= Building with MingW64 w64, w32 chains = == 1. Installing Minimalist GNU for Windows-w64 (MinGW-w64) == The mingw64 for build 32-bit binaries only works for PostgreSQL 9.2+. There are changes they did in 9.2 that were never backported to 9.1 and below. So to compile PostGIS for 32-bit for 9.1 and below you need to use the regular old Msys instructions. mingw64 chain will work for 64-bit 9.0-9.3 and for 32-bit 9.2-9.3. 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 [http://sourceforge.net/apps/trac/mingw-w64/wiki/download%20filename%20structure What to download] MingW-w64 site is [http://mingw-w64.sourceforge.net] 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 ) * If you are building for 64-bit Windows download the personal build from [http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/sezero_4.5_20111101/] with name starting with '''mingw-w64-bin_x86_64-mingw_20111101_sezero.zip''' * If you are building for 32-bit Windows download one of the binary packages from [http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/sezero_4.5_20111101/] with name starting with '''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. There might be a newer patch use that one. /** 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 [http://sourceforge.net/apps/trac/mingw-w64/wiki/MSYS mingw-w64 with MSYS] and repeated here for completeness * download [http://sourceforge.net/projects/mingw-w64/files/External%20binary%20packages%20%28Win64%20hosted%29/MSYS%20%2832-bit%29/ 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 {{{ export OS_BUILD=64 if [[ "${OS_BUILD}" == "64" ]] ; then export MINGHOST=x86_64-w64-mingw32 else export MINGHOST=i686-w64-mingw32 fi }}} {{{ #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 * http://ftp.gnu.org/gnu/autoconf/autoconf-2.65.tar.gz * http://ftp.gnu.org/gnu/automake/automake-1.11.1.tar.gz * http://ftp.gnu.org/gnu/libtool/libtool-2.4.tar.gz {{{ 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 }}} For CUnit {{{ cd ${PROJECTS} wget http://iweb.dl.sourceforge.net/project/cunit/CUnit/2.1-2/CUnit-2.1-2-src.tar.bz2 tar -xvf CUnit-2.1-2-src.tar.bz2 cd CUnit-2.1-2 ./configure --build=${MINGHOST} --prefix=/mingw/${MINGHOST} make clean make && make install make check exit; }}}
