= Building on Windows with CMake and mingw64 chain =
*** this is still a work in progress **

You can use the regular CMake 32-bit binaries to build 64-bit and just extract somewhere:
http://cmake.org/cmake/resources/software.html (I used the zip file http://www.cmake.org/files/v2.8/cmake-2.8.10-win32-x86.zip and extracted to folder
 latest now is http://www.cmake.org/files/v2.8/cmake-2.8.11-win32-x86.zip which should work fine and probably better and just extracted  into folder C:\ming64\cmake-2.8.10.2-win32-x86 )


== Configure ==

Building from SVN development branch requires to generate the `geos_svn_revision.h` file with POSIX shell script:

{{{
tools\svn_repo_revision.sh
}}}

## NOTE: for this I had to use some suggestions 
## from http://osgeo-org.1560.x6.nabble.com/Compiling-geos-with-mingw64-td5034567.html which are not committed yet
## I was also using the mingw64 pre-compiled build - http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/rubenvb/gcc-4.8-release/
( x86_64-w64-mingw32-gcc-4.8.0-win64_rubenvb.7z )

export PATH=".:/bin:/include:/mingw/bin:/mingw/include:/c/Windows/system32:/c/Windows:/usr/local/bin:/c/ming64/cmake-2.8.10.2-win32-x86/bin"

Output of tests should look something like
