Compiling using MingGW-w64 for both 32-bit and 64-bit
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
- If you are on 64-bit Windows download one of the binary packages from http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Automated%20Builds/ with name
starting with mingw-w64-1.0-bin_i686-mingw_
- If you are on 32-bit Windows download one of the binary packages from http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Automated%20Builds/ with name starting with
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
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.
3a. Installing Autoconf, Automake and Libtool
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
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
3.b create project folders
cd /c/projects mkdir pg mkdir postgresql mkdir geos mkdir proj ls
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:
(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
#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.
THIS MAY NOT BE NECESSARY WITH THE MUTEX PATCH. STill fails anyway To compile you need to download and install pthreads as described here http://sourceforge.net/apps/trac/mingw-w64/wiki/Compile%20pthreads (pre-compiled binaries for both the 32-bit and 64-bit are located at http://sourceforge.net/projects/mingw-w64/files/External%20binary%20packages%20%28Win64%20hosted%29/pthreads/ in the .zip 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 ..
Apply mutex patch in http://trac.osgeo.org/proj/ticket/72
./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
Seems to give an error on make install (when trying to copy over the nad folder), but generates files in rel-4.7.0. Have to copy the nad folder manually. The .dll file is strangely called libproj-0.dll. of libproj.dll. Oh well.
6. Compiling and Installing C-Unit
Download from http://sourceforge.net/projects/cunit/ into c:\projects
cd /c/projects tar -xvf CUnit-2.1-2-src.tar.bz2 cd CUnit-2.1.2 ./configure --build=i686-w64-mingw32 --host=i686-w64-mingw32 --target=i686-w64-mingw32 make && make install
