Qt5 development primer

J Offline

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!

What is the url for the development branch for qt5?
git://gitorious.org/qt/qt5.git does not have modifications since December, and git://gitorious.org/qt/qt.git still contains 4.8

thanks

Every module has a separate git repository, with the exception of QtCore, QtNetwork, QtGui, they are in qtbase.

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:

    cd windows\ && ( if not exist Makefile C:\qt5\qt5_32\qtbase\bin\qmake C:

Run perl from cmd.exe, not Bash terminal.

I did run the command "perl init-repository" from cmd.exe directly.

Hello,

I am having some problems compiling Qt 5.1 in MAC OSX. I've followed all the steps from here: http://qt-project.org/wiki/Building_Qt_5_from_Git ...

But... when I called "make -j 4", after about one hour of compilling work, I've got this error:

@make[3]: *** No rule to make target /Users/paulopina/PlexusDynamics/qt5/qtbase/lib/libQt5QmlDevTools.a', needed by /Users/paulopina/PlexusDynamics/qt5/qtbase/bin/qmlmin'. Stop.

Just head into "qtdeclarative\src\qmldevtools"

Hi,

Same error as PauloPina, then heading to "qtdeclarative\src\qmldevtools" and doing a "make" doesn't solve the problem. The make "has nothing to do". Only the debug lib is created, how do I create the release?

Thanks

D Offline

make release

Yes, of course I've tried it ;-) but unsuccessfully

There's no reference to a 'release' keyword in the Makefile. Here's how the whole qtbase was configured:

$ ./configure -prefix $PWD/qtbase -opensource -nomake tests

I've reconfigured with -debug-and-release option, but still no release rule and other errors raised.
