Toolchains used in Qt binary packages Qt Version For Qt 5, a newer MinGW-w64 toolchain is actually required. Newer Qt 4.8 binary packages ship with a mingw-w64 based toolchain.

Up to Qt 4.8.6, Qt 4 ones are built with a toolchain using gcc 4.4. There are binary installers targetting MinGW for both Qt 4 and Qt 5. The MinGW-w64 project does host several different binary packages, done by different people. By now it also supports a much larger part of the Win32 API.
#Mingw compiler 64 Bit#
MinGW-w64 is a fork with the original aim to also support generation of 64 bit binaries.
