Compiling PostGIS 2.0 under Windows using MinGW/Msys

NOTE: This is still a work in progress - still needs lots of refinement ==

A step by step guide to compiling PostGIS in Windows. This guide assumes that you already have a PostgreSQL installation on your computer. You will have to compile PostgreSQL here too, but that is just for the process of compiling PostGIS.

Install Directories

We have used the following install directories:

MinGW: c:\MinGW
Msys: c:\msys
sources c:\projects
install directory for postgresql: c:\projects\pg\pg90 (where pg90 is whatever your respective version is of PostgresQL)

Useful Utilities

A good tool for extracting tar-files is 7-zip from ​http://www.7-zip.org

1. Installing Minimalist GNU for Windows (MinGW)

Download Automated MinGW Installer 5.1.4 version from ​here (Current version from ​http://sourceforge.net/project/showfiles.php?group_id=2435)

  1. Run the setup file and choose everything (except possibly Ada)
  2. Accept the default Install location of C:\MinGW

2. Installing Minimal System (MSYS)

MSYS provides you with a unix shell environment for compiling code under windows.

Download MSYS version 1.0.11. ​http://sourceforge.net/projects/mingw/files/MSYS%20Base%20System/msys-1.0.11/MSYS-1.0.11.exe/download (this is listed in ​http://sourceforge.net/project/showfiles.php?group_id=2435)

  1. Say y to post Installation
  2. When prompted do you have MinGW -> y
  3. When prompted for where it is type -> C:\MinGW

3. Installing Mys Development Toolkit

Download the MysDTK1.0.1 from ​http://downloads.sourceforge.net/mingw/msysDTK-1.0.1.exe

  1. Run the EXE install and accept all the defaults

4. Installing GNUWin Support Packages

Download and install the following from ​http://gnuwin32.sourceforge.net/packages.html. Run each file and be sure to change the install directory to c:\MinGW

5. Update m4

  1. download from: ​http://prdownloads.sourceforge.net/mingw/m4-1.4.7-MSYS.tar.bz2?download
  2. untar and copy the m4.exe-file in the end of the path to C:\msys\1.0\bin

6. Update environment variables

The below is copied direct from ​http://www.mingw.org/wiki/HOWTO_Install_the_MinGW_GCC_Compiler_Suite#toc33

Environment Settings

When you install command line tools, such as MinGW, or !GnuWin32 tools, you have to tell the command line interpreter where to find them; this is usually accomplished by adding the appropriate directory names to the PATH variable in your environment. Typically, it is your responsibility to do this; please do not expect the installer, (if you used one), to do it for you.

Warning: Adding entries to the PATH is normally benign. However, if you delete, you may mess up your PATH string, and you could seriously compromise the functioning of your computer. Please be careful.

  1. Right-click on "My Computer" and select "Properties".
  2. Click Advanced -> Environment Variables.
  3. In the box entitled "System Variables" scroll down to the line that says "PATH" and double-click the entry.
  4. You will be presented with a dialog box with two text boxes, the bottom text box allows you to edit the PATH variable. It is very important that you do not delete the existing values in the PATH string, this will cause all sorts of problems for you!
  5. Scroll to the end of the string and at the end add ";<installation-directory>\bin". Here <installation-directory> is the full absolute path name of the installation directory; if you accepted the defaults when installing tar and gzip, then for these, it will (probably) be C:\Program Files\!GnuWin32, while for MinGW it will be C:\MinGW\bin, (if you kept to the recommended default installation directory). Don't forget the semicolon; this separates the entries in the PATH.
  6. press OK -> OK -> OK and you are done.

Set the environment variable HOME to C:\msys\1.0\home. Create it if it doesn't already exist.

7. Installing LibIconv

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

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

# cd /c/projects
# tar xvfz libiconv-1.13.1.tar.gz
# cd libiconv-1.13.1
# ./configure --prefix=/c/mingw
# make
# make install

Verify if the version of iconv you are running is the same as the one you just compiled (1.13): 

# iconv --version

8. Installing Autoconf, Automake and Libtool

Verify which versions of these you have with

autoconf --version etc.

If they are not newer than below then download and install. Download the source code from the GNU site:

Save the packages in the c:\projects folder.

Launch the MSYS terminal from Start->Programs->MinGW->msys or from the desktop MSYS icon. 

# cd /c/projects
# mkdir pg
# mkdir postgresql
# mkdir geos
# mkdir proj
# ls

Now you will get the folders you have copied to the directory listed. The names of the folders will be different than in this example if you have newer releases of the tools. Configure, compile and install autoconf. 

 tar xvfz autoconf-2.65.tar.gz
 cd autoconf-2.65
 ./configure --prefix=/c/mingw 
 make 
 make install
 autoconf --version

If it says you are running lower than 2.63, most likely you have another one installed in addition. Running the below will tell you which one it is picking up. 

which autoconf

Now configure, compile and install automake. 

# tar xvfz automake-1.11.tar.gz
# cd automake-1.11
# ./configure --prefix=/c/mingw
# make
# make install

Now configure, compile and install libtool. 

# tar xvfz libtool-2.2.10.tar.gz
# cd libtool-2.2.10
# ./configure --prefix=/c/mingw
# make
# make install

9. Compiling PostgreSQL

Download latest ​PostgreSQL source and untar in C:\projects\postgresql 

# cd /c/projects/postgresql
# tar xvfz postgresql-9.0.0.tar.gz
# cd postgresql-9.0.0
# ./configure --prefix=/c/projects/pg/pg90
# make
# make install
  • copy to C:\projects\pg\pg90\bin\libpq.dll from C:\projects\pg\pg90\lib

If you want to be able to do a full make check on PostGIS, Initialize the postgresql database cluster first.

10. 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 . 

# cd /c/projects/geos
# bzip2 -d -c geos-svn.tar.bz2 | tar xvf -
# ./configure --prefix=/c/projects/geos/rel-3.3.0
# 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

GEOS 3.3

If you are compiling the latest GEOS 3.2/3.3 (the SVN version), you may get an error because of a bug in MinGW. GEOS 3.2 is needed to take advantage of the new ST_Buffer enhancements in PostGIS 1.5+ and also some fixes for topology exceptions in intersects and intersection.

I had to comment out the lines as seen below, lines 159 and 166 in C:\MinGW\include\c++\3.4.5\cwchar (the same issue still exists under gcc 4.4.0) 

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

Refer to this ​MinGW bug ticket and ​mailing list entry for more details.

If you are runnning gcc 4.4.0 and you get complaints about link g++ you probably need to do this too. Change 

library_names='libstdc++.dll.a'

to 

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

in file /c/mingw/lib/libstdc++.la, as alluded to ​here.

11. Compiling Proj4

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/postgres --enable-shared --disable-static
 make
 make install

Make the libproj.dll and make it dynamically linked 

 cd /c/postgres/lib
 gcc -shared -o libproj.dll -Wl,--out-implib=libproj.dll.a -Wl,--export-all-symbols -Wl,--enable-auto-import -Wl,--whole-archive libproj.a -Wl,--no-whole-archive /c/mingw/lib/libmingw32.a

Note: The ​4.7.0 version can be used, but causes problems. More information ​here and ​here.

12. Installing C-Unit

C-Unit is a testing framework, and is needed by PostGIS 1.4 and above to run the "make check" testing step.

  1. Download ​http://sourceforge.net/projects/cunit/files/CUnit/CUnit-2.1-0-winlib.zip
  2. Extract and copy contents to C:\MinGW

13. Compiling LibXML2

  1. mkdir /c/projects/libxml
  2. cd /c/projects/libxml
  3. ​ftp://xmlsoft.org/libxml2/libxml2-2.7.6.tar.gz
  4. For windows it crashes currently unless you compile libxml statically which means

it gets embedded in the postgis-1.5.dll 

# tar xvfz libxml2-2.7.6.tar.gz 
# cd libxml2-2.7.6
# ./configure --prefix=/c/projects/libxml/libxml2-2.7.6release --disable-shared CCFLAGS=LDFLAGS="-Wl,-static" CFLAGS=-O2
# make
# make install

14. Install GTK+ Bundle

If you are compiling the shp2pgsql-gui program, you will need the GTK+ bundle.

Unzip the bundle in c:\gtkbundle and then alter the system PATH so that c:\gtkbundle\bin is in the PATH.

15. Compiling GDAL

Download latest trunk ​http://download.osgeo.org/gdal/?C=M;O=D - at this time gdal180.zip or

svn checkout from ​https://svn.osgeo.org/gdal/trunk to c:\projects\gdal\trunk

cd /c/projects/gdal/trunk/gdal (if you svn checkout need to do an sh autogen.sh before can configure) 

./configure --without-libtool --with-libtiff=internal --with-libz=/c/gtkbundle/include \
  --prefix=/c/projects/gdal/rel-trunk

--- TODO FINISH THIS ---

16. Compiling PostGIS

PostGIS 2.0

 cd /c/project/postgis
 tar xvfz postgis-2.0.0SVN.tar.gz
 cd postgis-2.0.0SVN

There is a bug not yet fixed in PostGIS 2.0 that make the shp2pgsql not produced the right output when there are schemas used refer to #748 for more details. This seems to only affect Windows. A quick hack to fix that is:

edit the loader/Makefile.in and change the line 

nls_build = @USE_NLS@

to 

#nls_build = @USE_NLS@

export PATH="/c/gtk/bin:$PATH"
export PATH="/c/projects/pg/pg90/bin/:$PATH"
export PGPORT=5439
 ./configure \
     --prefix=/c/projects/pg/pg90 \
     --with-xml2config=/c/projects/libxml/libxml2-2.7.6release/bin/xml2-config \
     --with-pgconfig=/c/pg/pg90/bin/pg_config \
     --with-geosconfig=/c/projects/geos/rel-3.3.0/bin/geos-config \
     --with-projdir=/c/projects/proj/rel-4.6.1 \
     --with-gdal=/c/projects/gdal/rel-trunk/bin/gdal-config
     --with-gui

 make clean
 make
 make install
# make check

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

Might just be me, but to get PostGIS 2.0. to work under PostgreSQL 9.0, had to do these steps right after the ./configure and then follow the rest of the steps above. The PostgreSQL 9.0 mangled the ${PERL} global having it point at a strange place. The below hack assumes you already have Perl in search path and just replaces the $(PERL) placeholder with perl executable. 

sed 's,$(PERL),perl,g' <postgis/Makefile >postgis/Makefile2
mv postgis/Makefile2 postgis/Makefile

Installing into PostgreSQL

  1. Copy the following files into your Windows PostgreSQL lib folder
    • C:\projects\pg90\lib\postgis-2.0.dll
  2. Copy the following files into your Windows PostgreSQL bin folder.
    • C:\projects\geos\rel-3.3.0\bin\libgeos-3-3-0.dll
    • C:\projects\geos\rel-3.3.0\bin\libgeos_c-1.dll
    • C:\projects\proj\rel-4.4.6\bin\libproj.dll,
    • libiconv-2.dll (from C:\MinGW\bin)
    • C:\projects\pg90\bin\shp2pgsql.exe
    • C:\projects\pg90\bin\pgsql2shp.exe
    • C:\projects\gdal\rel-trunk\lib\libgdal.dll
  3. If you compiled with-gui - you need to also copy the following files to PostgreSQL bin folder
    • shp2pgsql-gui.exe
    • And put gtk_bundle/bin in your path (if you need to distribute -- copy along the

gtk_bundle/bin and gtk_bundle/etc - hopefully this big footprint need will change for future versions)

  1. Copy the proj datum shift files to the PostgreSQL share/contrib/postgis/proj
  2. Open PGAdmin and make a new database without any template
  3. Open a new query-window to your new database
  4. Add PL/PgSQL procedural language to the new database: createlang plpgsql
  5. Run postgis.sql and spatial_ref_sys.sql from C:\projects\pg\share\contrib\

Hopefully you now have a database running your recently compiled postgis.
