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 in System Control Panel Advanced Settings — 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 or C:/mingw_w32/mingw depending on which tool chain you chose 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

(THIS WE DON'T THINK IS NECESSARY ANYMORE and we didn't do it)

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;

We don't think this is necessary either If you get errors about g++ and libstdc++ moved try this If you are runnning gcc 4.4.0+ and you get complaints about link g++ you probably need to do this too. Changing file: mingw*\i686-w64-mingw32\lib32\libstdc++.la 

library_names='libstdc++.dll.a'

to 

#library_names='libstdc++.dll.a' 
library_names='libstdc++.a'

#this currently fails at linker phase with a whole bunch of 

simplify/.libs/libsimplify.a(TopologyPreservingSimplifier.o):TopologyPreservingS
implifier.cpp:(.rdata+0x1f0): undefined reference to `geos::geom::util::GeometryTransformer::transformGeometryCollection(geos::geom::GeometryCollection const*,
geos::geom::Geometry const*)'

and bunch of other classes in util::GeometryTransformer..
the .la file gets created so seems to be at linker phase.

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

5. Compiling Proj

Download Proj4 from the web site, and the datum shifts grid file.

and copy to c:\projects\proj The datum grid file must be unzipped into the "nad" subdirectory of the Proj4 source tree. 

 cd /c/projects/proj
 tar xvfz proj-4.6.1.tar.gz
 cd proj-4.6.1
 cd nad
 unzip ../../proj-datumgrid-1.5.zip
 cd ..
 ./configure --prefix=/c/projects/proj/rel-4.7.0 --build=i686-w64-mingw32 --host=i686-w64-mingw32 --target=i686-w64-mingw32 --enable-shared --disable-static
 make
 make install
