PostgreSQL for Windows can be built using MinGW, a Unix-like build

environment for Microsoft operating systems.

The MinGW build procedure uses the normal build system described in

this chapter.

MinGW, the Unix-like build tools, and MSYS, a collection

of Unix tools required to run shell scripts

like <command>configure</command>, can be downloaded

from <ulink url="http://www.mingw.org/"></ulink>. Neither is

required to run the resulting binaries; they are needed only for

creating the binaries.

To build 64 bit binaries using MinGW, install the 64 bit tool set

from <ulink url="https://mingw-w64.org/"></ulink>, put its bin

directory in the <envar>PATH</envar>, and run

<command>configure</command> with the

<command>--host=x86_64-w64-mingw32</command> option.

After you have everything installed, it is suggested that you

to install any prerequisite packages.

<productname>Bison</productname> and <productname>Flex</productname> are

required. Only <productname>Bison</productname> versions 2.3 and later

Both <productname>Bison</productname> and <productname>Flex</productname>

You will need to add the directory containing

<filename>flex.exe</filename> and <filename>bison.exe</filename> to the

PATH environment variable. In the case of MinGW, the directory is the

<filename>\msys\1.0\bin</filename> subdirectory of your MinGW

installation directory.

The Bison distribution from GnuWin32 appears to have a bug that

causes Bison to malfunction when installed in a directory with

spaces in the name, such as the default location on English

installations <filename>C:\Program Files\GnuWin32</filename>.

Consider installing into <filename>C:\GnuWin32</filename> or use the

NTFS short name path to GnuWin32 in your PATH environment setting

(e.g., <filename>C:\PROGRA~1\GnuWin32</filename>).
