Unofficial MinGW-based build of Qt 5.0.0 is now available

[quote author="alexpux" date="1357372790"]I try to rebuild my builds of Qt5 for mingw with some optimization after 8th january and upload them. You can test perfomance again.[/quote]
Hi, I've done some optimization to my algorithm - now MinGW performance is much better, but still somewhat lower than MSVC. In fact with the improved algorithm the MinGW version is a little faster than the old MSVC version. I wonder what could have caused performance to be so low before, the version of MinGW you have bundled should support all the C++11 features that increase performance, C++11 support in MinGW is a little better than that of MSVC2012. Anyway, here are the new results:
Qt5 MSVC2012 ×64:

!http://i49.tinypic.com/2uj6pmt.png(MinGW)!Now the performance difference is only 0.3x - much better than 4x. So the build is not that slow, as long as you code efficiently. It is still a little slower than Qt4 MinGW x86 - which gets 30 MCPS performance.

can you provide more information about your testing system? I can't agree with your results. I'm experiencing average 5% of speedup with MinGW x64 compared with MSVC 2012 :/
My PC: intel Dual Core 2.4 GHz @ 4GB RAM ~ Windows 7 64 bit
MinGW
Optimization flags: "-O3 -mtune=native"
Threading model: POSIXMSVC
Optimization flags: "/Ox" -
My builds that uploaded to sourceforge.net are builded without any optimization.

Thanks for the pre-compiled package. I uncompress it and place it to c:/, and I am going to use the qt library in mingw. With qt4, I compile my source in mingw as
./configure --prefix=SOMEWHERE LIBS="-L /c/Qt/4.8.4/lib -lmingw32 -lqtmain -lQtGui4 -lQtCore4"
make
make installthat is, the libraries flag qtmain, QtGui4 and QtCore4, etc. were setup well upon the installation of qt4. But with this pre-compiled package of qt5, obviously, it won't set it up, so what to do to make it work with pkg-config so the mingw know how to compile my
code with qt dependency.BTW, I found three folders in the package, if I only need the mingw32 compilation, so I only have to copy everything inside mingw32 folder and place them to the mingw root folder, right?
Thanks.

Hi all!
I create new project on https://github.com/Alexpux/Qt-builds where is the set of scripts to build Qt5+QtCreator with all its prerequisites and dependencies under MSYS. -
[quote author="alexpux" date="1358269379"]Do you change links to toolchains or use my links?[/quote]
I used yours. The toolchains downloaded but there was no command in your script to unzip them.
Currently the qt5 configure is failing, that might be because I changed some of the flags (I added -no-exceptions -no-rtti -no-stl)
Update apparently -no-exceptions and -no-stl are no longer an option in qt5.

I am not aware of the current state of affairs, but Qt 5.0.1 repos were merged into stable a weak ago and should be pretty much finalized and can be found "here":http://releases.qt-project.org/digia/5.0.1/latest_successful/
There is a MinGW version there for the impatient :)
-
Ok I do build of Qt-5.0.1 with QtCreator-2.6.1 for 32-bit. You can download it from http://sourceforge.net/projects/mingwbuilds/files/external-binary-packages/Qt-Builds/Qt-5.0.1-x32.7z/download
-
@alexpux: Thank you for being so helpful to Qt users! The Qt 5.0.1 release will contain an official MinGW-based build, so you can probably rest from compiling Qt after that :) Your scripts will be useful a long time to come though.
Thanks again!
-
Ok I post here the last link for my build. This is 64-bit build for Qt-5.0.1 + QtCreator-2.6.1
http://sourceforge.net/projects/mingwbuilds/files/external-binary-packages/Qt-Builds/Qt-5.0.1-x64.7z/download
I f anyone need my builds later you can find them on http://sourceforge.net/projects/mingwbuilds/files/external-binary-packages/Qt-Builds. My plans to future is to add qbs and cmake to builds, and make installer or qpatch to make my builds relocatable. -
I remove obsoleted SDK-x32 and SDK-x64 from links in first post. Instead they I upload my last release of Qt-5.0.0.
Now my builds contains QBS and QDesktopComponents. And you can simply move Qt folder where you want by editing qt.conf file in <QTDIR>/bin directory.
Also I now have static builds of Qt5.
I will no longer update the information here.
All information of my builds and next releases you can find:"Qt Wiki":http://qt-project.org/wiki/MinGW-64-bit

Hello,
I am facing problems when compiling my project with your pre-built package (Qt-5.0.1-x64.7z). Actually I have the exact same problem with my own compilation of qt5.0.1/mingw64. I am using this mingw: x64-4.7.2-release-posix-sjlj-rev8.7z. My application compiles fine with the official mingw32 release or msvc2010/32bits release, and even with my own qt5.0.1/msvc2012/64bits build. But I can't seem to be able to compile with qt5/mingw64...
I have plenty of errors like that:

[/code]I have tried many things.. no way. Any idea what I am doing wrong with the setup?
Thanks
