This affects you, the end user, primarily in programs that Until recently, only SJLJ has been available for the "GCC currently supports two methods of stack frame unwinding: Dwarf-2 (DW2) or rubenvb release is available targetting Win64/Personal Builds/rubenvb/gcc-4.8-release/x86_64-w64-mingw32-gcc-4.8.0-win64_rubenvb.7z/download.needs whole call stack to be dwarf-enabled, which means exceptions cannot be thrown over e.g.allows exceptions to traverse through e.g.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:.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.

You must ensure you use the same compiler used to build the Qt you use in order to avoid linker errors. Some packages like MinGW-builds and TDM-GCC let you choose which exception implementation you want to use.
Mingw 64 bits download#
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. It can also obtain various tools & language support & compilers, like: perl, python, ruby, openssl, etc. 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. MSYS2 is a complete opensource development environment/shell solution/system.

Packages are by developer: lexx83 (Alexpux), mingwandroid, niXman. MSYS2-shell uses "pacman" for downloading packages, and these are GPG signed & verified. MSYS2 is a successor of MSYS and MinGW-builds. It supports & can work with both 32bit & 64bit multiple toolchains & targets, (for 64bit a 64bit operating system is needed). It includes: MSYS2-shell and MinGW-w64 Win32 shell & MinGW-w64 Win64 shell. "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.
Mingw 64 bits 32 bit#
Packages are available with both "posix" and "win32" threading libraries, for 32 bit also with sjlj or dwarf exception variants. 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. "MinGW-builds": : a binary package by developer: niXman, lexx83 (Alexpux). Packages are built with every GCC release, experimental and prerelease packages are built on request. "RubenVB personal builds": For 32-bit Windows target targetting Win32/Personal Builds/rubenvb/ and for 64-bit Windows target targetting Win64/Personal Builds/rubenvb/ :įeatures different packages with cygwin, win32, win64, linux as host. 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. The independent minGW-w64 project provides support for 64 bit, and also supports a much larger part of the Windows API.

The MinGW from does only support gcc 32 bit (host and target). Recommended package for 32 bit (also tested in CI system + used by installer for 5.1):Ĭommunity member George Edison has cross-compiled Qt 5.0.1 for Windows using the Mingw-w64 compilers and is hosting the archives here: The MinGW-builds repo includes MinGW-w64 toolchains. Starting with Qt 5.0.1 there are also binary installers that ship a Mingw-w64 based toolchain + pre-built Qt libraries. We recommend a MinGW-w64 based distribution with a recent gcc. This is about MinGW-w64, MinGW, MSYS, MSYS2 and Qt 5. 5 MinGW-builds (with OpenSSL, ICU and QtWebKit).4 Criteria for original decision on toolchain.3.5 GCC Threading model (posix vs win32).3.4 Exception handling: SJLJ, DWARF, and SEH.
