Compiling using MingGW-w64 for both 32-bit and 64-bit

Back to Compiling in Windows

1. Installing Minimalist GNU for Windows-w64 (MinGW-w64)

The objective will be to try to use the MingGW-w64 toolchain instead of the standard MingW since it has support for both 32-bit and 64-bit compiling. Note: We are not successful yet, but just writing down our steps as we go along.

Details of the prefixes of files can be found at ​What to download

MingW-w64 site is ​http://mingw-w64.sourceforge.net

If you are on 64-bit Windows download one of the binary packages from ​http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Automated%20Builds/ with name starting with mingw-w64-1.0-bin_i686-mingw_

If you are on 32-bit Windows download one of the binary packages from ​http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/ with name starting with mingw-w32-1.0-bin_i686-mingw_

Extract your respective zip into a folder called C:\mingw-w64

2. Installing Msys =

MSys is 32-bit but you can use it with your 32-bit or 64-bit mingw-w64. Instructions are here ​mingw-w64 with MSYS and repeated here for completeness

• download ​Msys MSYS-20110309.zip
• Extract into a folder called C:\Msys
• launch msys.bat
• type

sh /postinstall/pi.sh

When prompted type in the path where you extracted your mingw
