&quot;MinGW-builds&amp;quot;: http://sourceforge.net/projects/mingwbuilds/ : a binary package by developer: niXman, lexx83 (Alexpux). Provides both packages with a 32-bit and a 64-bit compiler (Windows host), that can also cross-compile to 32-bit or 64-bit. Packages are available with both &quot;posix&amp;quot; and &quot;win32&amp;quot; threading libraries, for 32 bit also with sjlj or dwarf exception variants. See also MSYS2.

=== [[MSYS2]] ===


&quot;MSYS2&amp;quot;: http://sourceforge.net/projects/msys2/ : MSYS2 (Minimal SYStem 2) is an independent rewrite of MSYS, a (command-line) shell for development usage, and based on modern Cygwin (POSIX compatibility layer) and MinGW-w64 (from &quot;MinGW-builds&amp;quot;), with the aim of better interoperability with native Windows software. It includes: MSYS2-shell and MinGW-w64 Win32 shell &amp; MinGW-w64 Win64 shell. It supports &amp; can work with both 32bit &amp; 64bit multiple toolchains &amp; targets, (for 64bit a 64bit operating system is needed). MSYS2 is a successor of MSYS and MinGW-builds. MSYS2-shell uses &quot;pacman&amp;quot; for downloading packages, and these are GPG signed &amp; verified. Packages are by developer: lexx83 (Alexpux), mingwandroid, niXman. MSYS2 is a complete opensource development environment/shell solution/system. It can obtain related all toolchains &amp; packages from &quot;MinGW-builds&amp;quot; and MSYS2 repo, (and it also obtains related all dependency packages), for compiling/building other software. It can also obtain various tools &amp; language support &amp; compilers, like: perl, python, ruby, openssl, etc. A user has these options to choose from : by using MSYS2-shell &amp; MinGW-w64 Win64 shell, (option-A), either download Qt or QtCreator source from MSYS2 repo and compile/build, or (option-B), a user can get official Qt source or QtCreator source, and then compile/build using mingw-w64 toolchains obtained/available via MSYS2, from the windows Cmd-shell, or (option-C), a user can download pre-built binary files of Qt &amp; QtCreator (dynamic/shared built edition and/or static built edition) inside MSYS2 and run+use them instantly without compiling.

Some packages like MinGW-builds and TDM-GCC let you choose which exception implementation you want to use. You must ensure you use the same compiler used to build the Qt you use in order to avoid linker errors. If you choose to change the exception handling mechanism, you will need to rebuild all code, mostly because the libgcc shared library name is different between the exception handling settings.

From TDM-GCC readme:


&quot;GCC currently supports two methods of stack frame unwinding: Dwarf-2 (DW2) or<br />SJLJ (setjmp/longjmp). Until recently, only SJLJ has been available for the<br />Windows platform. This affects you, the end user, primarily in programs that<br />throw and catch exceptions. Programs which utilize the DW2 unwind method<br />generally execute more quickly than programs which utilize the SJLJ method,<br />because the DW2 method incurs no runtime overhead until an exception is thrown.<br />However, the DW2 method does incur a size penalty on code that must handle<br />exceptions, and more importantly the DW2 method cannot yet unwind (pass<br />exceptions) through &quot;foreign&amp;quot; stack frames: stack frames compiled by another<br />non-DW2-enabled compiler, such as OS DLLs in a Windows callback.

This means that you should in general choose the SJLJ version of the TDM-GCC<br />builds unless you know you need faster exception-aware programs and can be<br />certain you will never throw an exception through a foreign stack area.

As distributed, the SJLJ and DW2 packages of TDM-GCC can coexist peacefully<br />extracted to the same directory (i.e. any files in common are for all intents<br />and purposes identical), because the driver executables (the ones in the &quot;bin&amp;quot;<br />directory) are suffixed with &quot;-dw2&amp;quot; for the DW2 build, and the libraries and<br />other executables hide in another &quot;-dw2&amp;quot; directory in &quot;lib(exec)/gcc/mingw32&amp;quot;.<br />This allows you to use the same single addition to your PATH, and use DW2<br />exceptions only when you need them by calling &quot;gcc-dw2&amp;quot;, etc. If you truly want<br />DW2 exceptions as the default when calling &quot;gcc&amp;quot; (from Makefiles or configury<br />systems, for example), you can rename or copy the suffixed executables to their<br />original names.&quot;

I suggest to merge the (important) content from here with the article on MinGW. Please feel free to help out.

MinGW-64-bit

This is about MinGW-w64, MinGW, MSYS, MSYS2 and Qt 5.

Executive Summary

We recommend a MinGW-w64 based distribution with a recent gcc. Starting with Qt 5.0.1 there are also binary installers that ship a Mingw-w64 based toolchain + pre-built Qt libraries. The MinGW-builds repo includes MinGW-w64 toolchains.

Recommended package for 32 bit (also tested in CI system + used by installer for 5.1):
http://sourceforge.net/projects/mingwbuilds/files/host-windows/releases/4.8.1/32-bit/threads-posix/dwarf/x32-4.8.1-release-posix-dwarf-rev5.7z/download

Recommended package for 64 bit:
http://sourceforge.net/projects/mingwbuilds/files/host-windows/releases/4.8.1/64-bit/threads-posix/seh/x64-4.8.1-release-posix-seh-rev5.7z/download

Community member George Edison has cross-compiled Qt 5.0.1 for Windows using the Mingw-w64 compilers and is hosting the archives here:
http://files.quickmediasolutions.com/qt5/

Background

The MinGW from http://www.mingw.org/ does only support gcc 32 bit (host and target). The independent minGW-w64 project provides support for 64 bit, and also supports a much larger part of the Windows API. The MinGW-w64 project however does not provide official binary builds: These can be grabbed either from the personal build directories of the developers (the most popular being rubenvb), or from associated but independent projects like tdm-gcc or mingw-builds or msys2.

RubenVB personal builds

"RubenVB personal builds": For "32-bit Windows target":http://sourceforge.net/projects/mingw-w64/files/Toolchains targetting Win32/Personal Builds/rubenvb/ and "for 64-bit Windows target":http://sourceforge.net/projects/mingw-w64/files/Toolchains targetting Win64/Personal Builds/rubenvb/ :
Features different packages with cygwin, win32, win64, linux as host. Target is either win32 or win64. Packages are built with every GCC release, experimental and prerelease packages are built on request.

MinGW-builds

"MinGW-builds": http://sourceforge.net/projects/mingwbuilds/ : a binary package by developer: niXman, lexx83 (Alexpux). Provides both packages with a 32-bit and a 64-bit compiler (Windows host), that can also cross-compile to 32-bit or 64-bit. Packages are available with both "posix" and "win32" threading libraries, for 32 bit also with sjlj or dwarf exception variants. See also MSYS2.

MSYS2

"MSYS2": http://sourceforge.net/projects/msys2/ : MSYS2 (Minimal SYStem 2) is an independent rewrite of MSYS, a (command-line) shell for development usage, and based on modern Cygwin (POSIX compatibility layer) and MinGW-w64 (from "MinGW-builds"), with the aim of better interoperability with native Windows software. It includes: MSYS2-shell and MinGW-w64 Win32 shell & MinGW-w64 Win64 shell. It supports & can work with both 32bit & 64bit multiple toolchains & targets, (for 64bit a 64bit operating system is needed). MSYS2 is a successor of MSYS and MinGW-builds. MSYS2-shell uses "pacman" for downloading packages, and these are GPG signed & verified. Packages are by developer: lexx83 (Alexpux), mingwandroid, niXman. MSYS2 is a complete opensource development environment/shell solution/system. It can obtain related all toolchains & packages from "MinGW-builds" and MSYS2 repo, (and it also obtains related all dependency packages), for compiling/building other software. It can also obtain various tools & language support & compilers, like: perl, python, ruby, openssl, etc. A user has these options to choose from : by using MSYS2-shell & MinGW-w64 Win64 shell, (option-A), either download Qt or QtCreator source from MSYS2 repo and compile/build, or (option-B), a user can get official Qt source or QtCreator source, and then compile/build using mingw-w64 toolchains obtained/available via MSYS2, from the windows Cmd-shell, or (option-C), a user can download pre-built binary files of Qt & QtCreator (dynamic/shared built edition and/or static built edition) inside MSYS2 and run+use them instantly without compiling.

Exception handling: SJLJ, DWARF, and SEH

Some packages like MinGW-builds and TDM-GCC let you choose which exception implementation you want to use. You must ensure you use the same compiler used to build the Qt you use in order to avoid linker errors. If you choose to change the exception handling mechanism, you will need to rebuild all code, mostly because the libgcc shared library name is different between the exception handling settings.

SJLJ (setjmp/longjmp):
* available for 32 bit and 64 bit
* not "zero-cost": even if an exception isn't thrown, it incurs a minor performance penalty (~15% in exception heavy code) but sometimes the penalty can be more significant: https://bugreports.qt.io/browse/QTBUG-29653
* allows exceptions to traverse through e.g. windows callbacks

DWARF (DW2, dwarf-2)
* available for 32 bit only
* no permanent runtime overhead
* needs whole call stack to be dwarf-enabled, which means exceptions cannot be thrown over e.g. Windows system DLLs.

SEH (zero overhead exception)
* will be available for 64-bit GCC 4.8.
* rubenvb release is "available":http://sourceforge.net/projects/mingw-w64/files/Toolchains targetting Win64/Personal Builds/rubenvb/gcc-4.8-release/x86_64-w64-mingw32-gcc-4.8.0-win64_rubenvb.7z/download
* MinGW-builds release is "available":https://sourceforge.net/projects/mingwbuilds/files/host-windows/releases/4.8.1/64-bit/

From TDM-GCC readme:

"GCC currently supports two methods of stack frame unwinding: Dwarf-2 (DW2) or
SJLJ (setjmp/longjmp). Until recently, only SJLJ has been available for the
Windows platform. This affects you, the end user, primarily in programs that
throw and catch exceptions. Programs which utilize the DW2 unwind method
generally execute more quickly than programs which utilize the SJLJ method,
because the DW2 method incurs no runtime overhead until an exception is thrown.
However, the DW2 method does incur a size penalty on code that must handle
exceptions, and more importantly the DW2 method cannot yet unwind (pass
exceptions) through "foreign" stack frames: stack frames compiled by another
non-DW2-enabled compiler, such as OS DLLs in a Windows callback.

This means that you should in general choose the SJLJ version of the TDM-GCC
builds unless you know you need faster exception-aware programs and can be
certain you will never throw an exception through a foreign stack area.

As distributed, the SJLJ and DW2 packages of TDM-GCC can coexist peacefully
extracted to the same directory (i.e. any files in common are for all intents
and purposes identical), because the driver executables (the ones in the "bin"
directory) are suffixed with "-dw2" for the DW2 build, and the libraries and
other executables hide in another "-dw2" directory in "lib(exec)/gcc/mingw32".
This allows you to use the same single addition to your PATH, and use DW2
exceptions only when you need them by calling "gcc-dw2", etc. If you truly want
DW2 exceptions as the default when calling "gcc" (from Makefiles or configury
systems, for example), you can rename or copy the suffixed executables to their
original names."

DW2 Issues

  • If a library that uses DW2 exception handling (e.g. libgcc_s_dw2-1.dll) is loaded using LoadLibrary and FreeLibrary is not called, the program will crash. See http://comments.gmane.org/gmane.comp.gnu.mingw.user/41724
  • Calling FreeLibrary to unload a dll that links to both dynamic libgcc_s_dw2 and a library that links to static libgcc_s_dw2 results in a crash

GCC Threading model (posix vs win32)

Mingw-Builds (and the experimental rubenvb packages) also let you choose between the threading model internally used by (lib)gcc:

  • posix (built upon MinGW-w64's winpthreads)
    • "an implementation of POSIX threads for win32 is also available under the experimental directory. Its main goal is to support C+11 standard threading, which supports only using POSIX threads at the moment." http://mingw-w64.sourceforge.net/
      '
      enables C11 library features contained in the headers <thread>, <mutex>, and <future>.
      '
      Performance degradation in specific scenarios. C11 functionality is significantly slower than native Win32 implementation or even MSVS2012's implementation.


* win32
' uses native Win32 threading functions.
'
no C11 <thread>, <mutex>, or <future>
' best performance

h2. Criteria for original decision on toolchain
Following criteria for selecting the mingw package have been brought up on the mailing list . The comments about mingw-builds, rubenvb might not be up to date any more.
* Ease of installation
' rubenvb: different packages (host x target etc) can be confusing. no additional configuration needed when not cross-compiling.
'
mingw-builds: 32 bit binaries do not have prefix, but requires additions to configure / mkspecs (to switch to 64 bit target)
* Stability/Quality
' mingw-builds: no issues in latest packages
'
rubenvb: no issues in latest packages
* most recent compilers (GCC 4.7 preferably, GCC 4.6 if not)

'
rubenvb: GCC 4.7.2 (and GCC 4.8 prerelease in unstable) and a "32-bit Clang 3.2":http://sourceforge.net/projects/mingw-w64/files/Toolchains targetting Win32/Personal Builds/rubenvb/clang-3.2-release/
* working' GDB and tested with Creator (with required Python support)
'
mingw-builds: 7.5.1
' rubenvb: 7.5
* large file support (aka _FILE_OFFSET_BITS=64)
'
mingw-builds: yes (_FILE_OFFSET_BITS in headers, also e.g. lseek64 symbol defined)
' rubenvb: yes (_FILE_OFFSET_BITS in headers, also e.g. lseek64 symbol defined)
* threading
'
mingw-builds: gcc -v says 'posix' or 'win32' depending on which build you download
' rubenvb: gcc -v says 'win32' . std::thread support in "experimental package":http://sourceforge.net/projects/mingw-w64/files/Toolchains targetting Win64/Personal Builds/rubenvb/gcc-4.7-experimental-stdthread//Personal Builds/rubenvb/gcc-4.7-experimental-stdthread/
* zero-overhead exceptions (no SJLJ exceptions)
'
rubenvb: 32-bit GCC dw2 builds provided, and GCC 4.8 prerelease is 64-bit seh.
' mingw-builds: 32-bit GCC dw2 builds provided, and GCC 4.8 prerelease is 64-bit seh.
* standard win32 headers, if possible using the Platform SDK headers
'
rubenvb: Win32 API, DirectX (from WINE project), and DDK (from ReactOS project)
' mingw-builds: Win32 API, DirectX (from WINE project) and DDK (from ReactOS project)
* large set of included libraries
'
rubenvb: none, only Win32 and GCC libraries provided.

rubenv: 64 bit or 32 bit are seperate packages
' mingw-builds: both 32 bit and 64 bit host, 32 bit and 64 bit target
* make with -j support
'
rubenvb: -j seems to work
' mingw-builds: -j seems to work
'
NOTE: Qt's own "jom" tool can be used to build Qt and CMake "MinGW Makefiles" with much better performance than mingw32-make

h3. Building Qt


* Note: If you are using the Qt 5 source .tar.gz, you need to do the following for configure.exe to build properly:
' Start a Windows command prompt (Cmd-shell)

<br />cd C:5_src<br />if not exist qtbaseitignore type nul>qtbaseitignore<br />


* Start a Windows command prompt (Cmd-shell), and run/execute below commands:

<br />cd C:5_src<br />set INCLUDE=C:5_deps\icu\dist\include;C:5_deps\openssl-1.0.1e\dist\include<br />set LIB=C:5_deps\icu\dist\lib;C:5_deps\openssl-1.0.1e\dist\lib<br />set QMAKESPEC=<br />set QTDIR=<br />


If you have downloaded perl, ruby, python separately from their official websites & installed in separate folders, then adjust & execute/run below command:

<br />cd C:5_src<br />set PATH=&amp;#37;CD&amp;amp;#37;;&amp;#37;CD&amp;amp;#37;32\bin;C:64-4.8.2\bin;C:;C:27;C:193\bin;C:5_deps\icu\dist\lib;C:5_deps\openssl-1.0.1e\dist\bin;C:Files (x86);&amp;#37;SystemRoot&amp;amp;#37;32<br />

Do not use both, (unless you know what you are doing).<br />'''''' If you are going to use MSYS: extract or install MSYS into C:directory<br />'''''' If you are going to use MSYS2: extract or install MSYS2 into C:2 directory<br />* Prepare MSYS or MSYS2 for development environment: pre-install build related required dependencies &amp; components.<br />'''''' See inside MinGW-builds section (in above), on how you can prepare MSYS or [[MSYS2]] for building/compiling.<br />* Run MSYS (or MSYS2)<br />* run git checkout scripts:<br />


mkdir -p /c/QtSDK
cd /c/QtSDK
git clone https://github.com/Alexpux/Qt-builds.git Qt-build

<br />h3. Building Qt
<br />Now scripts provide building '''Qt-4.8.4''', '''Qt-5.0.0''', '''Qt-5.0.1''', '''Qt-5.0.2''', '''Qt5 from git''' with latest release of QtCreator, qbs(from git). Buildinq Qt is simple by run:<br />


./buildall <x32|x64> —qt-version=<version>

<br />For example,<br />


./buildall x32 —qt-version=5.0.0

<br />build 32-bit Qt-5.0.0 with QtCreator-2.7.0 and install them into C:/QtSDK/Qt32-5.0.0, Qt dependencies and prerequisites will be installed into C:/QtSDK/ported32.
<br />For building Qt5 from git you need specify branch what you want to build. If you don't specify branch then by default building stable branch.<br />


./buildall x32 —qt-version=git —qt-git-branch=stable

<br />This command download qt5 from git stable branch and try to build 32-bit version of Qt5.
<br />'''Note:''' If you want to move Qt directory elsewhere than after moving you need to execute from QTDIR:<br />


qtbinpatcher —nobackups

<br />'''Other useful options are:'''<br />


—opengl-desktop
Use option "-opengl desktop" instead of "-angle" during configure Qt5 sources.
—no-qtcreator
Tell build script to exclude Qt-Creator from building.
—qtquickcontrols
Tell build script to build qtquickcontrols.
—static-qt
Build Qt as static libraries. Qt5 now has many issues with static build and now I possible to build it without Webkit, ANGLE, ICU.
—extra-stuff
Build some 3rdparty apps (poppler, cmake) with dependencies


Notes: Do not use (or try to avoid using) different type of toolchains for building different sub-components for the same/main project, when targeted for same platform/OS. If you are using MinGW-w64 based toolchains from MSYS2\mingw32 or MSYS2\mingw64, then for all sub-components build and for main project build, use same MSYS2 toolchains. If you are using MinGW toolchain, then for all of your sub-components & main project build, use same MinGW toolchain. If you are using MinGW-w64 toolchains from "MinGW-builds", then for all sub-components and for main project build, use same MinGW-builds toolchains.
