the MinGW + MSYS environment

MinGW is an open source C/C++ compiler based on the popular gcc; MSYS is a command shell supporting a minimalistic Linux-like environment on Windows.
Using both them you can build standard open source software [ originally developed for Linux] under Windows as well, simply using the classic build tool-chain, as in:

./configure
make
make install

Quite obviously, Windows isn't exactly the same as Linux, so you cannot expect to get always an easy and painless build.
May well be you have to adapt something here and there in order to get a successful build under Windows.
The following notes are aimed exactly to this goal: allow you to avoid wasting your time while fighting against oddities that can quite easily solved.

We'll suppose you are using the current MinGW 5.1.4 and MSYS 1.0.10
So, if you have installed anything using the default settings [ the wisest thing to do], now you have the following path correspondence:

C:\msys\1.0\local will be mapped [ in the MSYS own perspective] as: /usr/local

Accordingly, this one will be the standard home for any software you'll then build and install.

---

Step 1) installing libiconv

libiconv is the standard GNU library supporting locale charsets.
Required by: libspatialite, spatialite-tools

Building under Windows is really difficult, so the easiest way is the one to install the precompiled binaries.

• download libiconv-win-x86-1.9.2.zip
• uncompress this zip-file
• then manually copy any file respectively on:
  • C:\msys\1.0\local\bin
  • C:\msys\1.0\local\include
  • C:\msys\1.0\local\lib

---

Step 2) building libz

libz is a popular library implementing Deflate, i.e. the compression algorithm used by gzip and Zip.
Required by: libpng, libtiff, librasterlite

Building under Windows is quite easy, but requires to pay some attenction.

• download the latest sources: zlib125.zip
• uncompress this zip-file
• then open an MSYS shell

cd zlib125
cp win32/Makefile.gcc .
make -f Makefile.gcc
export "INCLUDE_PATH=/usr/local/include"
export "LIBRARY_PATH=/usr/local/lib"
make install -f makefile.gcc
cp zlib1.dll /usr/local/bin
cp libzdll.a /usr/local/lib

This will build and install both the static library and the DLL as well.

Anyway this process will not generate the libz.la file (which is required to build libtiff in one of the following steps.
So in order to get a fully installed libz you have to accomplish a further operation:

• download libz.la
• and then copy this file: cp libz.la /usr/local/lib

---

Step 3) building libjpeg

libjpeg is a popular library supporting the JPEG image compression.
Required by: libtiff, librasterlite

Important notice: you can now choose between two alternative implementations:

• libjpeg is the standard, plain library
• libjpeg-turbo is a new library, that fully takes profit from the most recent Intel/AMD CPUs
  If you are planning to deploy your software on such platforms, then using libjpeg-turbo can ensure a 200% performance boost (and even more than this).
  I strongly recommend using libjpeg-turbo: both libraries share the same identical API/ABI (they are absolutely inter-changeable), but libjpeg-turbo runs in an impressively faster mode.

Building the one or the other under Windows is absolutely a plain and easy task.

How-to-build libjpeg-turbo

Please note: the NASM assembler is absolutely required: if you don't have it already installed on your system, you can download and install now.

• download the latest sources: libjpeg-turbo-1.0.0..tar.gz
• uncompress this zip-file
• then open an MSYS shell

cd libjpeg-turbo-1.0.0
./configure --prefix=/usr/local
make
make install-strip

This will build and install both the static library and the DLL as well.

How-to-build libjpeg

• download the latest sources: jpegsr8a.zip
• uncompress this zip-file
• then open an MSYS shell

cd jpeg-8a
./configure
make
make install-strip

This will build and install both the static library and the DLL as well.

---

Step 4) building libpng

libpng is a popular library supporting the PNG image compression.
Depends on: libz
Required by: librasterlite

Building under Windows is absolutely a plain and easy task.

• download the latest sources: lpng143.zip
• uncompress this zip-file
• then open an MSYS shell

cd lpng143
cp scripts/makefile.mingw .

now you have to manually edit the makefile.mingw file completing some variable defs as follows:

• DESTDIR=/usr/local
• ZLIBLIB=/usr/local/lib
• ZLIBINC=/usr/local/include

make -f makefile.mingw
cp png.h pngconf.h /usr/local/include
cp libpng.a libpng.dll.a /usr/local/lib
cp libpng14.dll pngtest-stat.exe pngtest.exe /usr/local/bin

Important notice: the latest libpng-1.4.3 doesn't supports ./configure
So you have to apply the above instructions in order to build this library.

---

Step 5) building libtiff

libtiff is a popular library supporting the TIFF image format.
Depends on: libz, libjpeg
Required by: librasterlite

Building under Windows is absolutely a plain and easy task.

• download the latest sources: tiff-3.9.4.zip
• uncompress this zip-file
• then open an MSYS shell

cd tiff-3.9.4
export "CFLAGS=-I/usr/local/include"
export "LDFLAGS=-L/usr/local/lib"
./configure
make
make install-strip

Important notice: you have to properly set the shell environment in order to retrieve the already installed libz; this is the duty of the two above export directives.

This will build and install both the static library and the DLL as well.

---

Step 6) building libproj

libproj is a library supporting coordinate's transformation between different Reference Systems [ PROJ.4]
Required by: libgeotiff, libspatialite, spatialite-tools

Building under Windows is an easy task.

• download the latest sources: proj-4.7.0.zip
• uncompress this zip-file
• then open an MSYS shell

cd proj-4.7.0
./configure --without-mutex
make
make install-strip

Important notice: may well be you'll get the following fatal errors:

pj_mutex.c:167: error: redefinition of 'pj_acquire_lock'

pj_mutex.c:65: error: previous definition of 'pj_acquire_lock' was here

pj_mutex.c:181: error: redefinition of 'pj_release_lock'

pj_mutex.c:75: error: previous definition of 'pj_release_lock' was here

pj_mutex.c:192: error: redefinition of 'pj_cleanup_lock'

pj_mutex.c:82: error: previous definition of 'pj_cleanup_lock' was here

pj_mutex.c:206: error: redefinition of 'pj_init_lock'

pj_mutex.c:91: error: previous definition of 'pj_init_lock' was here

in such an evenience you have to edit the -/src/pj_mutex.c source as follows:

33c33

< #ifndef _WIN32

---

> #if defined (_WIN32) && !defined(__MINGW32__)

40c40

< #ifndef _WIN32

---

> #if defined (_WIN32) && !defined(__MINGW32__)

---

Step 7) building libgeotiff

libgeotiff is a library supporting the GeoTIFF raster format
Depends on: libz, libjpeg, libtiff, libproj
Required by: librasterlite

Building under Windows is an easy task.

• download the latest sources: libgeotiff130.zip
• uncompress this zip-file
• then open an MSYS shell

cd libgeotiff-1.3.0
export "CFLAGS=-I/usr/local/include"
export "LDFLAGS=-L/usr/local/lib"
./configure --enable-incode-epsg
make
make install-strip

Important notice: it doesn't seem possible to build as a DLL using MinGW + MSYS. AFAIK, there is no way to do such a thing.
So you have to manually apply the following patch to circumvent this issue. Edit the /usr/local/lib/libgeotiff.la file as follows:

10c10

< library_names=''

---

> library_names='libgeotiff.a'

---

Step 8) building libgeos

libgeos is a library representing a C++ porting of JTS [ Java Topology Suite].
Required by: libspatialite, spatialite-tools

This library really is an huge and complex piece of software; building on Windows is an incredibly time consuming task, and may be quite complex.

• download the latest sources: geos-3.2.2.tar.bz2
• uncompress this zip-file
• then open an MSYS shell

cd geos-3.2.2
./configure
make
make install-strip

This will build and install both the static library and the DLL as well.

Important notice: using standard MinGW you'll get the following fatal errors:

C:/MinGW/bin/../gcc/mingw32/3.4.5/http://www.cnblogs.com/http://www.cnblogs.com/include/c++/3.4.5/cwchar:161:
error: '::swprintf' has not been declared
C:/MinGW/bin/../gcc/mingw32/3.4.5/http://www.cnblogs.com/http://www.cnblogs.com/include/c++/3.4.5/cwchar:168:
error: '::vswprintf' has not been declared

This is because GEOS sets the -ansi switch, and MinGW support for strict ANSI mode is somehow broken.
Fixing this issue requires some little hacking:

• go to the C:\MinGW\include\c++\3.4.5 dir
• edit the cwchar file [as shown in the following table], save end exit
• after applying this patch, GEOS will build without any further problem.

line 160	using ::putwchar;
line 161	// using ::swprintf;
line 162	using ::swscanf;
line 163	using ::ungetwc;
line 164	using ::vfwprintf;
line 165	#if _GLIBCXX_HAVE_VFWSCANF
line 166	using ::vfwscanf;
line 167	#endif
line 168	// using ::vswprintf;
line 169	#if _GLIBCXX_HAVE_VSWSCANF
line 170	using ::vswscanf;
line 171	#endif
line 172	using ::vwprintf;

---

Step 9) building expat

expat is a well known standard library supporting XML parsing.
Depends on: nothing
Required by: spatialite-tools

Building under Windows really is a piece-of-cake.

• download the latest sources: expat-2.0.1.tar.gz
• uncompress this tar.gz file
• then open an MSYS shell

cd expat-2.0.1
./configure
make
make install

This will build and install both the static library and the DLL as well.

---

Step 10) building libspatialite

libspatialite is the main core of SpatiaLite
Depends on: libiconv, libproj, libgeos
Required by: spatialite-tools, librasterlite

Building under Windows is an easy task.

• download the latest sources: libspatialite-amalgamation-2.4.0.zip
• uncompress this zip-file
• then open an MSYS shell

cd libspatialite-amalgamation-2.4.0
export "CFLAGS=-I/usr/local/include"
export "LDFLAGS=-L/usr/local/lib"
./configure --target=mingw32
make
make install-strip

---

Step 11) building spatialite-tools

spatialite-tools the SpatiaLite command-line management tools
Depends on: libiconv, libproj, libgeos, libspatialite, expat
Building under Windows is an easy task.

• download the latest sources: spatialite-tools-2.4.0.zip
• uncompress this zip-file
• then open an MSYS shell

cd spatialite-tools-2.4.0
export "CFLAGS=-I/usr/local/include"
export "LDFLAGS=-L/usr/local/lib"
./configure --target=mingw32
make
make install-strip

This will build and install both the static library and the DLL as well.

Please note: following the above method you'll get dynamically linked tools [i.e. depending on DLLs].
If you whish instead to build statically linked tools [i.e. self contained, not depending on DLLs], now type:

mkdir static_bin
make -f Makefile-static-MinGW
cp static_bin/* /usr/local/lib

---

Step 12) building libgaiagraphics

libgaiagraphics is a common utility library supporting graphics rendendering
Depends on: libjpeg, libpng, libtiff, libgeotiff, libz

Required by: spatialite-gui [ next-to-come releases of librasterlite and spatialite-gis]

Building under Windows is an easy task.

• download the latest sources: libgaiagraphics-0.1.zip
• uncompress this zip-file
• then open an MSYS shell

cd libgaiagraphics-0.1
export "CFLAGS=-I/usr/local/include"
export "LDFLAGS=-L/usr/local/lib"
./configure
make
make install-strip

This will build and install both the static library and the DLL.

---

Step 13) building wxWidgets MSW

wxWidgets is a popular widgets library, supporting GUI in a cross-platform fashion; MSW is the specific porting supporting Windows.
Required by: spatialite-gui, spatialite-gis

This library really is an huge and complex piece of software; building on Windows is an incredibly time consuming task, but is quite plain and easy.

• download the latest sources: wxMSW-2.8.11.zip
• uncompress this zip-file
• then open an MSYS shell

cd wxMSW-2.8.11
mkdir msw_build
cd msw_build
../configure --disable-shared --disable-debug \
    --disable-threads --enable-monolithic --enable-unicode \
    --without-libjpeg --without-libpng --without-zlib\
    --without-libtiff --without-expat --without-regex

Please note: the wxMSW ./configure is highly configurable: you must apply exactly the above settings.
Anyway, when ./configure stops, it's a good practice to check if the final report looks exactly like this:

Configured wxWidgets 2.8.11 for `i686-pc-mingw32'   Which GUI toolkit should wxWidgets use?                 msw   Should wxWidgets be compiled into single library?       yes   Should wxWidgets be compiled in debug mode?             no   Should wxWidgets be linked as a shared library?         no   Should wxWidgets be compiled in Unicode mode?           yes   What level of wxWidgets compatibility should be enabled?                                        wxWidgets 2.4      no                                        wxWidgets 2.6      yes   Which libraries should wxWidgets use?                                        jpeg               builtin                                        png                builtin                                        regex              builtin                                        tiff               builtin                                        zlib               builtin                                        odbc               no                                        expat              builtin                                        libmspack          no                                        sdl                no

now, when ./configure stops, you have to continue as usual:

make
make install-strip

---

Step 14) building libharu

libharu is an interesting and innovative library supporting generation of PDF documents.
Depends on: libz, libpng
Required by: spatialite-gis

Building under Windows is an easy task.

• download the latest sources: libharu-2.1.0.tar.gz
• uncompress this tar.gz file
• then open an MSYS shell

cd libharu-2.1.0
export "CFLAGS=-I/usr/local/include"
export "LDFLAGS=-L/usr/local/lib"
./configure
make
make install-strip

Important notice: it doesn't seem possible to build as a DLL using MinGW + MSYS. AFAIK, there is no way to do such a thing.
