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.

hmuelner · wrote on 22 Mar 2012, 08:29

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 ?

situ117 · wrote on 30 Mar 2012, 15:07

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

configure script was succesful after I installed this package.

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?

Philius · wrote on 6 May 2012, 04:36

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:

Also available for Mac OS X: macx-g++

(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.

thinks · wrote on 9 May 2012, 14:41

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 .

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.
