Compiling PostGIS 2.0 using MingGW-w64 for 64-bit

Back to Compiling in Windows If you want to get to the last step fast of just compiling PostGIS without having to compile the dependencies, you can download our prepared mingw64 bit chains from and for 32-bit (for PostgreSQL 9.2+) , extract to C:\ming64 and C:\ming32, and launch the corresponding c:\ming64\msys\msys.bat and you should be on your way

and edit the file in C:\ming64\projects\postgis\builds\

for testing you'll want to initdb the postgres servers in C:\ming64\projects\pgx64 and then run the start stop scripts. Clicking the batch will start the postgres server and clicking enter will shut it down. With that you can jump straight to the section on compiling PostGIS

For PostgreSQL 9.2 and above, you can also use more or less the same steps and that is what we use to package the 32-bit PostgreSQL 9.2+. We'll be publishing our ming32 tar ball soon. Also there are issues with GEOS compile about 4.5.4 or so, in 4.6.1+, the make check crashes and so does PostGIS tests when compiled with GCC 4.6+. That said you should pick a build lower than GCC 4.6. Issues are documented in (also similar issue compiling Geso under windows 64-bit SDK )

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.

Details of the prefixes of files can be found at What to download

MingW-w64 site is

starting with mingw-w64-1.0-bin_i686-mingw_

mingw-w32-1.0-bin_i686-mingw_ (for my purposes I used and for native 64-bit (currently using mingw-w64-1.0-bin_i686-mingw_20110516)

  • Note if you are on 64-bit windows you can compile for both 32-bit and 64-bit by downloading both.
  • Extract your respective zip into a folder called C:\ming64\mingw64 or c:\ming32\mingw32

GEOS fails to link if it picks up 32-bit dlls so to overcome this, I copied over the dlls from windows/sytem32 and renamed them as described in #linking errors seems to be caused by as described here mingw64 is picking up the 32-bit dlls from syswow64 instead of the 64-bit dlss from windows/system32 I only needed to copy ws2_32.dll for GEOS to compile without errors Others may be needed not sure. with windows explorer copy the files from windows/system32


GEOS also gives missing vtable message during link. I think this was caused by msys missing find.exe, so I copied the find.exe from regular msys packaged as instructed in the above link. To your folder: C:\ming64\x86_64-w64-mingw32\lib and then rename them adding a lib extensions so you have

# these ones didn't seem necessary for PostGIS: libmsimg32.dll,libgdi32.dll, libcrypt32.dll and libwldap32.dll

prefixed files

These sometimes exist only with the prefixes and cause issues during compilation so you'll need prefixless versions

cp /mingw/bin/x86_64-w64-mingw32-cpp.exe /mingw/bin/cpp.exe
cp /mingw/bin/x86_64-w64-mingw32-strip.exe /mingw/bin/strip.exe

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 (update there is now a newer MSYS --
  • Extract into a folder called C:\Msys
  • launch msys.bat
  • type
sh /postinstall/

When prompted type in C:/ming64/mingw64 or C:/ming32/mingw32 depending on which tool chain you chose Once done, type logout and the console should exit.

3a. Installing Autoconf, Automake and Libtool

Relaunch C:\mysy\msys.bat

export PROJECTS=/c/ming64/projects

Verify which versions of these you have with

autoconf --version


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

tar -xvf autoconf-2.65.tar.gz
cd autoconf-2.65
./configure --host=x86_64-w64-mingw32 --prefix=/mingw  (if you are building for 32-bit then use --host=i686-w64-mingw32)
make && make install
autoconf --version

repeat same exercise for automake

For libtool

tar -xvf libtool-2.4.10.tar.gz 

cd libtool-2.4.10
./configure --host=x86_64-w64-mingw32 --disable-shared --prefix=/mingw
#if you are building on 32-bit then use --host=i686-w64-mingw32 for the host
#if you get a message that gcc is not usable, then you probably set your
# mingw setting wrong or did not install automake/autotools in /mingw
#try to fix by rerunning the sh /postinstall/ again
make clean && make && make install
libtool --version

3.b create project folders

 export PROJECTS=/c/ming64/projects
 mkdir pg
 mkdir postgresql
 mkdir geos
 mkdir proj
 mkdir docbook


export GDAL_VER=1.9.1
cd ${PROJECTS}/gdal
tar xvfz gdal-1.9.1.tar.gz
cd gdal-${GDAL_VER}
./configure --host=x86_64-w64-mingw32 --build=x86_64-w64-mingw32 --with-threads=no --prefix=${PROJECTS}/gdal/rel-${GDAL_VER}w64 
make && make install
cd ${PROJECTS}/gdal/rel-${GDAL_VER}w64/bin
strip *.dll


cd ${PROJECTS}/docbook Download the latest Docbook from into that folder and untar.

Extract somewhere. In this case I chose my projects folder. You'll need to set this folder for the --with-xsldir setting

You should have a folder now docbook/docbook-xsl-1.76.1 or something similar

4. Compiling GEOS

Download latest GEOS source from either the You can also use the trunk svn version If you are using svn version, make sure to run:


this fails at linker phase with a whole bunch of errors if you compile without doing #linking errors seems to be caused by as described here mingw64 is picking up the 32-bit dlls from syswow64 instead of the 64-bit dlss from windows/system32 I may have over-copied, but to remedy before evening starting configure with windows explorer copy the files from windows/system32

ws2_32.dll, kernel32.dll, advapi32.dll, mscvrt.dll, user32.dll

To your folder: C:\mingw\mingw64\x86_64-w64-mingw32\lib and then rename them adding a lib extensions so you have

libws2_32.dll, libkernel32.dll, libadvapi32.dll, libmscvrt.dll, libuser32.dll

# hack described in

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.

-- follow instructions in

export GEOS_VER=3.3.5
cd ${PROJECTS}/geos
tar xjf geos-${GEOS_VER}.tar.bz2
cd geos-${GEOS_VER}
./configure --host=x86_64-w64-mingw32 --prefix=${PROJECTS}/geos/rel-${GEOS_VER}w64 | tee /c/geos_configure_3.3.log 
make install

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

strip ${PROJECTS}/bin/geos/rel-${GEOS_VER}w64/*.dll

Installing LibIconv

For iconv we are going to compile our own copy instead of installing from GNUWin.

Save the source in your C:\ming64\projects directory. Open up the MSYS terminal. Ignore the errors in the configure process.

tar xvfz libiconv-1.13.1.tar.gz
cd libiconv-1.13.1
./configure --host=x86_64-w64-mingw32 --build=x86_64-w64-mingw32 --target=x86_64-w64-mingw32 --prefix=${PROJECTS}/rel-libiconv-1.13.1w64
make install

Copy rel-.. contents int c:\mingw\mingw64 folder. For some reason using libiconv-prefix did not work for configuring postgis. Verify if the version of iconv you are running is the same as the one you just compiled (1.13):

# iconv --version

Compiling Proj

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

and copy to c:\ming64\projects\proj The datum grid file must be unzipped into the "nad" subdirectory of the Proj4 source tree.

 #set this to whereever you plan to keep your source
 #I have one for 32-bit and one for 64-bit
 export PROJECTS=/c/ming64/projects   
 cd ${PROJECTS}/proj
 tar xvfz proj-4.8.0.tar.gz
 cd proj-4.8.0
 cd nad
 unzip ../../
 cd ..
 ./configure --prefix=${PROJECTS}/proj/rel-4.8.0w64 --host=x86_64-w64-mingw32 --enable-shared
 make clean
 make && make install

Compiling and Installing C-Unit

Download from into c:\projects

tar -xvf CUnit-2.1-2-src.tar.bz2
cd CUnit-2.1-2
#if you are building for 64-bit then use x86_64-w64-mingw32 for the build,host,target
#32 bit uses i686-w64-mingw32 for build, host, target
./configure --host=x86_64-w64-mingw32 --prefix=/mingw
make && make install

For some reason, PostGIS couldn't find my cunit install. So I had to copy the files: from C:\ming64\mingw64\include\CUnit to C:\ming64\mingw64\x86_64-w64-mingw32\include\CUnit

7. Compiling LibXML2

mkdir ${PROJECTS}/libxml
cd ${PROJECTS}/libxml
 tar xvfz libxml2-2.7.8.tar.gz 
cd libxml2-2.7.8
#if you are building for 64-bit then use x86_64-w64-mingw32 for the build,host,target
#32 bit uses i686-w64-mingw32 for build, host, target
 ./configure --prefix=/c/projects/libxml/rel-libxml2-2.7.8w64 --build=x86_64-w64-mingw32 --host=x86_64-w64-mingw32 --target=x86_64-w64-mingw32 --enable-shared --with-threads=no  CFLAGS=-O2
#Note to self: used to have CCFLAGS=LDFLAGS="-Wl,-static"  in here will see how it goes without
#If you have pthreads installed, libxml picks it up and royally screws up thus the need for --with-threads=no
 make install

You might get an error during the configure process

/bin/rm: cannot lstat `libtoolT': No such file or directory

That error seems safe to ignore.

8. Compiling PostgreSQL 9.1

Download source from:

mkdir ${PROJECTS}/pgx64
cd postgresql
tar -xvjf postgresql-9.1.3.tar.bz2
cd postgresql-9.1.3
#if you are building for 64-bit then use x86_64-w64-mingw32 for the build,host,target
#32 bit uses i686-w64-mingw32 for build, host, target
#EnterpriseDb VC++ 64-bit builds are compiled with disable float8 by val. 
#If we don't include this line, the modules compiled against mingw64 will be incompatible with edb builds
./configure --prefix=${PROJECTS}/pgx64/pg91 \
 --build=x86_64-w64-mingw32 \
 --host=x86_64-w64-mingw32 --target=x86_64-w64-mingw32 \
 --with-pgport=5441 --enable-cassert --enable-debug \
 --enable-integer-datetimes --disable-float8-byval --without-zlib

 make install
#initialize the database cluster
/c/projects/pgx64/pg91/bin/initdb -U postgres -D ${PROJECTS}/pgx64/pg91/data -A trust

Compiling JSON-C

This is needed if you want ST_GeomFromGeoJSON to be functional. Download and save to c:\ming64\projects\json-c

cd ${PROJECTS}/json-c
tar xvfz json-c-0.9.tar.gz
cd json-c-0.9
## had to compile with -w (disable warnings otherwise it gave errors)
## if using 32-bit (ming32), use i686-w64-mingw32 for host/build
./configure --build=x86_64-w64-mingw32 \
 --host=x86_64-w64-mingw32 --target=x86_64-w64-mingw32 \
 --prefix=/c/projects/json-c/rel-0.9w64 CFLAGS=-w
make clean
make install

Copy over needed dlls to PostgreSQL folders

export PATH=$PATH:/c/projects/pgx64/pg91edb/bin:/mingw
export PGHOST=localhost
export PGPORT=5441
export PGUSER=postgres
cp /c/projects/geos/rel-3.3.3w64/bin/*.dll /c/projects/pgx64/pg91edb/bin
cp /c/projects/gdal/rel-1.9.0w64/bin/*.dll /c/projects/pgx64/pg91edb/bin
cp /c/projects/proj/rel-4.7.0w64/bin/*.dll  /c/projects/pgx64/pg91edb/bin
cp /c/mingw/mingw64/bin/libgcc_s_sjlj-1.dll /c/projects/pgx64/pg91edb/bin
cp /c/projects/geos/rel-3.3.3w64/bin/*.dll /c/projects/pgx64/pg91/bin
cp /c/projects/gdal/rel-1.9.0w64/bin/*.dll /c/projects/pgx64/pg91/bin
cp /c/projects/proj/rel-4.7.0w64/bin/*.dll  /c/projects/pgx64/pg91/bin
cp /c/mingw/mingw64/bin/libgcc_s_sjlj-1.dll /c/projects/pgx64/pg91/bin

Getting GTK

If you want to build the shp2pgsql-gui loader in 64-bit, you can use the pre-compiled gtk bundle which already has the needed headers

export PORJECTS=/c/ming64/projects/gtk
mkdir gtk
cd gtk

Compiling PostGIS 2.0

HACK only needed for PostGIS 2.0.3 and below (also not an issue if compiling 1.5 branche) (fixed in branch/2.0 and trunk already)

  • There is a problem at least for my Mingw64 that prevents functions like ST_AsText and ST_AsKML that makes it leave out digits randomly
  • This also causes issues for shp2pgsql. The issue is the fact that the MingW64 chain uses
  • Microsoft's vsprintf version instead of the C99 one. This version when space is not enough returns an error code instead of length of output the write
  • To work around this issue, I put in this pretty ugly hack in the liblwgeom/string_buffer.c around line 210


	if ( len < 0 ) 
		return len;


	if ( len < 0 ) 
		len = _vscprintf(fmt, ap2); 

Details of this issue are outlined in #1668

Before you'll be able to make check, you'll need your postgresql instance launched and the following files copied into the bin folder: After you are done, make sure to copy the following files to your PostgreSQL bin folder:

From your geos../bin  *.dll
From your gdal../bin *.dll
FROM mingw64 (or mingw32) bin - libiconv-2.dll, libgcc_s_sjlj-1.dll, libstdc++-6.dll
From libxml/bin compile  *.dll
From gdal/bin  libgdal-1.dll (you'll also need zlib1.dll which you can copy from EDB install or download binary for)
From proj/bin  -- libproj-0.dll

#this part is a hack, but again didn't work without it #you can try without doing this, but if you get errors about # conflicting type def boolean during PostGIS compile, you need this. #In my case I got this:

In file included from c:/ming64/projects/json-c/rel-0.9w64/include/json/json_util.h:1

                 from c:/projects/json-c/rel-0.9w64/include/json/json.h:23,
                 from lwgeom_in_geojson.c:31:
c:/ming64/projects/json-c/rel-0.9w64/include/json/json_object.h:32: error: conflictin
types for 'boolean'
mingw32/include/rpcndr.h:52: note: previous declaration of 'boolean' was here
make[1]: *** [lwgeom_in_geojson.o] Error 1
  • Open up /c/projects/json-c/rel-0.9/include/json/json_object.h
  • remark out line 32 that reads

typedef int boolean

  • so it should now read

/** typedef int boolean; **/

  • During the PostGIS configure process, you have to put this back the way it was otherwise configure complains json.h or something is not usable and refuses to configure with JSON-C support. Then you remark the line out again during compile. Crazy I know, but json-c won't compile without that line so can't take it out before json-c compile.

If you run into problems with your build, pipe the output into a file for further analysis. The GUI requires that pkg-config be on your PATH, check that it is there by running 'which pkg-config'.

make 2>&1 | tee /c/build.log
make check
make install
