    @pierrevr: I am talking about building Webkit on Windows - no package manager there.

      Hello, I have tried to compile Qt5 under archlinux and under mac os, but in both cases I have got the same errors:

      bq.
      cd qtsvg/ && make -f Makefile
      cd qtphonon/ && make -f Makefile
      cd qtxmlpatterns/ && make -f Makefile

      make: *** [module-qtphonon-make_default] Error 2

      I have used the next command:

      bq. git clone git://gitorious.org/qt/qt5.git qt5 && cd qt5 && perl init-repository && export PATH="$PWD/qtbase/bin:$PATH" && ./configure -prefix $PWD/qt5 -opensource -confirm-license -nomake tests -nomake examples && make -j3

      In addition I would like to know how to compile Qt 5 for a special arch? (for example, how to compile Qt 5 for i386 arch on x86_64 OS?)

        I made some progress (but did not succeed) with compiling the current git version of qtwebkit with vs2010 in windows7(64):

        My Qt directory is in d:\Qt\qt5.

        • I created an additional system cpp directory in d:\cpp with an include and a lib subdirectory

        • I add two variables to my system environment: INCLUDE=d:\cpp\include and LIB=d:\cpp\lib and started a new Visual Studio Command Prompt.

        • I copied qedit.h from the Windows SDK 6.0A to d:\cpp\include

        • I got the ICU libraries form http://download.icu-project.org/files/icu4c/4.8.1.1/icu4c-4_8_1_1-Win32-msvc10.zip

        • I copied the icu headers ti d:\cpp\include

        • I copied the icu lib files (*.lib and *.dll) to d:\Qt\qt5\qtbase\lib

        • I renamed icuin.lib to icui18n.lib, icuind.lib to icui18nd.lib and icudt.lib to icudata.lib

        • I got ftp://sources.redhat.com/pub/pthreads-win32/pthreads-w32-2-8-0-release.exe for the pthread library

        • I copied the pthreads headers and libraries to d:\cpp\include and d:\cpp\lib

        • I changed one subroutine in d:/Qt/qt5/qtwebkit/Tools/Scripts/webkitdirs.pm to the following code (because the mkspec can be a ;-separated path list):
          @sub retrieveQMakespecVar
          {
          my $mkspec = $[0];
          my $varname = $
          [1];

          my $varvalue = undef;
          #print "retrieveMakespecVar " . $mkspec . ", " . $varname . "\n";
          my @mkspecs = split(/;/,$mkspec);
          foreach $mkspec (@mkspecs) {
          local SPEC;
          open (SPEC, "<$mkspec") or next;
          while (<SPEC>) {
          if ($_ =~ /\s

            Build qt5 on Windows 7 with VS2010 (next try, hope this is not a double post).

            I tried again with the version from 2012-03-21 with this configuration:

            configure -confirm-license -opensource -debug-and-release -platform win32-msvc2010 -fast -mp -opengl desktop -nomake tests -nomake examples

              Build qt5 on Windows 7 with VS2010 (continued)

              I could build all other modules (using nmake module-xxx) out of the box with the exception of qtmodule where moc could not parse dsserviceplugin.h because of a comma in Q_PLUGIN_METADATA. After correcting this it also built successfully.

                qtscript and qtwebkit contain different versions of JavaScriptCore - it looks like syncing qt5 modules does not yet work perfectly ;-)

                  Hi,

                  I am trying to build Qt5 on Chakra Linux. I have Xcb libraries installed, but when I start configuration script I get an error saying:

                  @No QPA platform plugin enabled!
                  If you really want to build without a QPA platform plugin you must pass
                  -no-xcb and -no-eglfs to configure. Doing this will
                  produce a Qt that cannot run GUI applications.
                  The dependencies needed for xcb to build are listed in
                  src/plugins/platforms/xcb/README@

                  What I am missing here ?

                    So the package I was missing was : xcb-util-keysyms

                    configure script was succesful after I installed this package.

                      i am facing compilation error in building qt5 (not webkit yet)
                      I am using Ubuntu, with all xcb and other dependency installed using apt-get

                      configure was successful, whereas build failed in "wayland" (error log below).
                      Any clue on the wayland header files mismatch or version problems?

                        Issue is solved after downloading the release from
                        http://releases.qt-project.org/qt5.0/alpha/

                        instead of GIT

                        [quote author="subbul" date="1333560508"] i am facing compilation error in building qt5 (not webkit yet)
                        I am using Ubuntu, with all xcb and other dependency installed using apt-get

                        configure was successful, whereas build failed in "wayland" (error log below).
                        Any clue on the wayland header files mismatch or version problems?

                            Hi, trying to build qtbase on WinXP using MSVC2008, followed the instructions exactly and it builds OK, but when when I try to run I get:

                            "Failed to load platform plugin "". Available platforms are: windows:

                            Any hints?

                              I am trying to build the qt5-alpha source from the zip download as I don't have git on my windows machine. Is there any way to do a "make clean"/"make confclean" without git?

                                I just happened to notice your posts - I didn't get an email notification.

                                According to configure, "To reconfigure, run 'make confclean' and 'configure'.".
                                Well you probably know that at least with Qt5 alpha, that doesn't work.

                                I'm on Debian so I can't offer any Windows wisdom, but for "make clean" I just delete the directory and re-unpack the alpha .tar.bz2 again.

                                I'm in the dark as to how to build/use the QtDeclarative component.
                                It appears that the header I'm looking for - "QtDeclarative/QDeclarativeComponent" isn't installed although it's in the source tree - yes I built/installed qtjsbackend and qtdeclarative.

                                Also, it would be nice if Qt5 beta had a top-level makefile that included targets for
                                linux-x86-32-gcc-x11
                                linux-x86-64-gcc-x11
                                windows7-64-msvc2010

                                and so on, so we could be sure we're building against a known and tested build configuration.

                                And yes, it should fail if any prerequisites are missing (and maybe print warnings if they are different versions).

                                  Hi All,

                                  I'm trying to building Qt5 om Mac OSX 10.7. Following the instructions given here:

                                  http://qt-project.org/wiki/Building_Qt_5_from_Git

                                  However, I'm running into an issue in the build-step which I'm not
                                  sure how to solve. One of the errors I'm getting is the following:

                                  gcc: error: tools/qlocale_mac.mm: Objective-C++ compiler not installed
                                  on this system

                                  I will give a detailed step-by-step descriptions of my process below,
                                  assuming the starting point to be a blank shell with PWD=$HOME:

                                  (1) git clone git://gitorious.org/qt/qt5.git qt5 [check!]

                                  (2) cd qt5 [check!] :)

                                  (3) perl init-repository --no-webkit [check! Does its job without complaining. I can provide the log if necessary]

                                  (4) unset QTDIR [check!] :)

                                  (5) export PATH="$PWD/qtbase/bin:$PWD/qtrepotools/bin:$PATH" [check!] :)

                                  (6) ./configure -developer-build -opensource -nomake examples -nomake
                                  tests [check! See below]

                                  Get a few warnings about some Qt header not containing macros, e.g.:

                                  QtCore: WARNING:
                                  /Users/thinks/qt5/qtbase/src/corelib/qtcoreversion.h does
                                  not include QT_BEGIN_HEADER

                                  but they don't seem severe. Other relevant output:

                                  Build type: macx-clang
                                  Architecture: x86_64
                                  Host architecture: x86_64
                                  Platform notes:

                                  (7) ./build -j 4

                                  This is where the trouble begins. The following (first) error is given:

                                  [Lots of output without errors...]
                                  qabstractanimation.h -o .moc/debug-shared/moc_qabstractanimation.cpp
                                  gcc: error: tools/qlocale_mac.mm: Objective-C++ compiler not installed
                                  on this system
                                  gcc: error: kernel/qcore_mac_objc.mm: Objective-C++ compiler not
                                  installed on this system

                                  Similar errors are reported further on as well, all with the same
                                  reason given. It seems somewhat strange that gcc is used over g++, but
                                  at the moment I'm not really sure why this happens.

                                  Some info about gcc:

                                  [thinks@wiggs ~] gcc --version
                                  gcc (GCC) 4.8.0 20120408 (experimental)

                                  Any advice greatly appreciated!

                                  Thanks,

                                  T

                                    @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.

                                        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 .
