Compiling using Mingw64-w64, Mingw64-w32 for 64-bit/32-bit (work in Progress)

Back to Compiling in Windows

There are issues with GEOS compile above 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. We like GCC 4.5.4 Issues are documented in ​http://trac.osgeo.org/geos/ticket/518 (also similar issue compiling Geos under windows 64-bit SDK ​http://trac.osgeo.org/geos/ticket/528 )

1. Installing Minimalist GNU for Windows-w64 (MinGW-w64)

We will use MingGW-w64 toolchain instead of the standard MingW since it has support for both 32-bit and 64-bit compiling. For this discussion we are using the binaries built for running on Windows. We haven't tried the builds designed for building windows binaries under Linux/Unix.

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-bin_x86_64-mingw_20111101_sezero.zip

mingw-w32-bin_i686-mingw_20111101_sezero.zip

  • Extract your respective zip into a folder called C:\ming64\mingw64 or c:\ming32\mingw32
  • Download the latest patch in same folder e.g. sezero_20111101-w32-update-rev.5151.zip for win32, sezero_20111101-w64-update-rev.5151.zip for win64 and extract into same respective folders.

/ NOTE to self: This may not be necessary anymore / 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 ​http://www.gaia-gis.it/spatialite-3.0.0-BETA/mingw64_how_to.html#env mingw64 is picking up the 32-bit dlls from syswow64 instead of the 64-bit dlls 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 

ws2_32.dll

To your folder: C:\ming64\x86_64-w64-mingw32\lib and then rename them adding a lib extensions so you have 

libws2_32.dll
# 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 MSYS-20110309.zip (update there is now a newer MSYS -- MSYS-20110526.zip)
  • Extract into a folder called C:\Ming64\msys (or C:\Ming32\msys)
  • launch msys.bat
  • type 
sh /postinstall/pi.sh

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. Note: You can have both if you are using windows 64-bit and we do.

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 package ( as instructed in the ​http://www.gaia-gis.it/spatialite-3.0.0-BETA/mingw64_how_to.html#env to bin of respective ming64/ming32 msys folders.

3a. Installing Autoconf, Automake and Libtool

Relaunch C:\ming64\msys\msys.bat (or c:\ming32\msys\msys.bat)

We create a file with commands like this and make sure this is included in all my compile scripts 

#if you are building for 32-bit change ming64 to ming32
export PROJECTS=/c/ming64/projects
#for a 64-bit build
export MINGHOST=x86_64-w64-mingw32
#if you are building for 32-bit change to this
#export MINGHOST=i686-w64-mingw32 

#this part is not necessary
#but we like to prefix our binary folders with
#version
export OS_BUILD=64 #change to 32 if building for 32

#if you are building for 32-bit change ming64 to ming32
mkdir ${PROJECTS}

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 ${PROJECTS}
tar -xvf autoconf-2.65.tar.gz
cd autoconf-2.65
./configure --host=${MINGHOST} --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 

cd ${PROJECTS}
tar -xvf libtool-2.4.10.tar.gz 

cd libtool-2.4.10
./configure --host=${MINGHOST} --disable-shared --prefix=/mingw
#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/pi.sh again
make clean && make && make install
libtool --version

3.b create project folders

 cd ${PROJECTS}
 mkdir pgx${OS_BUILD}
 mkdir postgresql
 mkdir geos
 mkdir proj
 mkdir docbook
 ls

GDAL

export GDAL_VER=1.9.1
cd ${PROJECTS}/gdal
wget http://download.osgeo.org/gdal/gdal-${GDAL_VER}.tar.gz
tar xvfz gdal-1.9.1.tar.gz
cd gdal-${GDAL_VER}
./configure --host=$MINGHOST}--build=x86_64-w64-mingw32 --with-threads=no --prefix=${PROJECTS}/gdal/rel-${GDAL_VER}w${OS_BUILD} 
make && make install
cd ${PROJECTS}/gdal/rel-${GDAL_VER}w${OS_BUILD}/bin
strip *.dll

DOWNLOAD DOCBOOK

cd ${PROJECTS}/docbook

Download the latest Docbook from ​http://sourceforge.net/projects/docbook/files/docbook-xsl/ 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 ​http://trac.osgeo.org/geos/ You can also use the trunk svn version ​https://svn.osgeo.org/geos/trunk which is what we use. NOTE: To take advantage of new functions like ​ST_DelaunayTriangles, you need GEOS 3.4dev which is trunk If you are using svn version, make sure to run: 

sh autogen.sh
