up our build environment.
        unset QTDIR
        export PATH="$PWD/qtbase/bin:$PWD/qtrepotools/bin:$PATH"
        export PATH=/Applications/XCode.app/Contents/Developer/usr/bin:$PATH
        export CPP=clang++
        export CC=clang
        echo PATH $PATH

      • Pre-build configuration. Note that we are forcing it to build using
        the Xcode compilers.
        ./configure -no-pch -developer-build -confirm-license -opensource
        -release -nomake demos -nomake examples -arch x86 -sdk
        /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk

      • Build. We could increase the number of course to improve speed once
        we are convinced that this works well...
        ./build -j 1

      Not sure all of that stuff is required though, but because the build time is quite steep (even with j > 1) we didn't have time to narrow it down.

      Cheers,

      T

        hi .

        I am currently doing the Qt5 manipulation and I have one little question ^^ .

        Is it possible to realize a configuration (./configure) in static Qt5 mode (-static) by incorporing the QtSerialPort class, which we must add to our pre-existing library thanks to that manipulation: http://qt-project.org/wiki/QtSerialPort ?

        If this is not possible to change QtSerialPort in static library, but just the QT5 library . When I will compile my project which uses QtSerialPort, will it run like a static program or I need to include a .so (or dll) ?

        Sorry for my bad english .

            Seems related to bluetooth, but since I don't know bluez very well, I don't know where to look at.

              Have you updated QTDIR and PATH before starting the build? It seems that your search paths are polluted, or bluetooth.h - maybe - bluetooth.h is not ready for C++11, or something entirely different is happening :P.

                This issue happened to me quite recently actually. (< 2 weeks) my bluetooth.h did not had any problems before ...

                      On MAC I encountered a problem: Under the last version of XCode you have to download the "command lines tools" seperatly from the xcode settings in the downloads pane.

                        I was getting "The Remote End Hung up Unexpectedly" when running "perl init-repository". I found that if I used the "-http" option at the end of that line, the failures stopped. It seems that the "git" protocol is a bit flaky. Making http the default in the "init-repository" script would make the process a bit more robust.

                          You can also rerun the script with "-f". Doesn't fix git protocol, but often it works on second try.

                            Yeah, unfortunately for me, re-runnng w/git kept failing at different points.

                              Hi,
                              I'm new to command line compiling and Git.

                              Thanks to the excellent "guide":http://qt-project.org/wiki/Building_Qt_5_from_Git I was able to build Qt from source. Now, with the latest beta 2 release, I'd like to update Qt.

                              My question is simple:

                              Do I need to run configure after:

                              git pull
                              git submodule update --recursive

                              Or can I just run make again without doing that?

                              A suggestion would be to update the "Getting Updates" section to include this answer as maybe others would wonder if they need to do that too.

                              Thanks,
                              Brett

                                Tricky. Depends on what has changed in the source code, really. If you have a solid CPU and a bit of time on your hands, you can definitely try just running make, and then if it fails, you should do a proper clean (git clean -dxf, check the link you provided for a submodule declaration), configure and make.

                                  Thanks for your post. I modified the wiki page updates section with a note that clean and configure may need to be re-run.

                                    I'm building on windows 7 x64 with msvc2010 sp1 nmake.

                                    For some reason the naming convention is different then the beta release and incompatible with the vs-addin..

                                    All my lib files, dll files etc are named Qt5[lib].dll/lib instead of Qt[lib]5.dll/lib

                                    My config: configure -developer-build -opensource -nomake examples -nomake tests

                                        Hi,

                                        First I have setup qt5 (both with the linux birnary file and by compiling it) on an Ubuntu 12.04 (and 11.10) KVM virtual machine. But I can't launch any graphical qt program. I have issue with QPainter: that kind of mistakes:

                                        @cedric@cedric-virtual-machine:~/Qt5.0.0beta2/5.0.0-beta2/gcc/bin$ ./assistant
                                        QWidget::paintEngine: Should no longer be called
                                        QPainter::begin: Paint device returned engine == 0, type: 1
                                        QWidget::paintEngine: Should no longer be called
                                        QPainter::begin: Paint device returned engine == 0, type: 1
                                        QPainter::font: Painter not active
                                        QPainter::pen: Painter not active
                                        ...@

                                        So I tried on a windows 32 bits virtual machine. First I installed it with the binary but I couldn't find our the right microsoft compiler so it could work. So I tryed to compile it with mingw32-make. It worked with the following config:
                                        @configure -platform win32-g++ -opengl desktop@
                                        Yeah I couldn't find the right version of direct X sdk so I had some issue and choose to use the opengl option.

                                        This version doesn't work with qt creator. I don't know if it is suppoed to? I have an issue with "ABI detection failed. Make sur to use a matching compiler when building. No qml viewer." But I can launch the program named qmlviewer.exe. Also I can compile the following application with qmake.

                                        pro file:

                                        button.show();

                                        }@

                                        but then, I have no idea how to launch it. I did:
                                        @qmake
                                        mingw32-make release@
                                        Then I put the binary file in qtbase/bin, but I when I launch the application, I get the following message:
                                        "This application has requested the runtime to terminate it in an unusual way."
                                        But the exemples and demos can be launch without any dll in their direcotry. I don't get how that is possible.

                                        Someone know what I should do so I can compile and launch application?

                                        Sincerly,

                                        Cédric

                                          I'm having trouble building the final release on Windows 7 x64 with both VS2008 and VS2012. I have ActivePerl and Python 2.7 installed and in the path, and in both cases when I run "configure" I get this error:
                                          @
                                          'T:\home\Qt\5.0.0\qtbase\configure.exe' is not recognized as an internal or external command, operable program or batch file.
                                          *** qtbase/configure exited with non-zero status.@

                                          Any ideas?
