There are four commands to update: GCC Assembler, GCC C++ Assembler, GCC C Compiler, and MinGW C++ Linker. For example, change it to C:\MinGW_w64\bin.
#Mingw 64 update#
Update the path variable according to your MinGW w64 installation.

This is probably the best way to use Windows 64-bit to generate 64-bit applications. In summary, from the link provided above, it is best if you go to the 'Personal Builds' section and download the latest sezero build. It will save you a lot of time and you will not encounter some naming troubles in later steps. As sezero build has a conventional directory structures and file names (same as MinGW 32-bit), I recommend using the sezero build. Technically, the automated build performs cross-compilation, while the sezero build performs native compilation. For example, the sezero build I used (mingw-w64-bin_x86_64-mingw_20101003_sezero) is 64-bit binary producing 64-bit application, while a binary from the automated build (mingw-w64-1.0-bin_i686-mingw_20101129) is 32-bit binary generating 64-bit application. There are some significant different for personal and automated builds (as of Dec 2010). You can choose your preferred version from here. Although our target platform is Windows 64-bit, the compiler may be a 32-bit application that performs cross-compilation for you. Get CompilerThe first task is to obtain a proper MinGW w64 compiler. The following parts of this tutorial assume that you already installed Eclipse and MinGW 64-bit at your preferred paths and will only discuss how you can change Eclipse settings to build and run your applications.

This tutorial is based on 64-bit MinGW (probably version 4.5-the version is not clear from the download page) and Eclipse Galieo (SR2 Build ID:2010 02 18-1602) and Eclipse Helios (SR1 for Windows 64 bit, eclipse-cpp-helios-SR1-win32-x86_64).

This tutorial discusses how you can use MinGW 64-bit and Eclipse to build an application.
