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

starting with mingw-w64-1.0-bin_i686-mingw_

mingw-w32-1.0-bin_i686-mingw_ (for my purposes I used mingw-w32-1.0-bin_i686-mingw_20110408.zip)

  • Extract your respective zip into a folder called C:\mingw_w64 or c:\mingw_w32
  • Add c:\mingw_w64\bin (or c:\mingw_w32\bin) to your windows environment path variable e.g. 

set PATH=c:\mingw_w32\bin;%PATH%

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 C:/mingw_w64/mingw Once done, type logout and the console should exit.

3. Installing Autoconf, Automake and Libtool

Relaunch C:\mysy\msys.bat

Verify which versions of these you have with

autoconf —version etc.

If they are not newer (or you get not found) than below then download and install. Download the source code from the GNU site and save to c:\projects 

cd /c/projects
tar -xvf autoconf-2.65.tar.gz
cd autoconf-2.65
./configure --build=i686-w64-mingw32 --host=i686-w64-mingw32 (if you are building for 64-bit then use --build=x86_64-w64-mingw32)
make && make install
autoconf --version

repeat same exercise for automake

For libtool 

cd /c/projects
tar -xvf libtool-2.4.10.tar.gz
cd libtool-2.4
./configure --build=i686-w64-mingw32 --host=i686-w64-mingw32 --target=i686-w64-mingw32  --disable-shared 
#if you are building for 64-bit then use --host=x86_64-w64-mingw32 for the build,host,target
make clean && make && make install
libtool --version

4. Compiling GEOS

Download latest GEOS source from ​http://trac.osgeo.org/geos/ either the ​http://download.osgeo.org/geos/geos-3.3.0.tar.bz2 or ​http://download.osgeo.org/geos/geos-svn.tar.bz2 and copy to c:\projects\geos. You can also use the trunk svn version ​https://svn.osgeo.org/geos/trunk. If you are using svn version, make sure to run: 

sh autogen.sh

I had to comment out the lines as seen below, lines 159 and 166 in your mingw*\include\c++\4.4.6\cwchar 

  //using ::swprintf;  
  //using ::vswprintf;

cd /c/projects/geos
bzip2 -d -c geos-svn.tar.bz2 | tar xvf -
./configure --prefix=/c/projects/geos/rel-3.3.0 --build=i686-w64-mingw32 --host=i686-w64-mingw32 --target=i686-w64-mingw32
make
make install

To strip all the debug info weight from the libgeos DLL files, run 

# strip /c/projects/bin/geos/rel-3.3.0/*.dll
