    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:
                      @######################################################################

                      ######################################################################

                      QT += widgets
                      TEMPLATE = app
                      TARGET = test03withoutCreator
                      DEPENDPATH += .
                      INCLUDEPATH += .

                      Input

                      SOURCES += main.cpp
                      @

                      main.cpp
                      @#include <QGuiApplication>
                      #include <QPushButton>

                      Q_DECL_EXPORT int main(int argc, char *argv[]){
                      QGuiApplication app(argc, argv);

                      QPushButton button("work");
                      button.show();
                      
                      return app.exec(&#41;;
                      

                      }@

                      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?

                          -You should be running configure.exe on windows, not the bash script.-

                          Add a file named ".gitignore" to the root folder or comment out line 45 in configure.bat.

                            After several failed attempts at building, here's how I finally managed to get QT5 to build with Nuwen.net's MinGW 9.4, on Windows 7 64 bit SP1 without webkit.

                            I already had Nuwen's mingw 9.4 installed (9.5 is now available), this can be obtained from http://www.nuwen.net/mingw.html

                            This needs to be extracted to c:\mingw or similar, and c:\mingw\bin will need to be in the PATH env variable.

                            Then I copied c:\mingw\bin\make.exe to c:\mingw\bin\mingw32-make.exe

                            I then downloaded and installed the following:

                            http://www.python.org/ftp/python/3.3.0/python-3.3.0.amd64.msi
                            http://files.rubyforge.vm.bytemark.co.uk/rubyinstaller/rubyinstaller-1.9.3-p362.exe
                            http://downloads.activestate.com/ActivePerl/releases/5.16.1.1601/ActivePerl-5.16.1.1601-MSWin32-x64-296175.msi
                            https://msysgit.googlecode.com/files/Git-1.8.0-preview20121022.exe

                            I used the installers to set the path for python, ruby and perl.

                            I downloaded QT5 (27th Dec 2012):

                            git clone git://gitorious.org/qt/qt5.git qt5
                            cd qt5
                            perl init-repository

                            Configured QT5:

                            configure -developer-build -opensource -nomake examples -nomake tests -qt-pcre -qt-libjpeg -opengl desktop

                            • Configure informed me that webkit would not be built due to a missing dependency, so no additional parameters were required to disable this.
                            • I have an ATi Radeon graphics driver with builtin OpenGL support
                            • By default configure sets pcre to 'system' at one point I downloaded and built the latest version of pcre, including the pcre16 library, I placed this into my system path, but ld was still unable to locate the library and there was no means of passing the -L parameter to ld from what I can tell, build would fail with 'unable to locate pcre16', once you specify -qt-pcre as per the above, the build will use the embedded pcre library and magically succeed.
                            • Again, for me, build would fail without specifying -qt-libjpeg

                            I then simply ran 'make'

                            Good luck!

                              git://gitorious.org/qt/qt5.git does not have modifications since December, and git://gitorious.org/qt/qt.git still contains 4.8

                                      Hi, I've succeed with compiling QT5 for arm (raspberry pi) what is not working for me is localized keyboard input in eglfs. When i use loadkeys de.kmap and than start an application. The keyboard is again Generic (US). But in console localized keyboard works. Did I miss something in compile or programming time?

                                        Hi yeckel,

                                        I don't have any experience with the Raspberry Pi, but I recommend posting your question in the "Qt Project Mobile and Embedded subforum":http://qt-project.org/forums/viewforum/11/ or the "Raspberry Pi forum":http://www.raspberrypi.org/phpBB3/

                                          Hello,

                                          I am trying to compile qt5.0.1 in 32bits mode using msvc2012 on a 64bits machine. I have succesfully build the exactly same sources in 64bits mode, many times.

                                          So I opened a "vs2012-x86 native tools command prompt" and just did exactly the same steps as i did to compile the 64bits version.

                                          After a long time, in the nmake phase, I encountered the following error:
